Yiguanjian alleviates ocular surface inflammation and lacrimal gland immune dysregulation in experimental dry eye disease: evidence from in vivo and in vitro models
Background Persistent ocular surface inflammation and lacrimal gland immune dysregulation are central to the progression of dry eye disease (DED). Th17/Treg imbalance contributes to sustained inflammatory activation in the ocular surface and lacrimal gland. Yiguanjian (YGJ) has anti-inflammatory and immunomodulatory po...
