research Epigallocatechin-3 Gallate Inhibits STAT-1/JAK2/IRF-1/HLA-DR/HLA-B and Reduces CD8 MKG2D Lymphocytes of Alopecia Areata Patients
This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.
