TGFB1 and pemphigus foliaceus: A recent study indicated that 50 mg/kg BA (i.p. administration) effectively suppresses bleomycin (BLM)-induced PF in rats by decreasing the expression of hydroxyproline, TGF-β, collagen I, collagen III, and TNF-α, enhancing the function of anti-oxidative stress, and inhibiting apoptotic protein expression.
