This study explores the potential of statins as an adjunct treatment for alopecia areata (AA) by targeting the pathogenic interactions between MICA and NKG2D, which are not addressed by JAK inhibitors. The research involved co-culturing human outer root sheath keratinocytes with Vd1+T cells to simulate AA conditions. Findings indicate that oxidative stress increases MICA expression, leading to immune privilege collapse in hair follicles. Lovastatin treatment counteracts this by up-regulating ADAM10 and 17, enhancing MICA shedding, and potentially suppressing harmful MICA-NKG2D interactions. The results suggest that statins could be a promising addition to AA management strategies.
