The Critical Need for CD4 Help in Maintaining Effective Cytotoxic T Lymphocyte Responses
F or many viral infections, resolution of illness is associated with long-term host control of viremia rather than viral eradication. An example is EBV infection, and the fact that host immune suppression is associated with EBV-induced disease suggests that it is the immune system that is holding the virus in check (1, 2). Other viruses are typically associated with progressive uncontrolled dis...
متن کاملCRTAM determines the CD4+ cytotoxic T lymphocyte lineage
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 ...
متن کاملVaccinia virus-specific human CD4+ cytotoxic T-lymphocyte clones.
Vaccinia virus-specific cytotoxic T-lymphocyte (CTL) clones were established from a healthy donor, who had been immunized with vaccinia virus vaccine, by stimulation of peripheral blood lymphocytes with UV-inactivated vaccinia virus antigen. The phenotype of all of the clones established was CD3+ CD4+ CD8- Leu11-. We used a panel of allogenic vaccinia virus-infected B-lymphoblastoid cell lines ...
متن کاملT Lymphocyte Differentiation as a Mechanism for Subdominant Cytotoxic T Lymphocyte Responses to a Viral Antigen
CD8 1 cytotoxic T lymphocytes (CTLs) recognize antigen in the context of major histocompatibility complex (MHC) class I molecules. Class I epitopes have been classified as dominant or subdominant depending on the magnitude of the CTL response to the epitope. In this report, we have examined the in vitro memory CTL response of H-2 d haplotype murine CD8 1 T lymphocytes specific for a dominant an...
متن کاملInduction of a CD8+ Cytotoxic T Lymphocyte Response by Cross-priming Requires Cognate CD4+ T Cell Help
Class I-restricted presentation is usually associated with cytoplasmic degradation of cellular proteins and is often considered inaccessible to exogenous antigens. Nonetheless, certain exogenous elements can gain entry into this so-called endogenous pathway by a mechanism termed cross-presentation. This is known to be effective for class I-restricted cytotoxic T lymphocyte (CTL) cross-priming d...
