cytotoxic T cell

[¦sīd·ə‚täk·sik ′tē ‚sel]
(immunology)
A type of T cell which protects against pathogens that invade host cell cytoplasm, where they cannot be bound by antibodies, by recognizing and killing the host cell before the pathogens can proliferate and escape.

Prior research has demonstrated that CD4 and CD8 T cells are both important in cellular immune responses; however, CD8 T-cells, or killer T cells, are considered especially integral to fighting cancers and chronic infectious diseases.
TAT0002 was previously shown to stimulate the production of IFN-gamma -- a molecule involved in the anti-viral response of cytotoxic CD8 T-cells specific for the HIV-1 AIDS virus -- and to enhance the ability of the CD8 cells to proliferate and kill HIV-1-infected CD4 cells.
a joint venture between Geron Corporation and the Biotechnology Research Corporation of Hong Kong (BRC), announced today the presentation of studies demonstrating that their small molecule telomerase activator, TAT0002, enhances the anti-viral activity of CD8 T-cells from HIV/AIDS donors against infected CD4 cells from the same donors.
Recent clinical data from other WT1 peptide immunotherapeutics stimulating CD8 T-cells has been very positive.
