Glycolysis inhibition functionally reprograms T follicular helper cells and reverses lupus.

ABSTRACT: Systemic lupus erythematosus (SLE) is an autoimmune disease in which the production of pathogenic autoantibodies depends on T follicular helper (T_FH) cells. This study investigated the mechanisms by which the glycolysis inhibitor 2-deoxy-d-glucose (2DG) reduces the expansion of T_FH cells and the associated production of autoantibodies in lupus-prone mice. Integrated cellular, transcriptomic, epigenetic, and metabolic analyses showed that 2DG reversed the enhanced cell expansion and effector functions, as well as mitochondrial and lysosomal defects in lupus T_FH cells, including increased expression of chaperone-mediated autophagy (CMA) markers associated with Toll-like receptor 7 activation. Importantly, adoptive transfer of 2DG-reprogrammed T_FH c
