title: Food preservatives sodium benzoate and propionic acid and colorant curcumin suppress Th1-type immune response in vitro.
abstract: Food preservatives sodium benzoate and propionic acid and colorant curcumin are demonstrated to suppress in a dose-dependent manner Th1-type immune response in human peripheral blood mononuclear cells (PBMC) in vitro. Results show an anti-inflammatory property of compounds which however could shift the Th1-Th2-type immune balance towards Th2-type immunity.
