T-bet and GATA3 regulate the CD4+ T cell Th1/Th2 fate decision but little is known about interplay between these factors outside of murine Ifng Il4/Il5/Il13 loci. Here we show that bind to multiple distal sites at immune regulatory genes in human effector cells. These display markers functional elements, act as enhancers reporter assays are associated with a requirement for GATA3. Furthermore, demonstrate both Tbx21 directly activates its own expression. We also Th1 cells, distributed away...

Mice lacking the transcription factor T-bet in innate immune system develop microbiota-dependent colitis. Here, we show that interleukin-17A (IL-17A)-producing IL-7Rα+ lymphoid cells (ILCs) were potent promoters of disease Tbx21−/−Rag2−/− ulcerative colitis (TRUC) mice. TNF-α produced by CD103−CD11b+ dendritic synergized with IL-23 to drive IL-17A production ILCs, demonstrating a previously unrecognized layer cellular crosstalk between and ILCs. We have identified Helicobacter typhlonius as...

Tregs play a fundamental role in immune tolerance via control of self-reactive effector T cells (Teffs). This function is dependent on maintenance high intracellular cAMP concentration. A number microRNAs are implicated the Tregs. In this study, we demonstrate that peripheral critically posttranscriptional repression cAMP-hydrolyzing enzyme phosphodiesterase-3b (Pde3b) by microRNA-142-5p (miR-142-5p). manner, miR-142-5p acts as an immunometabolic regulator cAMP, controlling Treg suppressive...

The complex relationship between Th1 and Th17 cells is incompletely understood. transcription factor T-bet best known as the master regulator of lineage commitment. However, attention now focused on repression alternate T cell subsets mediated by T-bet, particularly lineage. It has recently been suggested that pathogenic express are dependent IL-23. previously shown to be a negative cells. We have taken an unbiased approach determine functional impact Genome-wide analysis binding sites...

The objective of this study was to determine the fitness Quadratic, Cubic, Gompertz and Logistic functions growth curves Konya Merino lambs obtained by using monthly records live weight from birth 480 days age. models were evaluated according determination coefficient (R2), mean square prediction errors (MSPE) Durbin Watson (DW) statistics. R2 values ranged 0.96 0.99 for females males. Cubic model gave best value in females, while lowest females. results indicated that Quadratic showed fit...

We report a case of severe hypercalcaemia secondary to rhabdomyolysis in woman with COVID-19 (SARS CoV-2) infection. The patient presented myalgia and anuria an acute kidney injury requiring haemodialysis. Creatine kinase peaked at 760 000 IU/L. A biphasic calcaemic response was observed initial hypocalcaemia followed by severe, symptomatic hypercalcaemia, persistent despite Control the calcium levels achieved continuous haemofiltration.

Genetically determined hypoparathyroidism can lead to life-threatening episodes of hypocalcemia and, more rarely, end-stage kidney disease at a young age. Parathyroid allotransplantation is the only curative treatment, and in patients already receiving immunosuppression for transplantation, there may be little additional risk involved. We report first such case child.An 11-y-old girl, known have secondary an activating pathogenic variant calcium-sensing receptor, developed was started on...
