MHC class I molecules including HLA-A and HLA-B are proteins integral to the immune system. They often refer to as HLA which stands for Human Leukocyte Antigens. Typically MHC class I proteins with a molecular mass of around 45 kDa are expressed on the surface of nearly all nucleated cells. Their main mechanical function is to present endogenous peptides to CD8+ cytotoxic T lymphocytes enabling the immune system to monitor and respond to intracellular changes such as infections or malignancies.
Biological function summary
These MHC molecules play a critical role in adaptive immunity. They form a complex with beta-2 microglobulin (β2m) to achieve stability and function properly on cell surfaces. HLA-A and HLA-B bind to short peptides derived from intracellular proteins which are then transported through the endoplasmic reticulum. The peptide-MHC complex is then expressed on the cell surface where it facilitates recognition by T cell receptors guiding immune responses against infected or transformed cells.
Pathways
MHC class I molecules are deeply involved in the antigen processing and presentation pathway as well as the immune effector process. In the antigen processing pathway proteins within the cell undergo degradation by the proteasome creating peptide fragments. These fragments are transported into the endoplasmic reticulum by the TAP (transporter associated with antigen processing) proteins where they bind with MHC class I forming a stable complex. Proteins like TAP and proteasome subunits work closely with MHC class I to ensure proper immune surveillance.
Dysregulation or alterations in MHC class I molecules particularly HLA-A and HLA-B have been linked to autoimmune diseases and cancers. For instance specific HLA alleles associate with autoimmune conditions like Type 1 Diabetes where the immune system erroneously targets pancreatic cells. In cancers a downregulation of MHC class I molecules often occurs as a mechanism to evade immune detection. Altered expression of proteins like TAP can also disrupt antigen presentation contributing to the disease onset and progression.
