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.

Compared with the control patients, those in the STI group had significantly lower viral loads, higher CD4-positive T-cell counts, lower values of immune activation markers, and higher specific helper and cytotoxic T-lymphocyte responses against HIV.
The study results showed that co-administration of PT-100 with a cytotoxic T-Lymphocyte (CTL) peptide antigen and a T-cell helper peptide, administered either orally or intranasally, induced robust T cell responses which were dose dependent on PT-100.
Geron had previously shown in collaboration with researchers at Duke University that RNA encoding hTERT could be used to prime antigen presenting cells (DCs) ex vivo, and that these cells in turn could stimulate a potent, telomerase-specific cytotoxic T-lymphocyte (CTL) response.
No other vaccine technology demonstrated to date has shown itself capable of inducing strong natural production of both highly specific neutralizing antibodies and a potent cytotoxic T-lymphocyte (CTL) or cellular immune responses.
