The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2] Mutations in HLA genes may be linked to ...
The discovery of the MHC and role of histocompatibility in transplantation was a combined effort of many scientists in the 20th century. A genetic basis for transplantation rejection was proposed in a 1914 Nature paper by C.C. Little and Ernest Tyyzer, which showed that tumors transplanted between genetically identical mice grew normally, but tumors transplanted between non-identical mice were ...
DR5 is associated with persistent generalized lymphadenopathy [3] and Kaposi's sarcoma in AIDS, [4] juvenile rheumatoid arthritis, [5] [6] pernicious anemia, Hashimoto's thyroiditis, [7] [8] mycosis fungoides, [9] polyglandular deficiency syndrome, [10] systemic sclerosis, [11] [12] childhood epilepsy, [13] early-onset alopecia areata, [14] short-ragweed Ra6 allergy, [15] primary ...
HLA-DR is an MHC class II cell surface receptor encoded by the human leukocyte antigen complex on chromosome 6 region 6p21.31. The complex of HLA-DR (Human Leukocyte Antigen – DR isotype) and peptide, generally between 9 and 30 amino acids in length, constitutes a ligand for the T-cell receptor (TCR).

HLA-DP is a protein/peptide-antigen receptor and graft-versus-host disease antigen that is composed of 2 subunits, DPα and DPβ. DPα and DPβ are encoded by two loci, HLA-DPA1 and HLA-DPB1, that are found in the MHC Class II (or HLA-D) region in the Human Leukocyte Antigen complex on human chromosome 6 (see protein boxes on right for links).
HLA-B49 (B49) is an HLA-B serotype. B49 is a split antigen from the B21 broad antigen , the sister serotype B50 . [ 1 ] The serotype identifies the more common HLA-B*50 gene products. [ 2 ] (
The Georgia Cryptologic Center (GCC) or NSA Georgia is a U.S. National Security Agency (NSA) and Central Security Service (CSS) facility located within Fort Eisenhower, located outside of Augusta, Georgia. The 604,000 sq ft (56,100 m 2) facility opened on March 5, 2012, at a cost of $286 million.
