Mannose oligosaccharide (MOS) has been shown to promote animal growth, maintain intestinal health, and activate the intestinal immune system. However, the question of whether MOS can stimulate the immune system and alleviate acetylsalicylic acid (ASA)-induced gut damage remains unresolved. The purpose of this study was to investigate the impact of MOS pretreatment on the immunological and anti-inflammatory capabilities of rats with ASA-induced intestinal injury.

Background: Acute lung injury (ALI) significantly impacts the survival rates in intensive care units (ICU). Releasing a lot of pro-inflammatory mediators during the progression of the disease is a core feature of ALI, which may lead to uncontrolled inflammation and further damages the tissues and organs of patients. This study explores the potential therapeutic mechanisms of Dexmedetomidine (Dex) in ALI.

Aims: Carboxylesterase (Ces)1f is implicated in protection against hepatic inflammation, but it is unclear whether the enzyme has an influence in polarization of Kupffer cells (KCs), the innate immune cells mediating hepatic inflammatory injury including acute liver failure (ALF). In the present study, we aim to explore KC polarization induced by Ces1f in mice with lipopolysaccharide/D-galactosamine (LPS/D-GalN)-induced ALF. We adopted a novel delivery system, β-1,3-D-glucan-encapsulated Endoporter-siRNA particles, to specifically target KC Ces1f knockdown via tail vein injection in mice.

This study investigated the preventive and protective effects of Portulaca oleracea polysaccharides (PP) on Acute liver injury (ALI) in mice and its regulatory effects on intestinal microorganisms, and explored the underlying protective mechanisms. Initially, PP was administered, and then CCl4 was used to induce the mouse ALI model. Serum and liver markers were measured by ELISA.
