Question

Cell-surface proteins on specialized antigen-presenting cells such as dendritic cells, which are the major co-stimulatory molecules for T cells. These cell surface proteins are closely related members of the immunoglobulin superfamily and both bind to the CD28 and CTLA-4 proteins on T cells

Accepted Answer
