Chronic Inflammation - T Regulatory Cells (Lecture 4)

Chronic Inflammation - T Regulatory Cells (Lecture 4)

An important lecture in the chronic inflammation series. T Regulatory cells (TRegs) and their function. Let's review this promising area of immunology.

A good reference diagram in the book:
FIGURE 15.6   Mechanism of action of CTLA-4. A, Cytotoxic T lymphocyte antigen 4 (CTLA-4) expressed on regulatory T cells (Tregs) or activated T cells can inhibit the activation of responding T cells on the same antigen-presenting cells (APCs) (in trans). B, CTLA-4 on regulatory or activated T cells binds to B7 molecules on APCs and removes these molecules from the surface of the APCs, making the B7 costimulators unavailable to CD28 and blocking T cell activation. This action of CTLA-4 is able to suppress immune responses best when B7 levels are low, enabling CTLA-4 to out-compete the lower-affinity receptor CD28.
