Fig. 5From: Tacrolimus reverses pemphigus vulgaris serum-induced depletion of desmoglein in HaCaT cells via inhibition of heat shock protein 27 phosphorylationPictorial presentation of the proposed hypothesis pertaining to apoptosis in the pathogenesis of pemphigus vulgaris. PV-IgG depletes desmoglein (Dsg)3 and causes actin filament reorganization, leading to acantholysis. FK506 blocks heat shock protein (HSP) 27 phosphorylation and prevents changes in Dsg3 depletion and actin filament reorganizationBack to article page
