MHC molecules also play an important role in the presentation of foreign antigens, which is a critical step in the activation of T cells and thus an important mechanism of the adaptive immune system.

It emphasizes that APCs inform the immune system about cell health. Dendritic cells specifically phagocytose pathogens and present antigens, facilitating the activation of CD8 T cells through cross-presentation with MHC I, even without direct infection.
