Abstract

Short-Chain Fatty Acids (SCFA) are produced by the intestinal microbiota and have anti-inflammatory and histone deacetylases inhibitors properties. Acute kidney injury (AKI) is characterized by renal inflammation that may impair kidney function. This project evaluated whether treatment with SCFA inflammatory impacts the outcomes of AKI in mice. It was observed that treatment with SCFA protected the AKI. This improvement was associated with less inflammation and lower apoptosis rate. In addition, treatment with acetate decreased the activity of histone deacetylase. Giving bacteria producing acetate, was also observed protection from AKI, along with a lower systemic inflammation. This protection of the AGCC in AKI was also observed in sepsis model. In vitro, SCFA treatment modulated both immune cells and renal cells under hypoxia and inflammatory stimuli. SCFA modulate inflammatory processes in the kidney via epigenetic actions or not, may be a promising tool in the protection of the AKI. (AU)
