Question

Quizplus · Accepted Answer

The CD8 receptor is found on cytotoxic T lymphocytes and is responsible for recognizing and binding to MHC class I molecules on infected or abnormal cells. Helper T lymphocytes have the CD4 receptor and recognize MHC class II molecules on antigen-presenting cells. Therefore, the CD8 receptor is the receptor that differentiates cytotoxic T lymphocytes from helper T lymphocytes. MHC class I and the T cell receptor are both involved in antigen recognition but are not specific to either cytotoxic or helper T cells. The B cell receptor is specific to B lymphocytes and is not involved in T cell differentiation.
