Drug-resilient microglia drive sex-dependent phenotypes in tauopathy mice

In a new paper published today in Nature Communications, the IND’s Condello lab found that tau-mediated neurodegeneration is driven by disease-activated microglia and suppressed by their pharmacological blockade. The authors identified drug dose–dependent and sex-dependent residual microglial phenotypes, neuronal excitotoxicity, and animal survival. Their data argue that therapeutic modulation of microglial activation by CSF1R inhibitors is a potential approach to treating human tauopathies but must consider sex-dependent effects.
