Oenothein B suppresses lipopolysaccharide (LPS)-induced inflammation in the mouse brain. [PDF]

Int J Mol Sci, 2013
Oenothein B has been recently evaluated for its ability to affect inflammatory responses in peripheral tissues. In this study, we examined its effect on the damage to the central nervous system due to systemic inflammation. For this purpose, ICR mice were injected with an intraperitoneal (i.p.) dose of lipopolysaccharide (LPS; 1 mg/kg mouse).

Immunomodulatory activity of oenothein B isolated from Epilobium angustifolium. [PDF]

J Immunol, 2009
Abstract Epilobium angustifolium has been traditionally used to treat of a number of diseases; however, not much is known regarding its effect on innate immune cells. In this study, we report that extracts of E. angustifolium activated functional responses in neutrophils and monocyte/macrophages.

Aging influences the response of T cells to stimulation by the ellagitannin, oenothein B. [PDF]

Int Immunopharmacol, 2015
Several plant extracts, including certain polyphenols, prime innate lymphocytes and enhance responses to secondary stimuli. Oenothein B, a polyphenol isolated from Epilobium angustifolium and other plant sources, enhances IFNγ production by both bovine and human NK cells and T cells, alone and in response to secondary stimulation by cytokines or tumor ...
