Benign Lymphoepithelial Lesion of Lacrimal Gland:Macrophage

发布时间：2021-10-28 22:31

　　Despite the decades that have elapsed since the discovery of benign lymphoepithelial lesion（BLEL）the exact etiology,and mechanisms of its pathogenesis are still elusive.There is,however,a consensus that BLEL is an inflammatory disease,but the mediators of this inflammatory response and their role in the pathogenesis of the disease are unknown.The main objective of this thesis was,therefore,to provide a fundamental understanding of the cellular and molecular processes that regulate the pathogenes...
