Cytotoxic t-lymphocytes recognize
WebCytotoxic T lymphocytes (CTL) recognize surface markers on other cells in the body that label those cells for destruction. In this way, CTLs help to keep virus-infected or malignant cells in check. In the video above, the smaller CTL is attacking and killing a much larger influenza virus-infected target. WebProtective immunity to viruses is mediated primarily by cytotoxic T lymphocytes, which recognize viral peptides of 8-11 amino acids bound to major histocompatibility complex class I molecules on the surface of infected cells.
