新研究显示干眼症与泪腺细胞自噬机制紊乱有关

Core Viewpoint - An international study has discovered that disruption of the autophagy mechanism in tear glands can lead to abnormal tear secretion, which may be a significant cause of dry eye syndrome, providing new insights for treatment [1] Group 1: Research Findings - The study indicates that the autophagy mechanism in tear glands is crucial for destroying damaged organelles and proteins, preventing waste accumulation and disease [1] - Researchers from the University of Birmingham and other institutions created human tear gland "organoids" using stem cells and disrupted their autophagy mechanism, resulting in an imbalance in cell composition and a significant reduction in tear protein secretion, mirroring conditions in dry eye patients [1] Group 2: Potential Treatments - The study found that nicotinamide mononucleotide and melatonin can alleviate the dysfunction caused by disrupted autophagy in tear gland organoids, reducing cell death and restoring tear protein secretion [1]
