CD antigens are
A) found on B cells, where they determine the antibody types that are made.
B) found on B cells, where they make recognition of self antigens on macrophages possible.
C) found on T cells, which they enable to recognized foreign antigens on macrophages.
D) found on macrophages, which they enable to link with both B and T cells.
E) found on bacteria that cause infection, enabling the immune system to recognize them.

Question

Quizplus · Accepted Answer

CD antigens are proteins found on the surface of immune cells, including T cells, B cells, and macrophages. They play a role in immune cell activation and communication. CD4 and CD8 are examples of CD antigens found on T cells, which enable them to recognize foreign antigens on macrophages and other antigen-presenting cells. CD19 is an example of a CD antigen found on B cells, which is involved in B cell signaling and activation. Therefore, option C is correct as it describes the function of CD antigens on T cells.
