cytotoxic T cell

A CD8+ T lymphocyte that can destroy microorganisms directly through the release of perforin and proteolytic enzymes. These cells are particularly important in the defense against viruses, rejection of allografts, and, possibly, new malignant cells. Synonym: CD8 cell; cytotoxic cel; killer T cell

The article, entitled "Dendritic Cells Transduced with Full-Length Wild-Type p53 Generate Antitumor Cytotoxic T Lymphocytes from Peripheral Blood of Cancer Patients," indicated that dendritic cells treated with INGN 201 were able to induce a specific antitumor immune response mediated by cytotoxic T lymphocytes, or killer T cells.
That publication, as well as subsequent research, demonstrated that the RNA encoding the catalytic reverse transcriptase protein component of human telomerase (hTERT RNA), when introduced into dendritic cells, can stimulate the immune system to produce cytotoxic T lymphocytes (CTLs, or killer-T cells) capable of recognizing and destroying telomerase-positive cancer cells.
