Immunostimulation by plant polyphenols: a relationship between tumor necrosis factor-alpha production and tannin structure.


The ability of the naturally occurring tumoricidal ellagitannin coriariin A to stimulate secretion of both IL-1beta and TNF-alpha from human peripheral blood mononuclear cells has been demonstrated. Companion studies with the monomeric gallotannin beta-D-pentagalloylglucose and a synthesized dimeric gallotannin-ellagitannin hybrid suggest that TNF-alpha… (More)
