Most cytotoxic T cells express T-cell receptors (TCRs) that can recognize a specific antigen. [4] T cells possess a wide functional plasticity after recognising infected or transformed cells, as they are able to produce cytokines (IFN-, TNF-, IL-17) and chemokines (IP-10, lymphotactin), trigger cytolysis of target cells (perforins, granzymes), and interact with other cells, such as epithelial cells, monocytes, dendritic cells, neutrophils and B cells.
