Learn about cytotoxic T cells, also referred to as CD8+ T cells, including cell activation, differentiation, and function in adaptive immune response.
A thymus-derived lymphocyte that is directly involved in cell-mediated immunity. These cells circulate in search of target cells to interact with and to neutralize at the site. Respiratory InfectionsSpringer Berlin HeidelbergEncyclopedic Reference of Immunotoxicology...
Activated CTLs secrete cytokines and can kill target cells expressing the same MHC/antigen complex. Since, with a few exceptions, all nucleated cells express MHC class I, the role of CTL is to monitor all the cells of the body, ready to destroy any that express foreign antigen fragments in...
The functions of, and interactions between, the innate and adaptive immune systems are vital for anticancer immunity. Cytotoxic T cells expressing cell-surface CD8 are the most powerful effectors in the anticancer immune response and form the backbone of

Cells were combined at a plated E/T of 25:1. True E/T ratios were derived from parallel measurements of the frequencies of HIV-specific CD8+ T cells based on IFN-γ production (true effector cell numbers) and the percentages of HIV p24+ T-cell targets (true target cell numbers). To ...
We are interested in the dominant Vγ2Vδ2+ T cell subset in human peripheral blood and the control of effector function in this population. We review the literature on γδ T cell generation and repertoire selection, along with ... H Tcells,EM Urban,AI Chapoval,... 被引量: 0发表:...
Thus, CD8 + T cells are needed to be primed and activated toward effector CTLs in a process called tumor immunity cycle for making durable and efficient antitumor immune responses. The CD8 + T cell priming is directed essentially as a corroboration work between cells of innate immunity ...

Second, we sought to identify the subtypes of CD8+T cells and NK cells in MIS-C by projecting subtype-specific cell signatures onto skyblue (Fig.1g). Functional classes of CD8+T cells that emerge following viral infection include effector, memory, and exhausted subtypes (Teff, Tmem, and Tex...
