Ketamine preserves perineuronal nets in chronic stressed mice brain through the inhibition of microglia activation
IBRO Neuroscience Reports July 26, 2026 Jingwen Yang, Ting Huang, Meng Wang et al.
Background Deeper understanding of ketamine’s mechanism of action would contribute to the discovery of novel therapeutic targets with fast-onset actions. To gain insight on the mechanism underlying the antidepressant-like effects of ketamine, we focused on perineuronal nets (PNNs), an extracellular matrix structure that surrounds fast-spiking parvalbumin-positive interneurons and regulates...
