How do cytotoxic t cells recognize a pathogen
WebJan 17, 2024 · To control their cytotoxic activity, NK cells possess two types of surface receptors: activating receptors and inhibitory receptors. Most of these receptors are also present in certain T cells. These receptors recognize major histocompatability complex I (MHC I), a molecule expressed on every cell to signal that the cell belongs to the body.
