This 2020 study investigated taurine's antiallergic effects on allergic rhinitis (AR) through both in vitro and in vivo models. In AR patients, serum levels of extracellular superoxide dismutase (SOD3) were reduced. Taurine treatment increased SOD3 expression in human mast cells via activation of peroxisome proliferator-activated receptor-γ (PPAR-γ), leading to decreased
