Discovery of the day
A new study in APP/PS1 mice reveals that CSF1R inhibition, while reducing microglial proliferation, unexpectedly worsens neuronal network hyperexcitability and epileptiform activity. Researchers found that the CSF1R inhibitor GW2580 exacerbated gamma oscillation disruption and increased network sensitivity to GABAA receptor antagonism, despite partially rescuing synaptic loss. For your work in neurodegenerative disease, this finding is critical: it cautions against indiscriminate microglial suppression in Alzheimer’s disease and highlights the need for therapeutic strategies that preserve microglial homeostatic functions, directly informing the development of safe, targeted immunomodulatory approaches that could be monitored using blood-based proteomic biomarkers of microglial activity.
