Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling

aledopress

Central tolerance of thymocytes to self-antigen depends on the medullary thymic epithelial cell (mTEC) transcription factor autoimmune regulator (Aire), which drives tissue-restricted antigen (TRA) gene expression. Vitamin D signaling regulates Aire and TRA expression in mTECs, providing a basis for links between vitamin D deficiency and autoimmunity. We find that mice lacking Cyp27b1, which cannot… Continue reading Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling

Effect of #Ergocalciferol on β-Cell Function in New-Onset Type 1 #Diabetes A Secondary Analysis of a Randomized Clinical Trial

aledopress

IntroductionApproximately 30% to 50% residual β-cell function may remain at the time of type 1 diabetes (T1D) diagnosis, and this may persist for months or years.1,2 A prolonged partial remission (PR) phase of T1D leads to improved glycemic control and decreased long-term complications.1 We previously reported1 that ergocalciferol significantly decreased circulating tumor necrosis factor (TNF)-α and temporal trends… Continue reading Effect of #Ergocalciferol on β-Cell Function in New-Onset Type 1 #Diabetes A Secondary Analysis of a Randomized Clinical Trial
