ATP13A2 restrains macrophage NLRP3 inflammasome activation to repress neurodegeneration via modulating mitochondrial homeostasis

2 weeks 1 day ago
Neuro-immune crosstalk is increasingly recognized in Parkinson's disease (PD), and ATP13A2 is well known for its neuroprotective role. However, it remains unclear whether ATP13A2 mutations carried by PD patients contribute to immune dysfunction that exacerbates disease progression. Here, we systematically demonstrate that many ATP13A2 mutations result in a loss-of-expression phenotype. ATP13A2 is highly expressed in macrophages. Myeloid ATP13A2 deficiency causes uncontrolled NLRP3 inflammasome...

Astaxanthin, meclizine, mitoglitazone, pioglitazone, alpha-ketoglutarate, mifepristone, methotrexate, and atorvastatin-telmisartan do not increase lifespan in UM-HET3 mice

2 weeks 1 day ago
The Interventions Testing Program (ITP) evaluated eleven compounds in genetically heterogeneous UM-HET3 mice to assess their potential to extend lifespan. These interventions included both novel agents and previously tested compounds administered at novel doses or starting ages. Despite prior evidence suggesting lifespan benefits of these proposed interventions in other models or under different conditions, none of the tested compounds significantly increased lifespan in male or female mice....
