Question

Quizplus · Accepted Answer

The major histocompatibility complex (MHC) is a group of genes that encode proteins on the surface of cells that are important for immune recognition. T-cells recognize these MHC proteins and use them to distinguish between self and nonself. This is important in preventing the immune system from attacking the body's own cells and tissues. While T-cells can recognize specific bacteria, viruses, and parasites, it is the MHC that allows them to recognize whether these pathogens are foreign and should be attacked or part of self and should be ignored.
