Question

Quizplus · Accepted Answer

Blocking the CD4 receptor on helper T lymphocytes may inhibit activation by antigen presenting cells. CD4 is a co-receptor that helps bind the T cell receptor (TCR) to the major histocompatibility complex (MHC) on antigen presenting cells, thus facilitating T cell activation. Inhibiting CD4-TCR-MHC interaction can prevent T cell activation and subsequent immune response. CD25 is the IL-2 receptor alpha subunit, MHC is the molecule that presents antigens to TCR, and IL-6 is a cytokine involved in inflammation and immune regulation but not directly involved in T cell activation by antigen presenting cells.
