Abstract
Schizophrenia (SCZ) is a debilitating mental disorder with various causes involving complex interactions between genetic factors and environmental agents. The immune system plays a vital role in the pathology and function of the nervous system. Interleukin 35 (IL-35) is a regulatory and anti-inflammatory cytokine that can prevent autoimmune and inflammatory diseases. This study aimed to investigate the role of autoantibodies against some central nervous system (CNS) antigens and IL-35 serum levels in patients with Schizophrenia. This case-control study involved 80 participants. The serum levels of IL-35 were measured by enzyme-linked immunosorbent assay and the autoantibodies in the CNS by indirect immunofluorescence assay (IFA). The serum levels of IL-35 were decreased in patient groups compared to healthy subjects. Autoantibodies against N-methyl-D-aspartate receptor (NMDAR) and myelin-associated glycoprotein (MAG) were positive in 15% (6/40) and 7.5% (3/40), respectively; however, no antibodies against myelin, aquaporin-4 (AQP4), myelin oligodendrocyte glycoprotein (MOG), voltage-gated potassium channel (VGKC), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPAR), γ-butyric acid receptor type B1 γ-butyric acid receptor type B1 (GABABR), antidipeptidyl peptidase-like protein-6 (DPPX), immunoglobulin-like cell adhesion molecule 5 (IgLON5), Glycine receptor (R) and acetylcholine receptor (Ach R) were detected (No statistics were computed). We found that decreased serum IL-35 levels and the existence autoantibodies against NMDAR antigen may contribute to the pathogenesis of SCZ.

Abstract
BACKGROUND Schizophrenia is a disease of the nervous system, and immune system disorders can affect its pathogenesis. Activation of microglia, proinflammatory cytokines, disruption of the blood-brain barrier due to inflammation, activation of autoreactive B cells, and consequently the production of autoantibodies against system antigens are among the immune processes involved in neurological diseases. Interleukin-32 (IL-32) is a proinflammatory cytokine that is essential in activating innate and adaptive immune responses. This study aimed to measure the serum level of IL-32 as well as the frequency of autoantibody positivity against several nervous system antigens in patients with schizophrenia. MATERIAL AND METHODS This study was conducted on 40 patients with schizophrenia and 40 healthy individuals in the control group. Serum IL-32 levels were measured by ELISA. The frequency of autoantibodies against Hu, Ri, Yo, Tr, CV2, amphiphysin, SOX1, Zic4, ITPR1, CARP, glutamic acid decarboxylase GAD, recoverin, titin, and ganglioside antigens was measured by the indirect immunofluorescence method. RESULTS Serum IL-32 levels in patients with schizophrenia were significantly higher compared to the control group. The frequency of autoantibodies against GAD and RI antigens in patients with schizophrenia was significantly higher than in the control group. Autoantibodies were positive in 8 patients for GAD antigen and 5 patients for RI antigen. Autoantibodies were also positive in 2 patients for CV2, 1 patient for Hu, and 1 patient for CARP. Negative results were reported for other antigens. CONCLUSION Our findings suggest that elevated the serum IL-32 level and autoantibodies against GAD and RI antigens may be a reflection of immune system dysregulation in patients with schizophrenia.

Abstract
BACKGROUND Pseudomonas aeruginosa is an important opportunistic pathogen, especially in patients with compromised host defense. OBJECTIVE To prepare the conjugate of detoxified lipopolysaccharide (D-LPS) and exotoxin A toxoid (T-ETA) from P. aeruginosa in gold nanoparticles (Au NPs) in a mice model. METHODS LPS and ETA were purified from P. aeruginosa PAO1. D-LPS was conjugated withT-ETA via the amidation method. Au NPs were bound to D-LPS-T-ETA conjugate via electrostatic interaction. Mice were immunized with D-LPS, D-LPS-Au NPs, T-ETA, T-ETA-Au NPs, D-LPS-T-ETA, D-LPS-T-ETA-Au NPs, D-LPS-Au NPs+T-ETA-Au NPs, Au NPs, and phosphate-buffered saline (PBS), and specific IgG titers were determined by the ELISA and the whole-cell ELISA methods. Mice in the vaccinated and control groups were exposed to a 2×LD50 of P. aeruginosa and mortality rates were recorded for one week. RESULTS The results showed that vaccination by D-LPS, D-LPS-Au NPs, T-ETA, T-ETA-Au NPs, D-LPS-T-ETA, D-LPS-T-ETA-Au NPs and D-LPS-Au NPs+T-ETA-Au NPs induced specific IgG. Mice received the D-LPS-T-ETA-Au NPs conjugate showed significant protection against bacterial challenge. CONCLUSION These data indicate that D-LPS-T-ETA-Au NPs conjugate has a significant immunogenicity potential to be applied as a new vaccine against Pseudomonas infections.

Abstract
CD44, as a superficial cellular glycoprotein, is an essential factor in cell-cell and cell-matrix interaction. The CD44 expression level has been substantially up-regulated in breast cancer, and this upregulation facilitates tumor proliferation and angiogenesis. This study aims to evaluate the combination therapy of Jet Pei/CD44-specific-siRNA/doxorubicin in breast cancer MDA-MB468 cell line. The MTT assay, wound healing test, colony formation assay, DAPI staining, and flow cytometry were performed to investigate the tumoral cell viability, migration, clonogenesis, and apoptosis progression. The quantitative real-time PCR (qRT-PCR) was performed to demonstrate the CD44 expression level. Finally, the effect of CD44 silencing on the expression of VEGF, CXCR4, MMP9, and MiR-142-3p was measured. The combination of CD44-specific-siRNA with doxorubicin decreased tumoral metastasis, proliferation, invasion, and migration, and increased apoptosis in MDA-MB468 cells. In conclusions, CD44 can serve as a therapeutic target in breast cancer. Moreover, the combination therapy of CD44-specific-siRNA with doxorubicin can be a promising treatment for patients with breast cancer.

Abstract
Currently, many corneal diseases are treated by corneal transplantation, artificial corneal implantation or, in severe cases, keratoprosthesis. Owing to the shortage of cornea donors and the risks involved with artificial corneal implants, such as infection transmission, researchers continually seek new approaches for corneal regeneration. Corneal tissue engineering is a promising approach that has attracted much attention from researchers and is focused on regenerative strategies using various biomaterials in combination with different cell types. These constructs should have the ability to mimic the native tissue microenvironment and present suitable optical, mechanical and biological properties. In this article, we review studies that have focused on the current clinical techniques for corneal replacement. We also describe tissue-engineering and cell-based approaches for corneal regeneration.

Abstract
Tumor microenvironment consists of malignant and non-malignant cells. The interaction of these dynamic and different cells is responsible for tumor progression at different levels. The non-malignant cells in TME contain cells such as tumor-associated macrophages (TAMs), cancer associated fibroblasts, pericytes, adipocytes, T cells, B cells, myeloid-derived suppressor cells (MDSCs), tumor-associated neutrophils (TANs), dendritic cells (DCs) and Vascular endothelial cells. TAMs are abundant in most human and murine cancers and their presence are associated with poor prognosis. The major event in tumor microenvironment is macrophage polarization into tumor-suppressive M1 or tumor-promoting M2 types. Although much evidence suggests that TAMS are primarily M2-like macrophages, the mechanism responsible for polarization into M1 and M2 macrophages remain unclear. TAM contributes cancer cell motility, invasion, metastases and angiogenesis. The relationship between TAM and tumor cells lead to used them as a diagnostic marker, therapeutic target and prognosis of cancer. This review presents the origin, polarization, role of TAMs in inflammation, metastasis, immune evasion and angiogenesis as well as they can be used as therapeutic target in variety of cancer cells. It is obvious that additional substantial and preclinical research is needed to support the effectiveness and applicability of this new and promising strategy for cancer treatment.

Abstract
The aim of this study was to determine the polarization of macrophages in the tumor microenvironment, as well as the effect of soluble factors secreted from these polarized macrophages on etoposide-induced cancer cell apoptosis. We investigated the effect of soluble factors secreted from the supernatant of PC3 cells treated with TLR4 and TLR8 agonists, and etoposide on macrophage polarization at the protein level through flow cytometry and enzyme-linked immunosorbent assay. We further explored the cell cycle distribution and phagocytic activity of THP-1 cells by flow cytometry. To imitate the relationship between cancer cells and tumor-associated macrophages (TAMs), we cocultured macrophages with etoposide-treated PC3 cells. After the incubation, the apoptosis in cancer cells was assessed through FACS analysis and by annexin V and PI staining. Our results demonstrate that protein expression of M1 and M2 markers confirmed the upregulation of M1 markers upon etoposide treatment, and mixed M1/M2 phenotype upon treatment with TLR agonists-treated PC3 supernatant. In coculture methods, our results demonstrate that the apoptosis of etoposide-treated cancer cells increases in the presence of M0 macrophages and THP-1 cells incubated with the supernatant of TLR4 agonists-treated PC3 cells. These results indicate clear protective effects of M0 macrophages and THP-1 cells incubated with the supernatant of PC3 cells treated with TLR4 agonists (THP-1 + SUP + TLR4a) on etoposide-induced cancer cell apoptosis.

Abstract
Antibodies are still widely used in several programs including early research, imaging, Targeting drug delivery system, Affinity chromatography, flowcytometry technic, diagnosis and treatment. Purification of antibody is a standard approach for detection of infection agent in different species. The reservoir hosts for Leishmania infantum are Dogs and they have active role in the transmission of leishmania to humans by the bite of a sand fly belonging to genus Phlebotomus and Lutzomiya. Consequently, elimination of dogs in endemic areas and vaccination of dogs contributes to reduction of the human and canine VL cases. Serological antibody tests such as IFAT (Indirect Fluorescent Antbody Test), DFAT (Direct Fluorescent Antbody Test), ELISA (Enzyme-Linked Immunosorbent Assay), PCR (Polymerase chain Reaction Assay) have been extensively used to investigate canine infection with L. infantum. In this study we produced and purified polyclonal antibody against attenuated and wild type leishmania infantum in dogs. Anti-leishmania in dog serums precipitated with ammonium sulphate. The IgG recovered from ammonium sulphate precipitation was subject to ion exchange chromatography (IEC) and the purity of IgG was confirmed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) under reduced condition. The purity of proteins were above 95% and then purified IgG was conjugated with FITC. We determined optimum titer of dog IgG by observation parasites under fluorescent microscope. The optimum dilution of prepared FITC conjugated dog IgG was 1: 400. This polyclonal antibody can be used for other applications in research, diagnosis and clinic.

Abstract
Polyclonal antibodies against kappa light chain are used to diagnose diseases producing free light chain. The kappa and lambda light chains are products of immunoglobulin synthesis and released into the circulation in minor amounts such as serum, cerebrospinal fluid, urine and synovial fluid in normal condition. The purpose of this study was the production and purification of polyclonal immunoglobulin G (IgG) against human kappa light chains. In this study, early human IgG was purified by ion-exchange chromatography, reduced with Dithiothreitol and heavy and light chains were separated with size-exclusion chromatography. Afterward, affinity chromatography with protein L Sepharose at pH 2.00 was displayed to be a dominant condition for the separation and purification of the kappa light chain of immunoglobulins from human serum. Eventually, the rabbit was immunized by human kappa light chains. The rabbit IgG was purified and labeled with horseradish peroxidase (HRP). Direct enzyme-linked immunosorbent assay was planned to determine the titer of HRP conjugated rabbit IgG against the human kappa light chain. The optimum titer of anti-kappa IgG was 1:16000. At the result, purified polyclonal anti-kappa is useful tool in biomedical and biochemical researches and diagnostic kits.

Abstract
Background Expression of virus coat protein (CP) in Escherichia coli often leads to production of partially folded aggregated proteins which are called inclusion bodies. Grapevine fanleaf virus (GFLV) is one of the most serious and widespread grapevine virus diseases around the world and in Iran. Objective The main objective of this study was to find a simple and brief method for producing polyclonal antibodies (PAbs) to be used for immunodiagnosis of GFLV. Material and Methods An antigenic determinant in GFLV CP gene was inserted into pET-28a bacterial expression vector and the construct (pET-28a CP42) was cloned into E. coli strain BL21 (DE3). The recombinant coat protein of GFLV (CP42) was expressed and characterized by SDS-PAGE and western blot analysis using commercial anti-GFLV antibody. Expression of the CP was detected in the form of inclusion bodies in insoluble cytoplasmic fraction. Then, the inclusion bodies were isolated from the bacterial cells and injected into rabbits for PAbs production. The reaction of the antiserum was checked by ELISA assay. In order to analyze efficiency of the produced PAbs, first the infected and uninfected grapevine samples were confirmed based on morphological symptoms then the indirect plate- trapped antigen Enzyme-linked Immunosorbent Assay (IPTA-ELISA) was applied using the commercial anti GFLV antibody. In the next ELISA assay, efficiency of the raised polyclonal antibody was compared with commercial one. Results The expression of recombinant CP42 induced by IPTG was confirmed by the band of 42 kDa in SDS-PAGE and western blot. The antiserum of purified inclusion body immunized rabbit was reacted with CP42 and GFLV infected Grapevine samples. The results revealed an acceptable efficacy for prepared antibodies compared to that of commercial antibody. Conclusions It was evident that the recombinant coat protein in the form of inclusion bodies can be prepared and used as the antigen for immunizing animals in order to produce PAbs.

Abstract
Purpose: Although it has been frequently confirmed that HLA-G plays an important role in the
reproduction and pregnancy, the pattern of HLA-G gene and its protein expression are rarely
addressed in studies. Therefore we conducted this study in regard to evaluate the HLA-G gene
and its protein expression in the women’s placenta with recurrent miscarriage.
Methods: Placental samples were obtained from the women who were admitted for delivery
or abortion in Al Zahra and Taleghani hospitals, Tabriz, Iran. HLA-G gene expression was
determined by real-time polymerase chain reaction (PCR) and HLA-G protein expression was
assessed by western blotting and immunofluorescence staining in the tissue samples.
Results: The results showed a significant decrease in the expression of gene and proteins of
HLA-G in the women with recurrent miscarriage compared to the control placental tissues.
Conclusion: According to the obtained results, it was concluded that the decrement of HLA-G
gene and protein expressions are associated with recurrent miscarriage. Since there are
conflicting results from other studies, it is suggested to conduct a more comprehensive similar
study with greater sample size.

Abstract
Background Targeted co-delivery of siRNA and a chemotherapeutic drug is an attractive approach to cancer drug design and treatment. This study was carried out to design an anti-Mucin1 aptamer (Apt)-conjugated chitosan nanoparticle (NP) for targeted co-delivery of insulin-like growth factor receptor 1 (IGF-1R) Silencer siRNA and docetaxel (DTX) to SKBR3 cells. Methods Characterization of nano-drugs, cellular uptake of NPs, cell viability, and gene expression studies were evaluated based on metastatic breast cancer cells. Results The results of this study showed that NPs had spherical and smooth morphology with 110-118 nm in size and had positive zeta potential (12-14 mV). siRNA and DTX were considerably loaded into NPs. The appropriate conjugation of the Apt to the NPs was affirmed by gel electrophoresis. The Apt-conjugated NPs were observed to enhance the cellular uptake of NPs into the SKBR3 cells. Although the combination treatment significantly decreased the cell viability of SKBR3 cells, the augmentative effect was observed when Apt was conjugated to NPs. Furthermore, Apt-conjugated NPs dramatically reduced the genetic expression of IGF-1R, signal transducers and activators of transcription 3 (STAT3), matrix metalloproteinases (MMP9), and vascular growth factor (VEGF). Conclusion The targeted NPs may augment the targeting of pathways involved in tumorigenesis and metastasis of breast cancer. Therefore, more animal model experiments are needed to further clarify the efficacy and safety of this functionalized nanodrug.

Abstract
Ankylosing spondylitis (AS), an autoinflammatory disease, has been associated with impaired Endoplasmic reticulum aminopeptidase (ERAP) 1 activity, which is involved in priming antigenic peptides. The purpose of this study was to evaluate if the genetic variant of ERAP1 gene could impress the inflammation status of the AS patients.
For genotyping, 140 AS cases and 140 healthy controls were enrolled. After isolation of peripheral blood mononuclear cells (PBMCs) and DNA extraction, all the subjects were genotyped for rs27044 polymorphism using SSP-PCR assay. Total RNA of PBMCs was isolated, cDNA was synthesized, and quantitative analyses of mRNA expression of cytokines were performed via Real-time PCR using the SYBR Green Gene Expression MasterMix. To measure the concentration of cytokines in serum of subjects, ELISA was used.
It was observed that the G allele of rs27044 polymorphism was significantly prevalent in AS patients. Moreover, the GG genotype and the GG+GC dominant model had significantly different distribution between study groups. There was a significant overexpression of mRNAs of IL-17A, IL-6, IL-33, TNF-α, and IFN-γ, while IL-10 was significantly downregulated in AS patients. The ELISA results were in line with that of the gene expression analysis. No significant differences in mRNA expression and concentration of cytokine were identified among AS patients with three genotypes for rs27044 SNP.
This study replicated the association of polymorphisms in ERAP1 gene with the risk of AS in a population from Iranian. However, it did not directly determine the inflammatory profile of the AS patients.

Abstract
Purpose: Targeted treatment of breast cancer through combination of chemotherapeutic agents and siRNA had been drawing much attention in recent researches. This study was carried out to evaluate mucin1 aptamer-conjugated chitosan nanoparticles containing docetaxel and cMET siRNA on SKBR3 cells. Methods: Nano-drugs were characterized by transmission electron microscope, Zetasizer and loading efficiency calculation. siRNA entrapment onto nanoparticles, stability of siRNA-loaded nanoparticles and conjugation of mucin1 aptamer to nanoparticles were evaluated via separate electrophoresis. Cellular uptake of the targeted nanoparticles was evaluated through GFP-plasmid expression in mucin1+ SKBR3 vs. mucin1- CHO cells. Protein expression, cell viability and gene expression were assessed by Western Blotting, MTT assay, and Quantitative Real Time-PCR, respectively. Results: Characterization of nano-drugs represented the ideal size (110.5± 3.9 nm), zeta potential (11.6± 0.8 mV), and loading efficiency of 90.7% and 88.3% for siRNA and docetaxel, respectively. Different gel electrophoresis affirmed the conjugation of aptamers to nanoparticles and entrapment of siRNA onto nanoparticles. Increased cellular uptake of aptamer-conjugated nanoparticles was confirmed by GFP expression. cMET gene silencing was confirmed by Western Blotting. The significant (p ≤0.0001) impact of combination targeted therapy vs. control on cell viability was shown. Results of Quantitative Real Time-PCR represented a remarkably decreased (p ≤0.0001) expression of the studied genes involving in tumorigenicity, metastasis, invasion, and angiogenesis (STAT3, IL8, MMP2, MMP9, and VEGF) by targeted combination treatment vs. control. Conclusion: The mucin1 aptamer-conjugated chitosan nanoparticles, containing docetaxel and cMET siRNA, is suggested for treatment of mucin1+ metastatic breast cancer cells. However, further studies should be conducted on animal models.

Abstract
BACKGROUND CD20-based targeting of B-cells in hematologic malignancies and autoimmune disorders is associated with outstanding clinical outcomes. Isolation and characterization of VH and VL cDNAs encoding the variable regions of the heavy and light chains of monoclonal antibodies (MAb) is necessary to produce next generation MAbs and their derivatives such as bispecific antibodies (bsAb) and single-chain variable fragments (scFv). OBJECTIVE This study was aimed at cloning and characterization of the VH and VL cDNAs from a hybridoma cell line producing an anti-CD20 MAb. METHODS VH and VL fragments were amplified, cloned and characterized. Furthermore, amino acid sequences of VH, VL and corresponding complementarity-determining regions (CDR) were determined and compared with those of four approved MAbs including Rituximab (RTX), Ibritumomab tiuxetan, Ofatumumab and GA101. RESULTS The cloned VH and VL cDNAs were found to be functional and follow a consensus pattern. Amino acid sequences corresponding to the VH and VL fragments also indicated noticeable homologies to those of RTX and Ibritumomab. Furthermore, amino acid sequences of the relating CDRs had remarkable similarities to their counterparts in RTX and Ibritumomab. CONCLUSIONS Successful recovery of VH and VL fragments encourages the development of novel CD20 targeting bsAbs, scFvs, antibody conjugates and T-cells armed with chimeric antigen receptors.

Abstract
Epidermal growth factor receptor (EGFR) as a transmembrane tyrosine kinase receptor frequently overexpresses in tumors with epithelial origin. The L2 domain from extracellular part of EGFR is involved in ligand binding and the blockage of this domain prevents activation of related signaling pathways. This study was aimed to develop a novel human scFv against EGFR L2 domain as a promising target for cancer therapy. The L2 recombinant protein was purified and used for panning a human scFv phage library (Tomlinson I). In this study, a novel screening strategy was applied to select clones with high binding and enrichment of rare specific phage clones of the L2 protein. After five biopanning rounds several specific clones were isolated which among them one phage clone with high binding was purified for further analysis. The specific interaction of selected clone against target antigen was confirmed by ELISA and western blotting. Immunofluorescence staining showed that purified scFv binds to A431 cells surface, displaying EGFR surface receptor. In the present study, we isolated for the first time a novel human scFv against EGFR L2 domain. This study can be the groundwork for developing more effective diagnostic and therapeutic agents against EGFR overexpressing cancers using this novel human anti-L2 ScFv.

Abstract
BACKGROUND CD20 is a surface antigen, which is expressed at certain stages of B-cell differentiation. Targeting the CD20-positive B-cells with therapeutic monoclonal antibodies (MAbs) has been an effectual strategy in the treatment of hematologic malignancies such as non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). Initial success with Rituximab (RTX) has encouraged the creation and development of more effective CD20 based therapeutics. However, treatment with conventional MAbs has not been adequate to overcome the problems such as refractory/ relapsed disease. In this regard, new generations of MAbs with enhanced affinity or improved anti-tumor properties have been developed. OBJECTIVE CD20 directed therapeutics have heterogeneous features and mechanisms of action. Hence, having sufficient knowledge on the immunological and molecular aspects of CD20 based cancer therapy is necessary for predicting the clinical outcomes and taking the necessary measures. METHOD An extensive search was performed in PubMed and similar databases for peer-reviewed articles concerning the biology, function and characteristics of CD20 molecule as well as the mechanisms of action and evolutionary process of CD20 targeting agents. RESULTS This review provides information about the current situation of CD20 targeting immunotherapeutics including MAbs, bispecific antibodies (which exert multiple functions or involve Tcells in tumor elimination) and CAR T-cells (engineered T-cells armed with chimeric antigen receptors). Moreover, limitations, challenges and available solutions regarding the application of CD20 targeting treatments are addressed. CONCLUSION Utilization of CD20-targeted therapeutics, due to their diverse properties, requires special considerations.

Abstract
Ankylosing spondylitis (AS) is a chronic immune-mediated inflammatory disease that affects both axial and peripheral skeletons as well as soft tissues. Recent investigations offer that disease pathogenesis is ascribed to a complex interplay of genetic, environmental, and immunological factors. Until now, there is no appropriate method for early diagnosis of AS and the successful available therapy for AS patients stay largely undefined. MicroRNAs (miRNAs), endogenous small noncoding RNAs controlling the functions of target mRNAs and cellular processes, are present in human plasma in a stable form and have appeared as possible biomarkers for activity, pathogenesis, and prognosis of the disease. In the present review, we have tried to summarize the recent findings related to miRNAs in AS development and discuss the possible utilization of these molecules as prognostic biomarkers or important therapeutic strategies for AS. Further examinations are needed to determine the unique miRNAs signatures in AS and characterize the mechanisms mediated by miRNAs in the pathology of this disease.

Abstract
In present study an optimized protocol for the separation of antibodies into antigen-binding fragments F(ab')2 using pepsin digestion was investigated. The production of these fragments is a consequential step in the development of medical research, treatment and diagnosis. For production of polyclonal antibody rabbit received antigen in four steps. The rabbit serum at 1/128000 dilution showed high absorbance in reaction with human IgG at the designed ELISA method. Rabbit IgG was purified by Ion-Exchange Chromatography (IEC) method. Purity was assessed by SDS-PAGE method. In non-reduced condition only one band was seen in about 150 kDa MW position and in reduced form, two bands were seen in 50 and 25 kDa MW positions. Rabbit IgG was digested by pepsin enzyme. The antibody fragments solution was applied to Gel filtration column to isolate the F(ab')2. Non-reduced SDS-PAGE for determining the purity of F(ab')2 fragment resulted in one band in 100 kDa corresponds to F(ab')2 fragment and a band in 150 kDa MW position corresponds to undigested IgG antibodies. The activities of FITC conjugated F(ab')2 fragment and commercial ones were compared using flowcytometry method. The activity results implied that the FITC conjugated- anti human F(ab')2 fragment worked as efficiently as the commercial one.

Abstract
Antibodies are a class of biomolecules that has an important role in the immune system and lots of applications in biotechnological methods and in pharmaceutics. Production and purification of antibodies in laboratory animals is one of the first ways to manufacture of these prominent tools. The obtained antibodies from these process could be used in various types of bioassay techniques such as enzyme linked immunosorbent assay (ELISA), radioimmunoassay, etc. Also, antibodies employed in diagnostics applications in humans and other animals in order to detect specific antigens. In this study, we aimed to produce and purify anti-dog IgG via immunizing rabbits with dog IgG in combination with Freund's adjuvant. Polyclonal IgG were purified by ion exchange chromatography and then the purified antibody was labeled with horse radish peroxidase (HPR). Direct ELISA was used to determine the optimum titer and cross-reactivity of HRP conjugated IgG. The purity of various IgG preparations and the optimum dilution of prepared HRP conjugated IgG, respectively, was about 95.00% and 1:8000. This study showed that efficiency ion-exchange chromatography could be an appropriate method for purification of IgG antibodies. This antibody could be a useful tool for future dog immune diagnosis tests. This product characterization shown here sets the foundations for future work on dog IgGs.

Abstract
Fc-fusion proteins are composed of Fc region of IgG antibody (Hinge-CH2-CH3) and a desired linked protein. Fc region of Fc-fusion proteins can bind to neonatal Fc receptor (FcRn) thereby rescuing it from degradation. The first therapeutic Fc-fusion protein was introduced for the treatment of AIDS. The molecular designing is the first stage in production of Fc-fusion proteins. The amino acid residues in the Fc region and linked protein are very important in the bioactivity and affinity of the fusion proteins. Although, therapeutic monoclonal antibodies are the top selling biologics but the application of therapeutic Fc-fusion proteins in clinic is in progress and among these medications Etanercept is the most effective in therapy. At present, eleven Fc-fusion proteins have been approved by FDA. There are novel Fc-fusion proteins which are in pre-clinical and clinical development. In this article, we review the molecular and biological characteristics of Fc-fusion proteins and then further discuss the features of novel therapeutic Fc-fusion proteins.

Abstract
Purpose: Surface plasmon resonance (SPR) sensing confers a real-time assessment of molecular interactions between biomolecules and their ligands. This approach is highly sensitive and reproducible and could be employed to confirm the successful binding of drugs to cell surface targets. The specific affinity of monoclonal antibodies (MAb) for their target antigens is being utilized for development of immuno-sensors and therapeutic agents. CD20 is a surface protein of B lymphocytes which has been widely employed for immuno-targeting of B-cell related disorders. In the present study, binding ability of an anti-CD20 MAb to surface antigens of intact target cells was investigated by SPR technique. Methods: Two distinct strategies were used for immobilization of the anti-CD20 MAb onto gold (Au) chips. MUA (11-mercaptoundecanoic acid) and Staphylococcus aureus protein A (SpA) were the two systems used for this purpose. A suspension of CD20-positive Raji cells was injected in the analyte phase and the resulting interactions were analyzed and compared to those of MOLT-4 cell line as CD20-negative control. Results: Efficient binding of anti-CD20 MAb to the surface antigens of Raji cell line was confirmed by both immobilizing methods, whereas this MAb had not a noticeable affinity to the MOLT-4 cells. Conclusion: According to the outcomes, the investigated MAb had acceptable affinity and specificity to the target antigens on the cell surface and could be utilized for immuno-detection of CD20-positive intact cells by SPR method.

Abstract
Receptor tyrosine kinase-like orphan receptor (ROR1) belongs to one of the families of receptor tyrosine kinases (RTKs). RTKs are involved in the various physiologic cellular functions including proliferation, migration, survival, signaling and differentiation. Several RTKs are deregulated in various cancers implying the targeting potential of these molecules in cancer therapy. ROR1 has recently been shown to be expressed in various types of cancer cells but not in normal adult cells. Hence a molecular inhibitor of extracellular domain of ROR1 that inhibits ROR1-cell surface interaction is of great therapeutic importance. In an attempt to develop molecular inhibitors of ROR1, we screened single chain variable fragment (scFv) phage display libraries, Tomlinson I + J, against one specific synthetic oligopeptide from extracellular domain of ROR1 and selected scFvs were characterized using various immunological techniques. Several ROR1 specific scFvs were selected following five rounds of panning procedure. The scFvs showed specific binding to ROR1 using immunological techniques. Our results demonstrate successful isolation and characterization of specific ROR1 scFvs that may have great therapeutic potential in cancer immunotherapy.

Abstract
Chronic lymphocytic leukemia (CLL) is characterized by reposition of malignant B cells in the blood, bone marrow, spleen and lymph nodes. It remains the most common leukemia in the Western world. Within the recent years, major breakthroughs have been made to prolong the survival and improve the health of patients. Despite these advances, CLL is still recognized as a disease without definitive cure. New treatment approaches, based on unique targets and novel drugs, are highly desired for CLL therapy. The Identification and subsequent targeting of molecules that are overexpressed uniquely in malignant cells not normal ones play critical roles in the success of anticancer therapeutic strategies. In this regard, ROR family proteins are known as a subgroup of protein kinases which have gained huge popularity in the scientific community for the diagnosis and treatment of different cancer types. ROR1 as an antigen exclusively expressed on the surface of tumor cells can be a target for immunotherapy. ROR-1 targeting using different approaches such as siRNA, tyrosine kinase inhibitors, cell therapy and antibody induces tumor growth suppression in cancer cells. In the current review, we aim to present an overview of the efforts and scientific achievements in targeting ROR family, particularly ROR-1, for the diagnosis and treatment of chronic lymphocytic leukemia (CLL).

Abstract
There are many studies related to the production of a ELISA kit for diagnosing virus infections. However, production of most kits depends on purification of whole virus particles, which involves the use of costly equipment and reagents. The purpose of this study was to check out if the anti-CP42 antibodies could be used as a diagnostic assay for detection of Grapevine fanleaf Virus (GFLV). In this study, recombinant GFLV coat protein gene related to selected antigenic determinants was inserted into pET-28a bacterial expression vector and the construct (pET-28a CP42) was cloned into E. coli strain (DE3). Expressed protein was verified with western blotting assay by the use of commercially available anti-GFLV antibody. The recombinant protein was purified using nickel-nitrilotriacetic acid (Ni-NTA) resin. Balb/c mice were immunized with purified protein and splenocytes of hyperimmunized mice were fused with murine myeloma Sp2/0 cells. Positive hybridomas were selected by ELISA using CP42 as coating antigen. The results showed that monoclonal antibody (MAb) specific to CP42 has been successfully generated. Efficiency of produced antibody was analyzed by ELISA and western blotting assay using some confirmed grapevine samples. The infection was confirmed previously based on morphological features and ELISA assay, performed using commercial anti-GFLV antibody. The monoclonal antibody reacted with antigen in ELISA and immunoblot method. Our results demonstrated that anti recombinant CP42 monoclonal antibodies are able to diagnose whole virus in infected grapevine sample using ELISA test.

Abstract
Receptor tyrosine kinase-like orphan receptor (ROR) proteins are a conserved family of tyrosine kinase receptors that function in developmental processes including cell survival, differentiation, cell migration, cell communication, cell polarity, proliferation, metabolism, and angiogenesis. ROR1 has recently been shown to be expressed in various types of cancer cells but not normal cells. Pharmacokinetics and pharmacodynamics of single-chain Fragment variable (scFv) antibodies provide potential therapeutic advantages over whole antibody molecules. In the present study, scFvs against a specific peptide from the extracellular domain of ROR1 were selected using phage display technology. The selected scFvs were further characterized using polyclonal and monoclonal phage enzyme-linked immunosorbent assay (ELISA), soluble monoclonal ELISA, colony PCR, and sequencing. Antiproliferative and apoptotic effects of selected scFv antibodies were also evaluated in lymphoma and myeloma cancer cell lines using MTT and annexin V/PI assays. The results of ELISA indicated specific reactions of the isolated scFvs against the ROR1 peptide. Colony PCR confirmed the presence of full-length VH and Vκ inserts. The percentages of cell growth after 24 h of treatment of cells with individual scFv revealed that the scFv significantly inhibited the growth of the RPMI8226 and chronic lymphocytic leukemia (CLL) cells in comparison with the untreated cells ( p < 0.05). Interestingly, 24-h treatment with specific scFv induced apoptosis cell death in the RPMI8226 and CLL cells. Taken together, our results demonstrate that targeting of ROR1 using peptide-specific scFv can be an effective immunotherapy strategy in hematological malignancies.

Abstract
Purpose: EGFRvIII as the most common mutant variant of the epidermal growth factor receptor is resulting from deletion of exons 2-7 in the coding sequence and junction of exons 1 and 8 through a novel glycine residue. EGFRvIII is highly expressed in glioblastoma, carcinoma of the breast, ovary, and lung but not in normal cells. The aim of the present study was identification of a novel single chain antibody against EGFRvIII as a promising target for cancer therapy. Methods: In this study, a synthetic peptide corresponding to EGFRvIII protein was used for screening a naive human scFv phage library. A novel five-round selection strategy was used for enrichment of rare specific clones. Results: After five rounds of screening, six positive scFv clones against EGFRvIII were selected using monoclonal phage ELISA, among them, only three clones had expected size in PCR reaction. The specific interaction of two of the scFv clones with EGFRvIII was confirmed by indirect ELISA. One phage clone with higher affinity in scFv ELISA was purified for further analysis. The purity of the produced scFv antibody was confirmed using SDS-PAGE and Western blotting analyses. Conclusion: In the present study, a human anti- EGFRvIII scFv with high affinity was first identified from a scFv phage library. This study can be the groundwork for developing more effective diagnostic and therapeutic agents against EGFRvIII expressing cancers.

Abstract
Antibodies are essential tools of biomedical and biochemical researches. Polyclonal antibodies are produced against different epitopes of antigens. Purified F(ab')2 can be used for animal's immunization to produce polyclonal antibodies. Human immunoglobulin G (IgG) was purified by ion exchange chromatography method. In all stages verification method of the purified antibodies was sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Purified IgG was digested by pepsin enzyme and F(ab')2 fragment was purified by gel filtration separation method. For production of polyclonal antibody, rabbit was immunized by purified F(ab')2 and antibody production was investigated by enzyme-linked immunosorbent assay. Purified anti-IgG F(ab')2 was conjugated with fluorescein isothiocyanate. Ion exchange chromatography purification yielded 38 mg of human IgG antibody. The results of SDS-PAGE in reduced and non-reduced conditions showed bands with 25-30 kDa molecular weight (MW) and 50-kDa respectively and a distinct band with 150 kDa MW. The results of non-reduced SDS-PAGE for determining the purity of F(ab')2 fragment showed one band in 90 kDa and a band in 150 kDa MW position. Purification by Ion exchange chromatography method resulted about 12 mg rabbit polyclonal antibody. Flow cytometry showed generated polyclonal antibody had an acceptable activity compared to commercial antibody. Taking together, purified IgG F(ab')2 and polyclonal anti-IgG F(ab')2 are useful tools in biomedical and biochemical researches and diagnostic kits.

Abstract
EGFRvIII, a mutant form of epidermal growth factor receptor is highly expressed in glioblastoma, carcinoma of the breast, ovary, and lung but not in normal cells. This tumor specific antigen has emerged as a promising candidate for antibody based therapy of several cancers. The aim of the present study was isolation and characterization of a human single chain antibody against EGFRvIII as a promising target for cancer therapy. For this, a synthetic peptide corresponding to EGFRvIII protein was used for screening the naive human scFv phage library. Selection was performed using a novel screening strategy for enrichment of rare specific clones. After five rounds of screening, six positive scFv clones against EGFRvIII were selected using monoclonal phage ELISA, among them, a clone with an amber mutation in VH CDR2 coding sequence showed higher reactivity. The mutation was corrected through site directed mutagenesis and then scFv fragment was expressed after subcloning into the bacterial expression vector. Expression in BL21 pLysS resulted in a highly soluble scFv appeared in soluble fraction of E. coli lysate. Bioinformatic in silico analysis between scFv and EGFRvIII sequences confirmed specific binding of desired scFv to EGFRvIII in CDR regions. The specific reactivity of the purified scFv with native EGFRvIII was confirmed by cell based ELISA and western blot. In conclusion, human anti- EGFRvIII scFv isolated from a scFv phage library displayed high reactivity with EGFRvIII. The scFv isolated in this study can be the groundwork for developing more effective diagnostic and therapeutic agents against EGFRvIII expressing cancers.

Abstract
Glomalin is a specific fungal glycoprotein produced by arbuscular mycorrhizal (AM) fungi belonging to the Glomerales which could efficiently sequestrate heavy metals. The glomalin has been introduced as a heat shock protein and there are evidences that increasing levels of heavy metals could enhance its production. We examined the influence of Cd concentrations on glomalin production by AM fungus, as well as its contribution to the sequestration of Cd in both pot and in vitro culture conditions. Pot experiment was carried out using pure sand with Trifolium repens L. as host plant, mycorrhized by Rhizophagus irregularis and treated with Cd levels of 0, 15, 30, and 45 μM. In vitro experiment was performed in two-compartment plates containing the transformed carrot roots mycorrhized with the same fungus and treated with Cd levels of 0, 0.001, 0.01, and 0.1 mM. The immunoreactive and Bradford reactive glomalin contents in both experiments increased as so raising Cd concentration. Total Cd sequestrated by hyphal glomalin in both cultures was significantly increased as the levels of Cd increased. The highest contents of Cd sequestration in pot (75.78 μg Cd/mg glomalin) and in vitro (11.44 μg Cd/mg glomalin) cultures were recorded at the uppermost levels of Cd, which significantly differed with other levels. Our results suggested that under Cd-induced stress, stimulated production of glomalin by AM fungus may be a protective mechanism against the toxic effect of Cd.

Abstract
Bacteriophages are specific antagonists to bacterial hosts. These viral entities have attracted growing interest as optimal vaccine delivery vehicles. Phages are well-matched for vaccine design due to being highly stable under harsh environmental conditions, simple and inexpensive large scale production, and potent adjuvant capacities. Phage vaccines have efficient immunostimulatory effects and present a high safety profile because these viruses have made a constant relationship with the mammalian body during a long-standing evolutionary period. The birth of phage display technology has been a turning point in the development of phage-based vaccines. Phage display vaccines are made by expressing multiple copies of an antigen on the surface of immunogenic phage particles, thereby eliciting a powerful and effective immune response. Also, the ability to produce combinatorial peptide libraries with a highly diverse pool of randomized ligands has transformed phage display into a straightforward, versatile and high throughput screening methodology for the identification of potential vaccine candidates against different diseases in particular microbial infections. These libraries can be conveniently screened through an affinity selection-based strategy called biopanning against a wide variety of targets for the selection of mimotopes with high antigenicity and immunogenicity. Also, they can be panned against the antiserum of convalescent individuals to recognize novel peptidomimetics of pathogen-related epitopes. Phage display has represented enormous promise for finding new strategies of vaccine discovery and production and current breakthroughs promise a brilliant future for the development of different phage-based vaccine platforms.

Abstract
BACKGROUND Human leukocyte antigen-G (HLA-G) is a non-classical class I molecule highly expressed by extravillous cytotrophoblast cells. Due to a single base pair deletion, its function can be compensated by other isoforms. Investigating the frequency of null allele in Recurrent Miscarriage (RM) subjects could be useful in understanding the relationship between frequency of this allele and RM in a given population. OBJECTIVE This study aimed to determine the frequency of HLA-G*0105N null allele and its potential association with down-regulation of HLA-G in subjects with RM. MATERIALS AND METHODS Western blotting was used to assess the level of HLA-G protein expression. For investigating the frequency of HLA-G*0105N null allele in RM subjects, PCR-RFLP method was used. Exon 3 of HLA-G gene was amplified by polymerase chain reaction (PCR). Subsequently, PpuM-1 enzyme was employed to digest the PCR products and fragments were analyzed using gel electrophoresis. RESULTS Digestion using restriction enzyme showed the presence of heterozygous HLA-G*0105N null allele in 10% of the test population. Western blotting results confirmed the decrease in expression of HLA-G in the placental tissue of subjects with RM compared to subjects who could give normal birth. CONCLUSION The frequency of heterozygous HLA-G*0105N null allele was high to some extent in subjects with RM. The mutation rate in subjects suggested that there is a significant association between RM and frequency of mutations in this allele.

Abstract
To concentrate a potent anticancer drug (Arteether) in tumor microenvironment, we encapsulated it in biodegradable and pH sensitive polyurethane (PU) nanomicelles (NMs). The nanocomplex was characterized by Fourier transform infrared (FTIR), dynamic light scattering (DLS). The loading capacity and release profile in pH of 5.4 and 7.4 were considered. The cytotoxicity effect was evaluated in vitro and in vivo settings. The level of IFN-γ and IL-4 cytokines of mice splenocytes were assessed by enzyme-linked immunosorbent assay (ELISA). The nanocomplex showed negative zeta charge of -26.2 mV, size of 42.30 nm and high loading capacity (92%). Release profile showed a faster rate of drug liberation at pH 5.4 as compared to that of pH 7.4. It indicated significant inhibitory effect on the growth of 4T1 cell line and increased IFN-γ level.

Abstract
Inflammation is inseparable part of different diseases especially cancer and autoimmunity. During inflammation process toll like receptor 4(TLR4) responds to lipopolysaccharide (LPS), one of the bacterial components, and TLR4 signaling leads to interleukine-1 receptor associated kinase-1 (IRAK1) and tumor necrosis factor (TNF) receptor associated factor6 (TRAF6) activation which ultimately results in nuclear factor- ĸB (NF-ĸB) activation as the main transcription factor of inflammatory cytokines. Conversely, NF-ĸB over activation induces miR-146a in innate immune cells which can consequently reduce TRAF6, IRAK1, and NF-ĸB activation in a negative feedback. G2013 is a novel designed non-steroidal anti-inflammatory drug (NSAID) which was recently shown to be effective in experimental autoimmune encephalomyelitis (EAE) mouse model. The aim of this study was to evaluate G2013 effects on inflammatory (IRAK1 and TRAF6) and anti-inflammatory (miR-146a) factors of TLR4 signaling pathway. For this purpose, cytotoxicity of G2013 has been evaluated by MTT assay. Expression level of miR-146a in PBMCs and IRAK1 along with TRAF6 in HEK-293 TLR4 cells have been determined using real time PCR. Our results showed that IC50 of G2013 was 25μg/ml, thus 5 and 25 μg/ml concentrations used for further treatments as low dose and high dose concentrations. Our results showed that IRAK1 expression reduced between 5 to 8 fold after treatment by G2013 in a dose dependent manner (p<0.001). In parallel TRAF6 expression declined between 3 to 10 fold dose dependently (p<0.05). However, miR-146a expression was not affected after treatment with low dose and high dose of G2013. In conclusion our data showed that G2013 can regulate TLR4 signaling pathway during inflammation by reducing downstream signaling molecules, IRAK1 and TRAF6 without altering miR-146a expression.

Abstract
BACKGROUND There are conflicting findings about relationship between depression and anger with immunological parameters. OBJECTIVE To investigate the relationship between anger patterns and immune system in depressed patients. METHODS Thirty-five patients with major depressive disorder were selected according to DSM-IV criteria. The Hamilton Depression Scale and Spielberger Anger questionnaires were used to determine severity of depression and "anger expression pattern", respectively. The control group without a previous history of mental illness was also selected. In the group of patients with moderate depression, serum IgA levels and NK cell percentage were measured. RESULTS Mean differences of all types of "anger expression pattern", including; "state-trait anger", "anger expression out", "anger expression in", "anger control out" and "anger control in", between study and control groups, were statistically significant (p<0.05). Difference in mean serum levels of IgA in either group was not significant (p=0.9), but the mean difference was significant in terms of NK-cell percentage in both groups (p=0.04). There was no significant relationship between IgA levels and percentage of NK- cell with all types of "anger expression pattern" in both groups. Only in the control group, IgA had significant correlation with anger control out (p=0.04). CONCLUSION Moderately depressed patients versus control group had higher Spielberger scores in all types of anger expression pattern except anger control-out and anger control-in. We found no evidence supporting the relationship between" anger expression pattern" and IgA levels and NK cell percentage; however, it seems that depression itself causes reduced number of NK cells and increased IgA levels.

Abstract
Human Toll-like receptors (TLRs) are a family of transmembrane receptors, which play a key role in both innate and adaptive immune responses. Beside of recognizing specific molecular patterns that associated with different types of pathogens, TLRs may also detect a number of self-proteins and endogenous nucleic acids. Activating TLRs lead to the heightened expression of various inflammatory genes, which have a protective role against infection. Data rising predominantly from human patients and animal models of autoimmune disease indicate that, inappropriate triggering of TLR pathways by exogenous or endogenous ligands may cause the initiation and/or perpetuation of autoimmune reactions and tissue damage. Given their important role in infectious and non-infectious disease process, TLRs and its signaling pathways emerge as appealing targets for therapeutics. In this review, we demonstrate how TLRs pathways could be involved in autoimmune disorders and their therapeutic application.

Abstract
BACKGROUND Recent researches have demonstrated that human T-cell immunoglobulin mucin 1 (TIM-1) glycoprotein plays important roles in regulation of autoimmune and allergic diseases, as well as in tumor immunity and response to viral infections. Therefore, targeting TIM-1 could be a potential therapeutic approach against such diseases. OBJECTIVES In this study, we aimed to express TIM-1 protein on Human Embryonic kidney (HEK) 293T cell line in order to have an available source of the TIM-1 antigen. MATERIALS AND METHODS The cDNA was synthesized after RNA extraction from peripheral blood mononuclear cells (PBMC) and TIM-1 cDNA was amplified by PCR with specific primers. The PCR product was cloned in pcDNA™3.1/Hygro (+) and transformed in Escherichia coli TOP 10 F'. After cloning, authenticity of DNA sequence was checked and expressed in HEK 293T cells. Finally, expression of TIM-1 was analyzed by flow cytometry and real-time PCR. RESULTS The result of DNA sequencing demonstrated correctness of TIM-1 DNA sequence. The flow cytometry results indicated that TIM-1 was expressed in about 90% of transfected HEK 293T cells. The real-time PCR analysis showed TIM-1 mRNA expression increased 195-fold in transfected cells compared with un-transfected cells. CONCLUSIONS Findings of present study demonstrated the successful cloning and expression of TIM-1 on HEK 293T cells. These cells could be used as an immunogenic source for production of specific monoclonal antibodies, nanobodies and aptamers against human TIM-1.

Abstract
Pseudomonas aeruginosa is an opportunistic bacterium that causes serious nosocomial infection in immunocompromised patients. The aim of this study was to prepare a fusion protein consisting of exotoxin A (ExoA) and flagellin (Fla) from P. aeruginosa and to evaluate its potential as a vaccine candidate against P. aeruginosa infection. The genes encoding for ExoA and Fla proteins were cloned in-frame and expressed in Escherichia coli. The recombinant ExoA-Fla fusion protein was purified by Ni-NTA affinity chromatography. Mice were immunized subcutaneously with ExoA, Fla, and ExoA-Fla fusion proteins, and the humoral immune response was evaluated by ELISA method. The immunized and control group mice were challenged with a 2× LD50 (7.5 × 10(7) CFU) of P. aeruginosa for the protection assay. The results indicated that vaccination with Fla, ExoA, and ExoA-Fla fusion proteins produced a significant amount of specific immunoglobulin G antibodies. Immunization of mice with ExoA-Fla fusion protein showed significant protection against intraperitoneal challenge with 7.5 × 10(7) CFU (2× LD50) P. aeruginosa. Results of this study suggest that recombinant ExoA-Fla fusion protein is a highly immunogenic protective protein showing promise as a vaccine candidate against P. aeruginosa.

Abstract
Tetanus is caused by the tetanus neurotoxin (TeNT), a 150 kDa single polypeptide molecule which is cleaved into active two-chain molecules composed of a 50 kDa N-terminal light (L) and a 100 kDa C-terminal heavy (H) chains. Fragment C is further subdivided into two subdomains: the proximal HCN subdomain and the extreme carboxy subdomain, HCC. HCC is considered as an immunodominant part of TeNT and is responsible for TeNT binding activity to neurons.In the present study, we investigated the ability of recombinant HCC(r HCC) to induce T cell activation. Our results showed that recombinant HCC has a stimulatory effect on IFN-γ secretion by T cells after 48h co-incubation in the presence of anti-TLR-2 Ab. Also, Hcc can induce the expression of CD69 on T cells.Our finding indicated that stimulatory effects of HCC on T cells are TLR-2 independent and anti-TLR-2 inhibitory antibody fails to neutralize HCC stimulatory effects on T cells.Furthermore, HCC is critical for immunogenic activity of TeNT and is able to induce T cells through TLR-2 independent pathway.
