A study in rats revealed that a specific microRNA, called miR-23b-3p, acts as a natural brake on an overactive immune response in a blood vessel inflammation disease (IgA vasculitis). Restoring levels of this molecule reduced disease symptoms, pointing to a promising new strategy for treating similar autoimmune and inflammatory disorders.
