Overview
The Human Leukocyte Antigen (HLA) system is a complex of genes on chromosome 6 that encode cell-surface proteins responsible for regulating the immune system. With over 12,000 known alleles, the HLA system is highly polymorphic, allowing it to fine-tune the adaptive immune system. Specific HLA genes have been linked to autoimmune diseases such as type I diabetes and celiac disease, and the system plays a crucial role in organ transplantation. The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. Research on HLA has been conducted by renowned scientists such as Janeway Charles Aldfred and Peter Parham, and has been published in prominent journals like Nature and Science. The HLA system has been studied in the context of various diseases, including type 1 diabetes and celiac disease, and has been found to have a significant impact on the outcome of organ transplantation.
🎵 Origins & History
The Human Leukocyte Antigen (HLA) system has a rich history, dating back to the 1950s when it was first discovered by Jean Dausset. The HLA system was initially identified as a factor in organ transplantation, and later found to play a crucial role in the immune system. The system is located on chromosome 6, p-arm at 21.3, and spans a 3 Mbp stretch. The HLA gene complex is highly polymorphic, with over 12,000 known alleles, allowing it to fine-tune the adaptive immune system. Research on HLA has been conducted by prominent institutions such as the National Institutes of Health and the Wellcome Trust.
⚙️ How It Works
The HLA system works by presenting peptides from inside the cell to the immune system. For example, if the cell is infected by a virus, the HLA system brings fragments of the virus to the surface of the cell, where they can be recognized by the immune system. The HLA system is divided into two main classes: MHC class I (A, B, and C) and MHC class II (DP, DQ, and DR). The proteins encoded by certain genes are also known as antigens, as a result of their historic discovery as factors in organ transplants. The HLA system has been studied in the context of various diseases, including HIV and cancer, and has been found to have a significant impact on the outcome of immunotherapy.
