Cognate antigen engagement on parenchymal cells stimulates CD8+ T cell proliferation in situ
T-cell responses are initiated upon cognate presentation by professional antigen presenting cells in lymphoid tissue. T cells then migrate to inflamed tissues, but further T-cell stimulation in these parenchymal target sites is not well understood. Here we show that T-cell expansion within inflamed tissues is a distinct phase that is neither a classical primary nor classical secondary response....
متن کاملCognate Antigen Stimulation Generates Potent CD8+ Inflammatory Effector T Cells
Inflammatory reactions are believed to be triggered by innate signals and have a major protective role by recruiting innate immunity cells, favoring lymphocyte activation and differentiation, and thus contributing to the sequestration and elimination of the injurious stimuli. Although certain lymphocyte types such as TH17 cells co-participate in inflammatory reactions, their generation from the...
متن کاملAutoregulatory CD8 T cells depend on cognate antigen recognition and CD4/CD8 myelin determinants
OBJECTIVE To determine the antigenic determinants and specific molecular requirements for the generation of autoregulatory neuroantigen-specific CD8(+) T cells in models of multiple sclerosis (MS). METHODS We have previously shown that MOG35-55-specific CD8(+) T cells suppress experimental autoimmune encephalomyelitis (EAE) in the C57BL/6 model. In this study, we utilized multiple models of E...
متن کاملMemory CD8+ T cell responses expand when antigen presentation overcomes T cell self-regulation.
Antimicrobial memory CD8+ T cell responses are not readily expanded by either repeated infections or immunizations. This is a major obstacle to the development of T cell vaccines. Prime-boost immunization with heterologous microbes sharing the same CD8+ epitope can induce a large expansion of the CD8+ response; however, different vectors vary greatly in their ability to boost for reasons that a...
متن کاملAdoptive immunotherapy against experimental visceral leishmaniasis with CD8+ T cells requires the presence of cognate antigen.
CD8+ T cells have a protective role in experimental visceral leishmaniasis. However, the observation that inflammatory cytokines induce bystander activation of CD8+ T cells questions the need for antigen-dependent effector function. Here, we demonstrate that successful adoptive immunotherapy with CD8+ T cells is strictly dependent upon the presence of cognate antigen.
