Question

Quizplus · Accepted Answer

Major histocompatibility complex (MHC) proteins are on the surface of most vertebrate cells and act as markers of "self" to the immune system. They present antigens to T cells and play a crucial role in immune recognition and response. T-cell receptors, antigens, and immunoglobulins are also involved in immune recognition and response, but are not specifically markers of "self" on the surface of cells.
