Cytotoxic T cells kill infected target body cells much like natural killer cells do. The major difference is: -cytotoxic T cells have receptors specific for a particular microbe and thus kill only target body cells infected with one particular type of microbe.Click to see full answer.

Cytotoxic T cells kill infected target body cells much like natural killer cells do. The major difference is: -cytotoxic T cells have receptors specific for a particular microbe and thus kill only target body cells infected with one particular type of microbe.Click to see full answer. Simply so, what is the mode of action of T cytotoxic cells?mechanism of cell-mediated immunity involves cytotoxic T cells. They attach themselves by their receptors to target cells whose surface expresses appropriate antigens (notably ones made by developing viruses) and damage the infected cells enough to kill them.Beside above, how do cytotoxic T cells kill infected target cells quizlet? CD8 and CD4 are co-receptor proteins that help T cells recognize their target cells. How do cytotoxic T cells kill their target cells? – Cytotoxic T cells release perforin which pokes holes in the cell’s plasma membrane. – T cells release enzymes called granzymes that induce target cells to undergo apoptosis. Secondly, what is the role of cytotoxic T cells and describe their mechanism of action? A type of lymphocyte that kills infected cells, cancer cells, and transplanted cells when activated. Dendritic cells, macrophages, and B cells. Named for key role in displaying such internalized antigens to helper T cells.How do you activate T cells? Helper CD4+ T cells Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
