We developed chemical-inducible GPCRs based on DREADD allowing CNO-mediated stimulation and recapitulated entire signaling of β2-adrenergic receptor including also the inflammatory and migratory response in microglia.

We optimized adeno-associated viruses (AAVs) transduction efficiency and specificity for retinal microglia in vivo and found that certain disease environments influence microglial susceptibility to viral transduction

We found that repeated anesthetic dosage of ketamine induces microglia-dependent PNN removal, which reinstates juvenile-like plasticity. We also recapitulated the ketamine-mediated effects with selective 60-Hz light entrainment paradigm.
