WebOct 23, 2024 · In a mouse tumour model, immunotherapy-induced rejection of tumour cells requires presentation of both MHC class I and MHC class II antigens, which activate CD4+ and CD8+ T cells, respectively. WebOct 13, 2013 · MHC II are the special molecules that are only expressed in antigen-presenting cells, which I think is what you are referring to. As neither CD4 or CD8 T-cells present antigens, they do not express MHC-II themselves. Instead CD4 have receptors for MHCII (while CD8 have receptors for MHCI), allowing them to interact with antigens …
