γδ T Cell-Mediated Immune Responses in Disease and Therapy
The role of γδ T cells in immunotherapy has gained specific importance in the recent years because of their prominent function involving directly or indirectly in the rehabilitation of the diseases. γδ T cells represent a minor population of T cells that express a distinct T cell receptor (TCR) composed of γδ chains instead of αβ chains. Unlike αβ T cells, γδ T cells display a restricted TCR re...
متن کاملTiming of CD8 T cell effector responses in viral infections
CD8 T cell or cytotoxic T lymphocyte (CTL) responses are an important branch of the immune system in the fight against viral infections. The dynamics of anti-viral CTL responses have been characterized in some detail, both experimentally and with mathematical models. An interesting experimental observation concerns the timing of CTL responses. A recent study reported that in pneumonia virus of ...
متن کاملSalmonella Modulates B Cell Biology to Evade CD8+ T Cell-Mediated Immune Responses
Although B cells and antibodies are the central effectors of humoral immunity, B cells can also produce and secrete cytokines and present antigen to helper T cells. The uptake of antigen is mainly mediated by endocytosis; thus, antigens are often presented by MHC-II molecules. However, it is unclear if B cells can present these same antigens via MHC-I molecules. Recently, Salmonella bacteria we...
متن کاملCD4+ T cells regulate CD8+ T cell-mediated cutaneous immune responses by restricting effector T cell development through a Fas ligand-dependent mechanism.
The magnitude and duration of CD8(+) T cell-mediated responses in the skin to hapten sensitization and challenge, contact hypersensitivity (CHS), is negatively regulated by CD4(+) T cells through an unknown mechanism. In this study we show that CD4(+) T cells restrict the development and expansion of hapten-specific CD8(+) T cells mediating CHS responses to 2,4-dinitrofluorobenzene. In the abse...
متن کاملAnti-OX40 prevents effector T-cell accumulation and CD8+ T-cell mediated skin allograft rejection.
BACKGROUND OX40 is a member of the tumor necrosis factor receptor superfamily and is a potent T-cell costimulatory molecule. Although the impact of blockade of the OX40-OX40L pathway has been documented in models of autoimmune disease, the effect on allograft rejection is less well defined. METHODS The expression of OX40 and impact of OX40 blockade on BM3 T cells (H2Kb-reactive, T-cell recept...
