What HLA means?
HLA stands for human leukocyte antigens. HLA are proteins—or markers—on most cells in your body. Your immune system uses HLA to see which cells belong in your body and which do not.
What does the HLA gene do?
The HLA complex helps the immune system distinguish the body’s own proteins from proteins made by foreign invaders such as viruses and bacteria. HLA is the human version of the major histocompatibility complex (MHC), a gene family that occurs in many species.
What is the meaning of HLA?
human leukocyte antigen
Listen to pronunciation. (HYOO-mun LOO-koh-site AN-tih-jen) A type of molecule found on the surface of most cells in the body. Human leukocyte antigens play an important part in the body’s immune response to foreign substances.
Is HLA an antigen or gene?
The human leukocyte antigen (HLA) system or complex is a complex of genes on chromosome 6 in humans which encode cell-surface proteins responsible for the regulation of the immune system. The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals.
What does MHC stand for in immunology?
Major histocompatibility complex
Introduction. Major histocompatibility complex (MHC) class I and class II proteins play a pivotal role in the adaptive branch of the immune system. Both classes of proteins share the task of presenting peptides on the cell surface for recognition by T cells.
What is the role of HLA genes?
Where is MHC found?
MHC class I molecules are one of two primary classes of major histocompatibility complex (MHC) molecules (the other being MHC class II) and are found on the cell surface of all nucleated cells in the bodies of vertebrates. They also occur on platelets, but not on red blood cells.
What is MHC test?
A histocompatibility antigen blood test looks at proteins called human leukocyte antigens (HLAs). These are found on the surface of almost all cells in the human body. HLAs are found in large amounts on the surface of white blood cells.
How does HLA relate to MHC in immune physiology?
The human leukocyte antigen (HLA) system or complex is a group of related proteins that are encoded by the major histocompatibility complex (MHC) gene complex in humans. These cell-surface proteins are responsible for the regulation of the immune system. The HLA gene complex resides on a 3 Mbp stretch within chromosome 6, p-arm at 21.3.

What does MHC stand for?
The major histocompatibility complex (MHC) genes code for proteins which the immune system uses to identify cells and tissues in the body as “self” or “other”. MHC molecules ‘talk’ to T cells which patrol the body for foreign invaders or dangerously mutated cells. The MHC acts as a window into our cells.
