研究目的: |
小胶质细胞活化是帕金森病(PD)的核心病理标志。在促炎激活后,小胶质细胞将代谢从氧化磷酸化(OXPHOS)转向糖酵解。糖酵解驱动的乳酸积累有助于PD的发展和进展。然而,其潜在机制尚不清楚。这项工作共同证明了乳酸/Dld-K127/丙酮酸正反馈回路在“代谢-表观遗传”水平上驱动DA神经元损伤,并表明抑制这种恶性循环是治疗PD的有前景的治疗靶点。 |

Objectives of Study: |
Microglial activation is a central pathological hallmark of Parkinson's disease (PD). Microglia switch metabolism from oxidative phosphorylation (OXPHOS) toward glycolysis upon pro-in?ammatory activation. Glycolysis-drived lactylate accumulation contributed to the development and progression of PD. However, the underlying mechanisms remain unclear. This work demonstrated a lactate/Dld-K127/pyruvate positive feedback loop that drived DA neuronal damage in "metabolism - epigenetic" level and suggested that suppressing this vicious feedback circle as a promising therapeutic target for PD |
