Rg6, a rare ginsenoside, inhibits systemic inflammation through the induction of interleukin-10 and microRNA-146a.

ABSTRACT: The immunobiological functions of Rg6, a rare ginsenoside from ginseng, have been largely unreported. In this paper, we demonstrate that Rg6 has a significant immunosuppressive function on Toll-like receptor (TLR) 4-induced systemic inflammatory responses. Rg6 was found to negatively regulate pro-inflammatory responses and severity in vivo, and thus induced recovery in mice with lipopolysaccharide (LPS)-induced septic shock and cecal ligation and puncture (CLP)-induced sepsis. Rg6 treatment also facilitated recovery in mice with LPS-induced lung damage via reduced neutrophil infiltration and tumor necrosis factor-α expression in lung tissues. Rg6 injection also downregulated pro-inflammatory cytokines and increased the levels of interleukin (IL)-10 in the serum of septic mice. Mechanistica
