Disease
DRB1_HUMAN Giant cell arteritis;NON RARE IN EUROPE: Rheumatoid arthritis;Narcolepsy type 1;Pediatric multiple sclerosis;Sarcoidosis;Systemic lupus erythematosus;Systemic-onset juvenile idiopathic arthritis;Autoimmune pulmonary alveolar proteinosis;Limited systemic sclerosis;Limited cutaneous systemic sclerosis;Diffuse cutaneous systemic sclerosis;NON RARE IN EUROPE: Multiple sclerosis;Follicular lymphoma;Bullous pemphigoid;NON RARE IN EUROPE: Celiac disease;Narcolepsy type 2. In populations of European descent, allele DRB1*01:03 is associated with increased susceptibility to Crohn disease and colonic ulcerative colitis. Decreased heterozygosity in individuals with colonic ulcerative colitis suggests that it acts as a recessive risk allele.[1] Disease susceptibility is associated with variants affecting the gene represented in this entry. Alleles DRB1*04:02, DRB1*11:01 and DRB1*12:01 are associated with sarcoidosis. Allele DRB1*04:02 is significantly associated with specific sarcodosis phenotypes such as eye, parotid and salivary gland involvement.[2] Disease susceptibility is associated with variants affecting the gene represented in this entry. In populations of European descent, allele DRB1*15:01 has the strongest association with multiple sclerosis among all HLA class II alleles. Additional risk is associated with the strongly linked alleles DRB1*03:01 and DQB1*02:01 as well as with allele DRB1*13:03 (PubMed:21833088). It is postulated that bacterial or viral infection triggers the autoimmune MS. Microbial peptides having low affinity crossreactivity to MBP autoantigen, may stimulate autoreactive T cells via molecular mimicry and initiate the autoimmune inflammation (PubMed:19303388).[3] [4] Allele DRB1*15:01 is associated with increased susceptibility to Goodpasture syndrome. Can present a self-peptide derived from COL4A3 (GWISLWKGFSF) on TCR (TRAV19 biased) in pathogenic CD4-positive T-helper 1 and T-helper 17 cells, triggering autoimmune inflammation.[5] Disease susceptibility is associated with variants affecting the gene represented in this entry. Alleles DRB1*04:01; DRB1*04:04; DRB1*04:05; DRB1*04:08; DRB1*10:01; DRB1*01:01 and DRB1*01:02 are associated with increased susceptibility to rheumatoid arthritis, where affected individuals have antibodies to cyclic citrullinated peptide (anti-CCP-positive rheumatoid arthritis). Variations at position 40 in the peptide-binding cleft of these alleles explain most of the association to rheumatoid arthritis risk.[6]
Function
DRB1_HUMAN A beta chain of antigen-presenting major histocompatibility complex class II (MHCII) molecule. In complex with the alpha chain HLA-DRA, displays antigenic peptides on professional antigen presenting cells (APCs) for recognition by alpha-beta T cell receptor (TCR) on HLA-DRB1-restricted CD4-positive T cells. This guides antigen-specific T-helper effector functions, both antibody-mediated immune response and macrophage activation, to ultimately eliminate the infectious agents and transformed cells (PubMed:15265931, PubMed:16148104, PubMed:22327072, PubMed:27591323, PubMed:29884618, PubMed:31495665, PubMed:8642306). Typically presents extracellular peptide antigens of 10 to 30 amino acids that arise from proteolysis of endocytosed antigens in lysosomes (PubMed:8145819). In the tumor microenvironment, presents antigenic peptides that are primarily generated in tumor-resident APCs likely via phagocytosis of apoptotic tumor cells or macropinocytosis of secreted tumor proteins (PubMed:31495665). Presents peptides derived from intracellular proteins that are trapped in autolysosomes after macroautophagy, a mechanism especially relevant for T cell selection in the thymus and central immune tolerance (PubMed:17182262, PubMed:23783831). The selection of the immunodominant epitopes follows two processing modes: 'bind first, cut/trim later' for pathogen-derived antigenic peptides and 'cut first, bind later' for autoantigens/self-peptides (PubMed:25413013). The anchor residue at position 1 of the peptide N-terminus, usually a large hydrophobic residue, is essential for high affinity interaction with MHCII molecules (PubMed:8145819).[7] [8] [9] [10] [11] [12] [13] [14] [15] [16] Allele DRB1*01:01: Displays an immunodominant epitope derived from Bacillus anthracis pagA/protective antigen, PA (KLPLYISNPNYKVNVYAVT), to both naive and PA-specific memory CD4-positive T cells (PubMed:22327072).

Displays commonly recognized peptides derived from IAV external protein HA (PKYVKQNTLKLAT and SNGNFIAPEYAYKIVK) and from internal proteins M, NP and PB1, with M-derived epitope (GLIYNRMGAVTTEV) being the most immunogenic (PubMed:25413013, PubMed:32668259, PubMed:8145819, PubMed:9075930). Presents a self-peptide derived from COL4A3 (GWISLWKGFSF) to TCR (TRAV14 biased) on CD4-positive, FOXP3-positive regulatory T cells and mediates immune tolerance to self (PubMed:28467828). May present peptides derived from oncofetal trophoblast glycoprotein TPBG 5T4, known to be recognized by both T-helper 1 and regulatory T cells (PubMed:31619516).

Publication Abstract from PubMed
Class II proteins of the major histocompatibility complex (MHCII) typically present exogenous antigenic peptides to cognate T cell receptors of T lymphocytes. The exact conformation of peptide-MHCII complexes (pMHCII) can vary depending on the length, register and orientation of the bound peptide. We have recently found the self-peptide CLIP (class-II-associated invariant chain-derived peptide) to adopt a dynamic bidirectional binding mode with regard to the human MHCII HLA-DR1 (HLA, human leukocyte antigen). We suggested that inversely bound peptides could activate specific T cell clones in the context of autoimmunity. As a first step to prove this hypothesis, pMHC complexes restricted to either the canonical or the inverted peptide orientation have to be constructed. Here, we show that genetically encoded linkage of CLIP and two other antigenic peptides to the HLA-DR1 alpha-chain results in stable complexes with inversely bound ligands. Two-dimensional NMR and biophysical analyses indicate that the CLIP-bound pMHC(inv) complex (pMHC(inv), inverted MHCII-peptide complex) displays high thermodynamic stability but still allows for the exchange against higher-affinity viral antigen. Complemented by comparable data on a corresponding beta-chain-fused canonical HLA-DR1/CLIP complex, we further show that linkage of CLIP leads to a binding mode exactly the same as that of the corresponding unlinked constructs. We suggest that our approach constitutes a general strategy to create pMHC(inv) complexes. Such engineering is needed to create orientation-specific antibodies and raise T cells to study phenomena of autoimmunity caused by isomeric pMHCs.
