Mixed connective tissue disease (MCTD) is a systemic autoimmune disease, originally defined as a connective tissue inflammatory syndrome with overlapping features of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), polymyositis/dermatomyositis (PM/DM) and systemic sclerosis (SSc), characterized by the presence of antibodies against components of the U1 small nuclear ribonucleoprotein...
We characterized 549 new human leukocyte antigen (HLA) class I and class II alleles found in newly registered stem cell donors as a result of high‐throughput HLA typing. New alleles include 101 HLA‐A, 132 HLA‐B, 105 HLA‐C, 2 HLA‐DRB1, 89 HLA‐DQB1 and 120 HLA‐DPB1 alleles. Mainly, new alleles comprised single nucleotide variations when compared with homologous sequences. We identified nonsynonymous...
Genes from the HLA complex have a major contribution in type 1 diabetes (T1D), which results from an interplay between environmental and genetic factors. The latter can explain some of the geographic variability in T1D occurrence around the world. Of a particular importance in this regard are the HLA‐DR, ‐DP and ‐DQ loci. Consequently, we aimed at elucidating the collective genetic profiles of various...
Innate lymphoid cells (ILCs) are a new class of immune cells that include natural killer (NK) cells and appear to be the innate counterparts to CD4+ helper T cells and CD8+ cytotoxic T cells based on developmental and functional similarities. Like T cells, both NK cells and other ILCs also show connections to the major histocompatibility complex (MHC). In human and mouse, NK cells recognize and respond...
Immunogenetic studies have suggested that autoantibody production is commonly associated with particular human leukocyte antigens (HLA) class II genotypes in certain autoimmune diseases. The objective of this study was to investigate whether the production of anti‐β2‐glycoprotein I antibody (aβ2GPI) was associated with particular HLA‐DQ alleles in patients with recurrent miscarriage (RM). The HLA‐DQ...
