So these cytotoxic T cells contain special T cell receptors along with a CDA Glycoprotein that is needed to bind to the MHC Class One complex. So let's take a look at the following diagram to see what the mechanism is by which the cytotoxic T cell actually kills off and finds finds and kills off that cancer cell. So we have normal cells of our body that display the normal cell antigen shown in green on that MHC class One complex. And we have this cancer cell that still has the MHC class One complex. Remember, not all cancer cells actually destroy the MHC Class One complex. Some of them still actually have them.
