2-Deoxy-D-glucose impedes T cell-induced apoptosis of keratinocytes in oral lichen planus.

ABSTRACT: Oral lichen planus (OLP) is a T cell-mediated immunoinflammatory disease. Glycolysis plays an essential role in T-cell immune responses. Blocking glycolytic pathway in activated T cells represents a therapeutic strategy for restraint of immunologic process in autoimmune disorders. 2-Deoxy-D-glucose (2-DG) has been widely used to probe into glycolysis in immune cells. This study was aimed to explore the role of glycolysis inhibition by 2-DG on regulating immune responses of OLP-derived T cells. We observed that lactic dehydrogenase A (LDHA) expression was elevated in OLP lesions and local T cells. 2-DG inhibited the expression of LDHA, p-mTOR, Hif1α and PLD2 in T cells; meanwhile, it decreased proliferation and increased apoptosis of T cells. T cells treated by 2-DG showed lower LDHA expres
