ANATOMY

Detailed explanation-1: -The function of MHC molecules is to bind peptide fragments derived from pathogens and display them on the cell surface for recognition by the appropriate T cells.

Detailed explanation-2: -MHC markers or Major Histo-compatibility Complex, are proteins expressed on the surface of a cell. They are used primarily in the recognition of pathogens in immune responses. We can break MHC markers up into 2 types, MHC 1 and MHC 2.

Detailed explanation-3: -There are two major types of MHC protein molecules-class I and class II. Class I MHC molecules span the membrane of almost every cell in an organism, while class II molecules are restricted to cells of the immune system called macrophages and lymphocytes.

Detailed explanation-4: -The MHC II molecule then travels to the surface to present the antigen to a helper T cell. MHC II active helper T cells which help release cytokines and other things which will help induce other cells which help to combat the pathogens outside the cells.

Detailed explanation-5: -While MHC class I is ubiquitously expressed by almost all cells, MHC class II is mostly expressed by antigen-presenting cells (APCs) such as monocytes, macrophages, and dendritic cells.
