What is the Major Histocompatibility Complex (MHC)?
The Major Histocompatibility Complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules. The MHC molecules display peptide fragments derived from pathogens, enabling T-cells to detect and initiate an immune response. MHCs are highly polymorphic, meaning they can present a vast array of peptides, aiding in immune surveillance.
