national phase application of PCT Application No.
PCT/KR2017/003156, filed on Mar. 23, 2017, which claims the benefit

TECHNICAL FIELD
[0002] The present invention relates to an antibody which
specifically binds to the envelope glycoprotein of severe fever
with thrombocytopenia syndrome virus (SFTSV), the pathogen of
severe fever with thrombocytopenia syndrome (SFTS), and is used in
order to detect or diagnosis SFTSV and treat SFTS.
BACKGROUND
[0003] Severe Fever with Thrombocytopenia Syndrome (SFTS) is a new
kind of mite-mediated infectious disease, and is mostly occurred by
Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) mediated
by Haemaphysalis longicornis or Amblyomma testudinarium. SFTS was
firstly reported in China in 2009, and the disease and virus was
reported in Japan and Korea in 2012. The main symptoms of SFTS are
fever, abdominal pain, nausea, vomiting, thrombocytopenia or
leukopenia, etc., and in case of serious case, multiple organ
failure may occur and result in death. SFTS has consistently
occurred in China, Japan or Korea every year, and the fatality rate
caused thereby is very high, and it mostly occurs in the period
between spring and summer. A black-stripped field mouse is probable
as the wild host of SFTSV, and it was presumed that domestic
animals can play a role of host, since the serum antibody was found
at the high ratio in domestic animals such as goat, cow, dog or
chicken, etc. in the major outbreak areas of China. It has been
reported that the infection from person to person occurred by
mediating a body fluid of an infected person, but there is no
approved therapeutic agent or prevention method to effectively
treat SFTS until now.
[0004] There is a method of confirming an anti-SFTSV antibody titer
in blood to confirm SFTS infection. Then the anti-SFTSV antibody
titer is mostly measured with an antibody for N protein of SFTSV.
The antibody is an antibody for SFTSV internal protein exposed when
SFTSV becomes extinct. Thus, the conventional diagnosis by
confirming the anti-SFTSV antibody titer has limitation that the
existence of virus which is alive and actively acts cannot be
accurately figured out. As another method of diagnosing SFTS, the
method for detecting the RNA sequence of SFTSV in a subject derived
from a human body has been known as having high accuracy, but it
has a difficulty to isolate virus RNA of good quality from the
subject.
[0005] On the other hand, International patent publication No.
2015/053455 (WO2015/053455A1) discloses the method for detecting an
antibody for SFTSV, but specifically it does not disclose to which
antigen of SFTSV the antibody binds and the neutralization activity
of the antibody at all.
[0006] Thus, the development of an antibody or method which can
effectively detect, isolate or purify SFTSV by recovering
limitations of an inaccurate virus titer measurement method of
conventional enzyme immunoreaction diagnosis method detecting the
amount of killed SFTSV protein, or conventional low purity of virus
RNA isolation method in blood is need.
DISCLOSURE
Technical Problem
[0007] The problem to be solved by the present invention is to
provide an antibody which can effectively detect or diagnose SFTSV
and treat SFTS. In addition, the other problem to be solved by the
present invention is to provide an antibody which specifically
binds to SFTSV, particularly an envelope glycoprotein of SFTSV.
Technical Solution
[0008] To solve the technical problems, the present invention
provides a novel antibody which specifically binds to SFTSV,
particularly its envelope glycoprotein. In addition, the present
invention provides a method for effectively detecting, isolating or
purifying SFTSV using the antibody. In addition, the present
invention, a method for effectively preventing or treating SFTS
using the antibody.
[0009] As the result that the present inventors have made extensive
efforts to overcome the limitations of conventional diagnosis
methods of SFTSV, they found a novel antibody which specifically
binds to an envelope glycoprotein of SFTSV, particularly Gc or Gn,
and found that SFTSV can be effectively detected using it, to
complete the present invention.
[0010] SFTSV is a minus single strand RNA virus, and belongs to
Bunyaviridae family, phlebovirus species. The virus is a globular
virus of 80-100 nm diameter and uses Haemaphysalis longicornis as a
mediator. The genome of the virus consists of large (L), Medium (M)
and small (S) segments, and these encode 6 proteins of RNA
dependent RNA polymerase (RdRp), glycoprotein precursor (M),
glycoprotein N (Gn), glycoprotein C (Gc), nucleocapsid protein (NP)
and non-structural protein (NSs).
[0011] In the present invention, an "antibody" may include whole
antibodies and any antigen binding portion or single chains
thereof. A naturally occurring "antibody" is a glycoprotein
comprising at least two heavy chains (H) and two light chains (L)
interconnected by disulfide bonds. Each heavy chain consists of a
heavy chain variable region (VH) and a heavy chain constant region
(CH). The heavy chain constant region consists of three domains,
CH1, CH2 and CH3. Each light chain consists of a light chain
variable region (VL) and a light chain constant region (CL). The
light chain constant region consists of one domain, CL. The VH and
VL regions may be further subdivided into regions of
hypervariability, referred to as complementarity determining
regions (CDR), interspersed with regions that are more conserved,
referred to as framework regions (FR). Each VH and VL consists of
three CDRs and four FRs arranged from amino-terminus to
carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3,
CDR3, FR4. The variable regions of the heavy and light chains
contain a binding domain that interacts with an antigen.
[0012] The present invention provides an antibody which
specifically binds to an envelope glycoprotein of SFTSV,
particularly an envelope glycoprotein of SFTSV, Gc or Gn.
Preferably, the antibody may be comprise a specific amino acid
sequence as follows or consists of them. In addition, certain
modifications which are obvious in constant regions of heavy chains
and light chains are included in the scope of the present invention
in the range having same or similar binding specificity.
Furthermore, as each of those antibodies can bind to the envelope
glycoprotein of SFTSV, an antibody binding to other envelope
glycoproteins of SFTSV of the present invention can be produced by
mixing and matching VH, VL, full length light chain and full length
heavy chain sequences (amino acid sequences and nucleotide
sequences encoding the amino acid sequences).
[0013] In one example, the amino acid sequences of antibody clones
(Ab1-5) which binds to Gc envelope glycoprotein of the present
invention are shown in the following Tables 1-8.

[0047] In another exemplary embodiment, the antibody of the present
invention may comprise an amino acid sequence having at least 90%,
95%, 97%, 98% or 99% sequence identity with any one of amino acid
sequences disclosed in the above Tables 1-16, within the range that
the antibody specificity to the envelope glycoprotein of SFTSV is

antibody of the present invention may comprise a nucleic acid
having at least 90%, 95%, 97%, 98% or 99% sequence identity with
any one of nucleic acid sequences disclosed in the above Table
17.
[0048] In addition, the present invention provides a vector and a
host cell comprising the nucleic acid. The vector of the present
invention may comprise a nucleic acid encoding an amino acid
sequence of the antibody binding to the envelope glycoprotein of
SFTSV, Gc, or a nucleic acid encoding an amino acid of the antibody
binding to Gn. Otherwise, the vector of the present invention may
express a bispecific antibody, by comprising all the two kinds of
nucleic acids.
[0049] In one exemplary embodiment, the present invention provides
(1) a first recombinant DNA fragment encoding a heavy chain of the
antibody of the present invention, and (2) a second recombinant DNA
fragment encoding a light chain of the antibody of the present
invention. In another exemplary embodiment, the present invention
provides a host cell comprising a recombinant DNA fragment encoding
a heavy chain and a light chain of the present invention,
respectively. In some exemplary embodiments, the antibody or its
antigen binding fragment is a human monoclonal antibody or its
antigen binding fragment.
[0050] To express a polynucleotide encoding the antibody binding to
the envelope glycoprotein of SFTSV of the present invention,
various expression vectors can be used. To produce an antibody in a
mammalian host cell, both of virus-based or non-viral expression
vector may be used. For example, vectors such as pcDNA, pCI, pCMV
or pCEP4, and the like and host cells such as HEK293, CHO or
CHO-DG44, and the like may be used.
[0051] The host cell possessing and expressing the antibody of the
present invention may be a prokaryotic or eukaryotic cell. For
example, the host cell may be E. coli, preferably, E. coli ER2738.
HB2151, BL21 and the like, and they may be useful for cloning and
expressing the polynucleotide of the present invention. In
addition, as other microbial hosts, Bacillus, for example, Bacillus
subtilis or other intestinal bacteria, for example, Salmonella or
Serratia, or various Pseudomonas species may be used. To express
the antibody of the present invention, other microorganisms, for
example, yeasts can be used, and an insect cell combined with a
baculovirus vector may be also used.
[0052] In some preferable exemplary embodiments, a mammalian host
cell may be used for expressing and preparing the SFTSV envelope
glycoprotein binding polypeptide of the present invention. For
example, it may be a hybridoma cell line expressing an endogenous
immunoglobulin gene or a mammalian cell line possessing an
exogenous expression vector. Further, it may comprise for example,
CHO cell line, Cos cell line, HeLa cell, myeloma cell line, HEK
cell line, transformed B-cell and hybridoma, as any animal or human
cell. In addition, numerous appropriate host cell lines which can
secret an immunoglobulin can be used, and preferably, HEK293, CHO
or CHO-DG44 may be used.
[0053] In addition, the present invention provides a composition
for diagnosing SFTSV comprising one or more kinds of SFTSV envelope
glycoprotein binding molecules (for example, Gc or Gn binding
antibody or its antigen binding fragment). The composition for
diagnosis of the present invention may be usefully used for
detection, isolation or purification of SFTSV. Moreover, the
composition may further comprise one or more kinds of other agents
appropriate for diagnosing SFTSV. In addition, the present
invention provides a method for diagnosing SFTSV using the antibody
of the present invention. The method may be used for quantitative
or qualitative detection or diagnosis of SFTSV. Specifically, the
diagnosis method may comprise a diagnosis examination to determine
the expression of envelope glycoprotein and/or nucleic acid of
SFTSV and the function of envelope glycoprotein of SFTSV from a
biological sample (for example, blood, serum, cell or tissue) or a
subject who is suffering from or at risk of developing SFTS. In the
present invention, the detection includes quantitative and/or
qualitative analysis, and includes detection of existence and
absence and detection of virus titer, and this method has been
known in the art, and those skilled in the art may select a proper
method to conduct the present invention.
[0054] In the present invention, the detection of diagnosis or
diagnosis of SFTSV may be detected by radio immunoassay, western
blot, ELISA (Enzyme linked immunosorbent assay) or immune
fluorescence assay, etc. which detects an antigen-antibody complex.
In the present invention, an antigen may be labeled with a label
such as a radioactive material, enzyme or fluorescent material,
etc.
[0055] In one embodiment, the method of diagnosis of the present
invention may use a complex in which the antibody to the envelope
glycoprotein of SFTSV is conjugated to magnetic beads.
Specifically, the method can more effectively detect, isolate or
purify SFTSV, using the complex in which the antibody specific to
the envelope glycoprotein of SFTSV, Gc or Gn is combined to
magnetic beads. The antibody to the SFTSV envelope
glycoprotein-magnetic bead complex combines with SFTSV existed in a
subject using properties of the antibody and at that time, when the
magnetic beads are pulled by magnetic power, viruses and other
materials in the subject are separated, thereby effectively
purifying the virus. The virus purified in this way is relatively
useful for RNA isolation, as impurities are removed, and through
this, purification result data of good quality can be obtained. In
addition, an immunochemical response using another antibody can be
processed for the virus attached to magnetic beads, and through
this, SFTSV existed in the subject can be rapidly confirmed. The
schematic figure of the diagnosis method was shown in FIG. 4.
[0056] In addition, the present invention provides a kit for
diagnosing SFTSV comprising an antibody binding to an envelope
glycoprotein of SFTSV. The kit may comprise any one or more
aforementioned antibodies and a reagent for detecting an
antigen-antibody complex. As the reagent for detecting an
antigen-antibody complex, reagents used for radio immunoassay,
ELISA (Enzyme linked immunosorbent assay) or immune fluorescence
assay and the like may be used.
[0057] For example, for the detection of the immunoreaction, the
detection reagent may be labeled directly or indirectly in the form
of sandwich. In case of direct labeling method, a serum sample used
for array, etc. may be labeled by a fluorescence label such as Cy3
or Cy5. In case of sandwich method, the detection may be performed
by combining a target protein with a labeled detection antibody,
after combining a non-labeled serum sample with an array in which a
detection reagent is attached in advance. In case of sandwich
method, as the sensitivity and specificity can be increased, the
detection in the level of pg/mL is possible. Besides that, a
radioactive material, a color material, a magnetic particle or a
dense electron particle and the like may be used as a labeling
material. A confocal microscope may be used for the fluorescence
strength, and for example, may be obtained from Affymetrix, Inc. or
Agilent Technologies, Inc, etc.
[0058] The kit of the present invention may further comprise one or
more additional components needed for binding analysis, and for
example, may further comprise a binding buffer, a reagent needed
for sample preparation, a syringe for blood collection or negative
and/or positive control. The kit of the present invention which can
comprise various detection reagents may be provided for ELISA
analysis, dip stick rapid kit analysis, microarray, gene
amplification, or immunoassay, etc. according to analysis aspects,
and proper detection reagents may be sorted according to the
analysis aspects.
[0059] In addition, the present invention provides a pharmaceutical
composition comprising the antibody binding to SFTSV envelope
glycoprotein of the present invention. Preferably, the
pharmaceutical composition may be used for prevention or treatment
of SFTS. The antibody of the present invention can effectively
prevent or treat SFTS, by neutralizing SFTSV and blocking
proliferation of virus.
[0060] In the present invention, the composition may further
contain one or more kinds of other agents appropriate for treating
or preventing an SFTSV related disease. The carrier which can be
used for the pharmaceutical composition may enhance the effect of
composition, or stabilize the composition, or make preparation of
the composition easy. The pharmaceutically acceptable carrier may
comprise a physiologically acceptable solvent, a dispersive medium,
a coating agent, an anti-bacterial agent, an anti-fungal agent, an
isotonic agent or an absorption delaying agent and the like.
[0061] In the present invention, the pharmaceutical composition may
be administered by a variety of methods known in the art, and the
administration route and/or method may vary depending on the
desired result. The pharmaceutical composition may be administered
by administration methods, for example, intravenous, intramuscular,
intraperitoneal or subcutaneous, and the like. According to the
administration route, the active compound, antibody may be coated
with a material protecting the compound from the action of acids
and other natural conditions which may inactivate the compound.
[0062] In the present invention, the composition may be a sterile
fluid. To maintain a proper fluidity, for example, a coating
material such as lecithin or a surfactant may be used. In addition,
the composition may comprise an isotonic agent (for example, sugar,
polyalcohol, mannitol, sorbitol, and sodium chloride, etc.) or an
absorption delaying agent (aluminum monostearate or gelatin,
etc.).
[0063] In the present invention, the pharmaceutical composition may
be prepared according to methods known in the art and commonly
conducted, and preferably, may be prepared under GMP condition. The
pharmaceutical composition may comprise a therapeutically effective
dose or efficacious dose of the SFTSV envelope glycoprotein binding
antibody. In addition, the dosage level of active ingredients in
the pharmaceutical composition may be enough to achieve a
therapeutic effect without toxicity to a patient.
[0064] In the present invention, the treatment dosage may be
titrated to optimize safety and efficacy. When the antibody of the
present invention is administered systemically, the range of dosage
may be about 0.0001 to 100 mg, more commonly 0.01 to 15 mg per 1 kg
of the host body weight. An exemplary treatment method entails
systemic administration once per two weeks, or once per one month,
or once per three months to 6 months. In some methods of systemic
administration, the dosage is, and in some methods, the dosage may
be adjusted to achieve the serum antibody concentration of 1 to
1000 .mu.g/mL in some methods of systemic administration and 25 to
500 .mu.g/mL in some methods. Otherwise, when less frequent
administration is required, the antibody may be administered by a
time-release agent. The dosage and frequency may be differed
according to the half-life of the antibody in a patient. In
prophylactic purposes, the relatively low dosage may be
administered at relatively infrequent intervals for a long period
of time.
[0065] In addition, the present invention provides a method for
preventing or treating SFTS using the pharmaceutical composition.
The prevention or treatment method may comprise administering the
composition comprising the antibody of the present invention in an
therapeutically effective amount. The "therapeutically effective
amount" indicates an amount of the antibody of the present
invention or the composition comprising thereof which is effective
for prevention or treatment of SFTS diseases.
[0066] In addition, the present invention provides a use of an
SFTSV envelope glycoprotein binding antibody for preparation of a
composition for diagnosis of SFTSV. For the preparation of the
composition for diagnosis, the antibody or composition comprising
thereof of the present invention may comprise additional components
such as an acceptable carrier, etc.
[0067] Furthermore, the present invention provides a use of an
SFTSV envelope glycoprotein binding antibody. The antibody which
specifically binds to SFTSV of the present invention may be used
for SFTSV diagnosis, and may be used as a diagnosis use determining
expression of the envelope glycoprotein and/or nucleic acid of
SFTSV and the function of the protein from a subject who is
suffering from or at risk of developing SFTS. In addition, the
antibody of the present invention may be used as a use of
prevention or treatment of SFTS occurred by SFTSV for a who is at
risk of developing or suffering from SFTS.
Advantageous Effects
[0068] The antibody of the present invention can specifically bind
to envelope glycoprotein of SFTSV, Gc or Gn, and thus SFTSV can be
effectively detected or diagnosed and SFTS can be treated, using
the antibody of the present invention.

DETAILED DESCRIPTION
[0073] Hereinafter, examples, etc. will be described in detail to
facilitate understanding of the present invention. However, the
examples according to the present invention can be modified into
various other forms, and the scope of the present invention should
not be construed as being limited to the following examples. The
examples of the present invention are provided to describe the
present invention more completely to those skilled in the art.
Example 1: Preparation of Cells
[0074] Vero cells derived from African green monkey kidneys were
purchased from Korean Cell Line Bank, and cultured at 37.degree. C.
under 5% carbon dioxide circumstance with Roswell Park Memorial
Institute (RPMI)-1640 medium (Welgene) supplemented with 2% heat
inactivated fetal bovine serum (Gibco) and penicillin-streptomycin
(Gibco).
Example 2: Preparation of Virus Strains
[0075] The SFTS virus used in the present experiment was KF358691
which was isolated from a serum sample of 63-year-old female
patient who was hospitalized in Seoul National University hospital
and dead in 2012 [Kim K H, Yi J, Kim G, Choi S J, Jun K I, Kim N H,
et al. Severe fever with thrombocytopenia syndrome, South Korea,
2012. Emerging infectious diseases. 2013; 19(11):1892-4]. The
isolated virus was inoculated into a single layer of Vero cells and
cultured at 37.degree. C. under 5% carbon dioxide circumstance. The
virus was proliferated in Vero cells and all the experiments were
performed at the third viral passage of virus culturing. Using
Reed-Muench method, 50% tissue culture infection dose (TCID50) was
titrated in Vero cells.
Example 3: Preparation of Recombinant SFTS Virus Glycoprotein and
Single Chain Variable Fragment Antibody Fusion Protein
[0076] The amino acid sequence of SFTS virus glycoprotein used in
the present experiment was previously reported [Kim K H, Yi J, Kim
G, Choi S J, Jun K I, Kim N H, et al. Severe fever with
thrombocytopenia syndrome, South Korea, 2012. Emerging infectious
diseases. 2013; 19(11):1892-4]. To get a DNA strand encoding the
SFTS virus glycoprotein, a human codon optimized DNA sequence
corresponding to the amino acid sequence of SFTS virus glycoprotein
of SEQ ID NO 171 (GenBank Accession No: AGT98506, amino acids
20-452 for Gn glycoprotein, amino acids 563-1035 for Gc
glycoprotein) was synthesized (GenScript).
[0077] To overexpress recombinant SFTS virus glycoprotein Gc and Gn
which were fused to human immunoglobulin G1 (IgG1) Fc region
(Gc-Fc, Gn-Fc) or fused to human Ig k-chain constant region (Gc-Ck,
Gn-Ck), the SFTS glycoprotein-encoding gene was prepared according
to the method disclosed in [Park S, Lee D H, Park J G, Lee Y T,
Chung J. A sensitive enzyme immunoassay for measuring cotinine in
passive smokers. Clinica chimica acta; international journal of
clinical chemistry 2010; 411(17-18): 1238-42], [Lee Y, Kim H, Chung
J. An antibody reactive to the Gly63-Lys68 epitope of NT-proBNP
exhibits O-glycosylation-independent binding. Experimental &
molecular medicine. 2014; 46:e114].
[0078] First of all, a DNA sequence obtained by amplifying the Fc
region of human IgG1 using 2 kinds of primers
(5'-GAGCCCAAATCTTGTGACAAAACTCAC-3') and
(5'-GGATCCTCATTTACCCGGGGACAGGGAG-3') from human marrow-derived cDNA
library (Clontech Laboratories), or the synthesized constant region
of human Ig k-chain (UniProtKB/Swiss-Prot: P01834.1) was modified
to be positioned at the DNA 3' side of gene sequence to be added.
The gene sequence to be added was cloned in a modified pCEP4 vector
(Invitrogen) to enable gene addition by Sfil restriction
enzyme.
[0079] The antibody clone was produced in the form of single chain
variable fragment-human IgG1 Fc region fusion protein (scFv-Fc)
using scFv coding DNA of each clone. Then, the vector was
transfected into HEK293F cell (Invitrogen) using polyethyleneimine
(Polysciences), and the transfected cell was cultured in
FreeStyle.TM. 293 expression medium containing 100 U/L
penicillin-streptomycin. The overexpressed recombinant SFTS virus
glycoprotein fusion protein was purified through an affinity
chromatography using A/KappaSelect column and AKTA pure
chromatography system (GE Healthcare).
Example 4: Antibody Library Construction and Biopanning
[0080] Peripheral blood monocytes of patient recovered from SFTS
were collected using Ficoll-Paque solution (GE Healthcare). The
total RNAs were separated using TRIzol reagent (Invitrogen), and
cDNA was synthesized from the total RNAs using SuperScript III
first strand cDNA synthesis kit with oligo(dT) priming. Using the
cDNA, the phage-display library of human single chain variable
fragment (scFv) was constructed using pComb3XSS phagemid vector. In
addition, to select scFv clone from the library, as disclosed in
[Barbas C F, Burton D R, Scott J K, Silverman G J. Phage display: a
laboratory manual: CSHL Press; 2004.], 4 rounds of biopanning were
performed. 3 .mu.g of recombinant SFTS virus glycoprotein Gc or Gn
human IgG1 Fc region fusion protein (Gc-Fc, Gn-Fc) was used for
coating 5.times.106 of magnetic Dynabeads M-270 epoxy beads
(Invitrogen) according to the manufacturer's instruction for each
round of biopanning. And then the beads bound with proteins were
used for biopanning procedures.
Example 5: Screening of Single Chain Variable Fragment Antibody to
SFTS Virus
[0081] To select an individual antibody clone which bound to SFTS
virus glycoproteins, the phage clone was selected form the last
round of biopanning, and scFv-display phage was prepared for phage
enzyme immunoassay. Microtiter plate (Corning) was coated with 100
ng of recombinant Gc, Gn human Ig k-chain constant region fusion
proteins (Gc-Ck, Gn-Ck) per well at 4.degree. C. overnight. The
well was blocked with 3% (w/v) BSA in 100 .mu.l of PBS at
37.degree. C. for 1 hour, and cultured with 50 .mu.l of culture
supernatant containing phage at 37.degree. C. for 2 hours, and
washed with 0.05% (v/v) Tween20 in 150 .mu.l of PBS three times.
Then, 50 ml of horseradish peroxidase (HRP)-bound anti-M13 antibody
distilled in a blocking buffer (1:5000) was added to each well, and
then the plate was cultured at 37.degree. C. for 1 hour. After
washing with 150 .mu.l of 0.05% PBST, 50 .mu.l of
2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS)
substrate solution (Pierce) was added to each well, and cultured at
the room temperature for 30 minutes. And then the absorbance of
each well was measured at 405 nm using a microplate reader
(Labsystems).
Example 6: Neutralization Analysis
[0082] The SFTS virus specific scFv-Fc fusion antibody (100
.mu.l/ml) was serially diluted to be decreased 10 folds each by
0.01 .mu.l/ml. scFvs of each concentration was mixed in an
equivalent volume of 100 TCID50 SFTS virus (strain KF358691) and
cultured at 37.degree. C. for 1 hours. Then, the virus-antibody
mixture was transferred to the single layer of Vero cells in an
8-well confocal microscope chamber and cultured at 37.degree. C.
for 1 hour. After removing the virus-antibody mixture, samples were
cultured in RPMI-1640 medium containing 2% FBS and antibiotics at
37.degree. C. under 5% carbon dioxide circumstance. Vero cells in
the 8-well confocal microscope chamber were used for immune
fluorescence assay (IFA). All the experiments were performed three
times and the relative neutralization effect was measured by
comparing with MAb 4-5 [Xiling Guo et al. A human antibody
neutralizing SFTS virus, an emerging hemorrhagic fever virus, 2013.
Clin. Vaccine Immunol. 2013; 20(9):1426-32).] as a positive control
and anti-newcastle disease virus (NDV) antibody as a negative
control
Example 7: Immune Fluorescence Analysis (IFA) and Fluorescence
Intensity Measurement
[0083] The relative neutralization effect was measured using immune
fluorescence assay (IFA). Cells with or without treatment with
virus-antibody mixture having or not having Ab10, MAb 4-5 (positive
control), anti-NDV (negative control) were cultured for 2 days. The
cells were fixed with 4% paraformaldehyde in phosphate-buffer
saline (PBS) for 1 hour. After blocking and penetrating slides with
0.1% triton X-100 in 1% fetal bovine serum (BSA), they were
cultured together with anti-SFTS virus glycoprotein Gn clone Ab6
antibody (5 .mu.l/ml) at 4.degree. C. overnight. The cells were
washed and cultured with fluorescein isothiocyanate (FITC)-bound
anti-human IgG (Pierce) at the room temperature for 1 hour.
4',6-diamidino-2-phenylindole dihydrochloride (DAPI) was used for
dying a nucleus. Samples were experimented with a confocal
microscope (Leica, Buffalo Grove, Ill., USA). Fluorescence signal
strength was measured using computer assisted Leica application
suite advanced fluorescence (LAS AF). The microscope photographs
were taken in 5 regions of each slide using .times.10/0.3 lens, and
3 median values were used for analysis. DAPI signal was set with
405 nm blue diode laser and Alexa 488 was adjusted with an argon
ion laser.
Example 8: Production of scFv Antibody to SFTS Virus
[0084] Human scFv library was biopanned for the recombinant SFTS
virus glycoprotein. After 4 rounds of panning, the antibody clone
was screened by enzyme-linked immunosorbent assay analysis (ELISA).
It was shown that 10 clones (Ab1 to 5 for Gc and Ab6 to 10 for Gn)
recognized the SFTS virus through ELISA. The ELISA analysis result
was shown in FIG. 2, and the amino acid sequences of each antibody
clone were shown in FIG. 1.
Example 9: Neutralization Activity of Antibody to SFTS Virus
[0085] The neutralization activity of scFv-hFc antibody purified
for the SFTS virus was experimented in Vero cells. Among 10 clones
(Ab1 to Ab10) experimented, Ab10 exhibited the strongest
neutralization activity. The Ab10 scFv-hFc antibody (100 .mu.l/ml)
was diluted 10 folds and titrated for 100 TCID50 SFTS virus
(KF358691 strain). The immune fluorescence analysis result and
fluorescence strength measurement result of SFTSV infection were
shown in FIG. 3.
[0086] In the immune fluorescence analysis (IFA), the cell treated
with Ab10(100 .mu.l/ml) exhibited the least virus infection and its
neutralization activity was dose-dependent. In other words, the
more the amount of MAb 10 to be treated was, the smaller the number
of cells infected by SFTS virus was. Compared with MAb 4-5
(positive control), Ab10 showed significantly high neutralization
activity. The negative control antibody did not exhibit the
neutralization activity at all.
