Final answer:
d) MHC class II. CD8+ T cells do not require co-stimulation to perform effector functions. MHC class II molecules are typically involved in the activation of CD4+ T cells (helper T cells). They are able to recognize antigens presented in association with MHC I without the need for additional signals.
Step-by-step explanation:
Once activated, CD8+ T cells do not require Co-stimulation to perform effector functions. They are able to recognize antigens presented in association with MHC I without the need for additional signals. They are able to recognize antigens presented in association with MHC I without the need for additional signals. CD8+ T cells can directly kill infected cells or secrete cytokines to activate other immune cells.
Once activated, CD8+ T cells do not require MHC class II molecules to perform effector functions. CD8+ T cells are cytotoxic T cells that recognize antigens presented on MHC class I molecules. After activation, CD8+ T cells primarily interact with target cells presenting antigens on MHC class I. MHC class II molecules are typically involved in the activation of CD4+ T cells (helper T cells). They are able to recognize antigens presented in association with MHC I without the need for additional signals. CD8+ T cells can directly kill infected cells or secrete cytokines to activate other immune cells. Co-stimulation, antigen recognition, and cytokines are essential for the activation and function of CD8+ T cells.
