Daeshiho-tang attenuates inflammatory response and oxidative stress in LPS-stimulated macrophages by regulating TLR4/MyD88, NF-κB, MAPK, and Nrf2/HO-1 pathways.

ABSTRACT: Daeshiho-tang (DSHT), a traditional herbal formula with diverse pharmacological effects, has shown promise in medicine owing to its anti-hypertensive, anti-diabetic, and anti-inflammatory properties. However, the precise molecular mechanism underlying these effects remains unclear. Thus, we investigated the effect of DSHT on inflammatory response and oxidative stress to understand its molecular mechanism using lipopolysaccharide (LPS)-induced macrophage (RAW 264.7) cells. DSHT decreased the contents of nitric oxide (NO) and prostaglandin E₂ (PGE₂) through downregulating inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expressions. DSHT suppressed the LPS-induced TLR4 as well as MyD88, subsequently suppressing the NF-κB activation and the pho
