The fine specificity of alloimmune cytotoxic T lymphocytes (CTL) was investigated in CTL responses across the smallest known H-2 differences, those based on mutation at a single H-2 locus. CTL were generated in all possible mixed lymphocyte culture (MLC) combinations among seven H-2Kb mutants and the mouse strain of origin, C57BL/6 (B6-H-2b). CTL were also generated in all F1 hybrid responder/h...
HTLV-I is a transforming human retrovirus that is an etiologic agent of adult T cell leukemia/lymphoma. To investigate the effects of this virus on T cell functions, two OKT3+, OKT4+, OKT8- cytotoxic clones (8.7 and 8.8) specific for allogeneic cells bearing DPw2, a class II histocompatibility antigen, were studied before and after infection with HTLV-I. The clones retained cytotoxic function f...
CD8⁺cytotoxic T cells, CD4⁺ helper and regulatory cells interact differently with cancer. CD8⁺ cytotoxic recognize the antigens presented by cancer kill in various ways. recruit other immune promote them to destroy cells. On hand, suppress cell proliferation response of both This suppressive mechanism often leads progression These cell-cancer interactions can render conventional treatments inef...
Naive T cells differentiate into various effector T cells, including CD4(+) helper T cell subsets and CD8(+) cytotoxic T cells (CTL). Although cytotoxic CD4(+) T cells (CD4 +: CTL) also develop from naive T cells, the mechanism of development is elusive. We found that a small fraction of CD4(+) T cells that express class I-restricted T cell-associated molecule (CRTAM) upon activation possesses ...
