An MHC class II/antigen complex on the surface of an antigen-presenting cell (APC) binds to a T-cell receptor. What results from this interaction?
A) Other immune cells are inhibited.
B) The antigen is phagocytized by the T cell.
C) The T cell responds by directly destroying the APC.
D) Other immune cells are stimulated to respond to the antigen.
MHC Class II
Molecules present on immune cells that present antigens to helper T cells, crucial for initiating immune responses.
Antigen-Presenting Cell
A cell that displays antigen complexed with major histocompatibility complexes on their surfaces for recognition by T-cells.
T-Cell Receptor
A molecule found on the surface of T cells that is responsible for recognizing fragments of antigens as peptides bound to major histocompatibility complex (MHC) molecules.
