Major histocompatibility complex class II (MHCII) antigen expression is usually directly correlated with immunogenicity, and inversely correlated with tumorigenicity, in clones of the L1210 murine B lymphoma. activate T cells. The costimulatory molecules B7-1, B7-2 and CD40 were expressed around the immunogenic L1210 clones, but not the tumorigenic clones. Importantly, the tumour-forming subclonal variants expressed… Continue reading Major histocompatibility complex class II (MHCII) antigen expression is usually directly
