The HIV-1 regulatory proteins Rev and Tat are expressed early in the virus life cycle and thus may be important targets for the immune control of HIV-1-infection and for effective vaccines. However, the extent to which these proteins are targeted in natural HIV-1 infection as well as precise epitopes targeted by human cytotoxic T lymphocytes (CTL) remain to be defined. In the present study, 57 ...
A mouse melanoma (B16) antigen was investigated at a cellular level by three blocking experiments using monoclonal antimelanoma antibodies, soluble melanoma antigen, and enzyme-treated B16 melanoma cells as inhibitors. The activity of antimelanoma cytotoxic T-lymphocytes (CTL) was specifically reduced by addition of the mixture of two monoclonal antimelanoma antibodies, one (M2590) recognizing ...
The SARS-CoV-2 virus can enter the cells using S1 viral spike (S) protein, not only by binding to ACE2, but also through other cellular receptors. These candidate receptors include CD46, which, like CD45, belongs pan-leukocyte and is expressed on all types of lymphocytes. In turn, infection accompanied damage almost compartments immune system, mainly T purpose study was evaluate expression leve...
The B10.D2 cytolytic T lymphocyte (CTL) receptor repertoire specific for the H-2Kb alloantigen has been studied by determining the reactivity patterns of monoclonal CTL against a panel of seven different H-2Kb mutants. The repertoire is extremely diverse and contains a minimum of approximately 50 different specificities against unique antigenic determinants on the H-2Kb molecule. Each specifici...
The only peptide of Sendai virus that is recognized by cytotoxic T lymphocytes (CTL) in B6 mice was found with (i) the use of recombinant vaccinia virus constructs containing separate genes of Sendai virus and (ii) a set of overlapping peptides completely spanning the identified nucleoprotein (NP) gene product. This immunodominant NP peptide is recognized by Sendai virus-specific CTL that are k...
We have developed a systems biology concept to explain the origin of systemic autoimmunity. From our studies of systemic lupus erythematosus (SLE) we have concluded that this disease is the inevitable consequence of over-stimulating the host's immune system by repeated exposure to antigen to levels that surpass a critical threshold, which we term the system's "self-organized criticality". We ob...
