Question

Quizplus · Accepted Answer

T cells express unique T cell receptors (TCRs) on their surface that are responsible for recognizing and binding to antigenic peptides presented on major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells. This binding initiates a signaling cascade that ultimately leads to T cell activation and the initiation of an immune response. Antigen recognition by TCRs is crucial for the development of effective adaptive immune responses against a wide range of pathogens and tumors.
