The 18 kDa translocator protein TSPO localizes on the outer mitochondrial membrane (OMM). Systematically overexpressed at sites of neuroinflammation it is adopted as a biomarker of brain conditions. TSPO inhibits the autophagic removal of mitochondria by limiting PARK2-mediated mitochondrial ubiquitination via a peri-organelle accumulation of reactive(More)
Tuned mitochondrial physiology is fundamental for qualitative cellular function. This is particularly relevant for neurons, whose pathology is frequently associated with mitochondrial deficiencies. Defects in mitochondria are indeed key features in most neurodegenerative diseases such as Alzheimer's Disease (AD), Parkinson's Disease (PD), Huntington's(More)
Mitophagy orchestrates the autophagic degradation of dysfunctional mitochondria preventing their pathological accumulation and contributing to cellular homeostasis. We previously identified a novel chemical tool (hereafter referred to as PMI), which drives mitochondria into autophagy without collapsing their membrane potential (ΔΨm). PMI is an inhibitor of(More)
