HLA system

n
(Biochemistry) human leucocyte antigen system; a group of the most important antigens responsible for tissue compatibility, together with the genes that encode them. For tissue and organ transplantation to be successful there needs to be a minimum number of HLA differences between the donor's and recipient's tissue

The high polymorphism of the HLA system and advancements in molecular biology have permitted for the typifying of these antigens to become important tools in establishing associations of susceptibility or resistance to disease, development of tumor processes; playing an important role in understanding the variability of the immune response and determinant on the survival of organ or tissue transplants (2-8).
