Histocompatibility antigen. Computer graphic of part of a human histocompatibility antigen,a pro- tein molecule that the immune system uses to rec- ognise the body's own cells. Seen here is the antigen binding site of a class 1 histocompatibil- ity antigen. Its parts are colour-coded: beta- pleated sheet (yellow); alpha helix (magenta); random coil (blue/white). There are several series in the main grouping of these antigens,which is known as the Human Leukocyte Antigen (HLA) system. The antigens' exact shapes are determined by the genes that a person inherits from their parents. ue transplants,which have "foreign" antigens | |
