The costimulatory molecule CD28 augments the T cell receptor activating signals, while CD3 is the part of the TCR that transfers activation signals into the cell to trigger the proliferation and differentiation of the activated T cell. Nettet9. mai 2024 · Cytotoxic T cells (AKA ‘killer’ T cells) are key lymphocytes of the adaptive immune system. Like helper T cells, they are activated by antigen-presenting cells in the lymph nodes. However, whereas helper T cells mediate the activity of other immune cells against a pathogen, cytotoxic T cells directly attack and destroy infected host cells. eye doctor shop
