Cell membrane stress upon viral infection induces expression and stabilization of host SMPDL3B, which, in turn, degrades cGAMP to suppress cGAS-STING signaling and promote viral replication @cp-immunity.bsky.social

I am thrilled to announce that I will be starting my lab at
@washumedicine.bsky.social, Department of Pathology & Immunology as an Assistant Professor this month. The lab will study the role of innate immunity in neurodegeneration and brain aging. We'll be hiring at all levels. Details soon!

The R136S mutation in the APOE3 gene confers resilience against tau pathology via inhibition of the cGAS-STING-IFN pathway The Christchurch mutation (R136S) in the APOE3 (E3S/S) gene is associated with attenuated tau load and cognitive decline despite the presence of a cau…

🚨Our new paper is out!🚨 We uncover a protective mechanism of the rare APOE3 Christchurch (R136S) mutation against tauopathyβ€”by suppressing microglial cGAS–STING–interferon (IFN) pathway, a key inflammatory axis triggered by tau. www.sciencedirect.com/science/arti...

Naguib et al. show that R136S suppresses microglial cGAS-STING-IFN signaling in tauopathy mice. Inhibiting cGAS preserves synapses and mimics R136S-linked gene expression, suggesting that cGAS suppression is a key part of the underlying protective effects of R136S.
