Major Locus Antigen

The main locus antigen (English: HLA-antigen) is one of the most important elements of the human immune system, which is involved in protecting the body from various infections and diseases. This antigen is found on the surface of blood cells and helps the immune system recognize foreign substances such as bacteria, viruses and even cancer cells.

The main component of the HLA system is the Major Locus (English: Major Histocompatibility Complex, MHC), which consists of more than 260 genes. These genes are responsible for the production of molecules called HLA antigens, which perform the function of recognizing and marking antigens on cells. Important characteristics of these antigens are their ability to bind to helper T cells in the immune system and induce an immune response.

The presence of certain HLA genes can lead to
