SV40 large tumor Ag (Tag) contains four H-2b-restricted (I, II/III, IV, and V) CTL epitopes. A hierarchy exists among these CTL epitopes. CTL directed against epitopes I, II/III, and IV are readily detected following immunization of H-2b mice with SV40, Tag-transformed syngeneic cells, or a vaccinia recombinant that expresses full-length Tag, while epitope V-specific CTL are not. The mechanisms...
The strong product G1 £G2 of graphs G1 and G2 is the graph with V (G1) × V (G2) as the vertex set, and two distinct vertices (x1, x2) and (y1, y2) are adjacent whenever for each i ∈ {1, 2} either xi = yi or xiyi ∈ E(Gi). In this note we show that for two connected graphs G1 and G2 the edge-connectivity λ(G1£G2) equals min{δ(G1£ G2), λ(G1)(|V (G2)|+2|E(G2)|), λ(G2)(|V (G1)|+2|E(G1)|)}. In additi...
Persistent Epstein-Barr virus (EBV) infection is primarily controlled by HLA class I-restricted memory cytotoxic T-cell (CTL) responses which can be reactivated in vitro by stimulation of peripheral blood lymphocytes with autologous lymphoblastoid cell lines. During an investigation of a donor infected by both type A and type B EBV, CTL specific for type B EBV were isolated. The CTL were found ...
Abstract Development of effective counteragents against the novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome 2 (SARS-CoV-2) strains, requires clear insights and information for understanding immune responses associated with it. This global pandemic has pushed healthcare system restricted movement people succumbing available therapeutics utterly warrants developme...
DIVA (differentiating infected from vaccinated animals) vaccines have proven extremely useful for control and eradication of infectious diseases in livestock. We describe here the characterization of a serologic marker epitope, so-called epitope-M201, which can be a potential target for development of a live-attenuated DIVA vaccine against porcine reproductive and respiratory syndrome virus (PR...
The pathogenesis of persistent viral infections depends critically on long-term viral loads. Yet what determines these loads is largely unknown. Here, we show that a single CD8+ T cell epitope sets the long-term latent load of a lymphotropic gamma-herpesvirus, Murid herpesvirus-4 (MuHV-4). The MuHV-4 M2 latency gene contains an H2-Kd -restricted T cell epitope, and wild-type but not M2(-) MuHV-...
Broadly cross-reactive monoclonal antibodies define epitopes for vaccine development against HIV and other highly mutable viruses. Crystal structures are available for several such antibody-epitope complexes, but methods are needed to translate that structural information into immunogens that re-elicit similar antibodies. We describe a general computational method to design epitope-scaffolds in...
This study aimed to determine the effects of dietary prebiotic Immunogen on the compensatory growth of koi carp (Cyprinus carpio) fingerlings (n= 300; 3.60 ± 0.12 g), following one-week starvation. The experiment was conducted within 60 days with three treatments. In treatment C, fish were fed with non-prebiotic diet and with no starvation period, while in treatment G1, fingerlings starved for ...
Hantaan virus, the prototypic member of the Hantavirus genus, causes hemorrhagic fever with renal syndrome in humans. We examined the human memory T-lymphocyte responses of three donors who had previous laboratory-acquired infections with Hantaan virus. We demonstrated virus-specific responses in bulk cultures of peripheral blood mononuclear cells (PBMC) from all donors. Bulk T-cell responses w...
چکیده آفلاتوکسین ها مهمترین سموم قارچی هستند که توسط گونه های مختلف آسپرژیلوس و برخی از گونه های پنی سیلیوم تولید می شوند. در این میان آفلاتوکسین های g1, b2, b1و g2 به عنوان سموم قارچی اصلی مطرح می باشند. هدف از انجام این تحقیق، استفاده بهینه از باسیلوس لیکنی فورمیس در جهت غیرفعال کردن تیپ های g1, b2, b1و g2آفلاتوکسین در محیط کشت آزمایشگاهی و آرد ماهی کیلکا بوده است. آفلاتوکسین های مورد استف...
