WebHelper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, … WebCD4+ T helper (Th) cells interact with CD8+ T cells, which drive the cytotoxic response that kills cells infected with the virus. The CD8+ T cells directly recognize viral peptides presented at the surfaces of infected cells, causing apoptosis (a form of programmed cell death) and preventing the virus from spreading further.
