Autoimmune inflammation, such as in rheumatoid arthritis, is characterized by activated Th1 cells without sufficient Th2 differentiation that might downmodulate the chronic immune response. Delineation of the mechanisms that control T-cell differentiation is therefore of major importance for the understanding of the pathogenesis of autoimmune diseases. The transcription factor GATA-3 has been implicated in regulating Th2 cell differentiation in murine T cells in vitro, but its role in vivo and, in particular, in human T-cell differentiation is currently unknown. To dissect the role of GATA-3 in human T-cell differentiation and T-cell-mediated effector functions, we used the unique opportuni…

Mild phenotypes in a series of patients with Opitz GBBB syndrome with MID1 mutations

Contains fulltext : 48815.pdf (Publisher’s version ) (Closed access) Opitz syndrome (OS; MIM 145410 and MIM 300000) is a congenital midline malformation syndrome characterized by hypertelorism, hypospadias, cleft lip/palate, laryngotracheoesophageal (LTE) abnormalities, imperforate anus, developmental delay, and cardiac defects. The X-linked form (XLOS) is caused by mutations in the MID1 gene, which encodes a microtubule-associated RBCC protein. In this study, phenotypic manifestations of patients with and without MID1 mutations were compared to determine genotype-phenotype correlations. We detected 10 novel mutations, 5 in familial cases, 2 in sporadic cases, and 3 in families for whom it …
