a system of cell surface antigens which induce and regulate the immune response. HLAs are used to match body tissues for organ transplants.
HLA; the tissue typing test done on white cells to determine if a donor and recipient are compatible.
A distinguishing series of proteins that exist on the surface of every white blood cell to help the cells discriminate between “friendly” cells and “foreign” matter like bacteria and viruses. HLA “matching” plays a vital role in allogeneic, or unmatched, bone marrow and stem cell transplants.
A genetic fingerprint on white blood cells and platelets, composed of proteins that play a crucial role in activating the body's immune system to respond to foreign bodies. Also called HLA.
histocompatibility locus antigen .
A genetic fingerprint on white blood cells and platelets, made up of proteins that play a critical role in activating the body's immune system. If two individuals have indentical HLA types, they are said to be histocompatible.
a genetic marker of "self" which prevents the immune system from attacking the body's own tissues. Various HLA patterns are associated with (HLA)
any one of four significant genetic markers found on all nucleated cells of the body that determine white blood cell types. The HLA system is used to assess tissue compatibility for platelet and white blood cell transfusion and organ transplantation (approx.10,000 HLA types).
HLA. One of a group of proteins found on the surface of white blood cells and other cells that play an important part in the body's immune response to foreign substances. These antigens vary from person to person, and an HLA test is done before organ transplantation to find out if tissues match between a donor and a recipient. Also called human lymphocyte antigen.
a type of receptor on cells involved in recognising foreign antigens; some are associated with different types of arthritis
The human leukocyte antigen system (HLA) is the name of the human major histocompatibility complex (MHC). This group of genes resides on chromosome 6, and encodes cell-surface antigen-presenting proteins. The chance of two individuals having identical HLA molecules on all loci is very low, except for siblings, which have a 25% chance of being HLA-identical.
