 The study also pinpointed Hcar2 (GPR109A) as a potential agent for butyrate anti-inflammatory impact on microglia. Tests on FRDA mice highlighted the neuroprotective attributes of butyrate intake, bolstering neuromotor performance. In essence, our findings shed light on how cerebellar microglia activation contributes to FRDA and highlight butyrate potential to alleviate neuroinflammation, rectify metabolic imbalances, and boost neuromotor capabilities in FRDA and similar conditions.
