Exploring the effect of hsa-miR-19b-3p on IL-1R1 expression and serum levels in alopecia areata

The study explores the impact of hsa-miR-19b-3p on IL-1R1 expression in alopecia areata (AA), involving 100 AA patients and 100 healthy controls. It found that AA patients had significantly higher serum IL-1R1, IL-1R1 gene expression, and hsa-miR-19b-3p levels, with the most severe cases showing the highest levels. These markers were strongly correlated, suggesting that elevated IL-1R1 and hsa-miR-19b-3p could be used as diagnostic and prognostic indicators for AA, highlighting potential molecular targets for future therapies.
