Perineuronal Nets: Plasticity, Protection, and Therapeutic Potential
Trends in Neurosciences, 2019 The relationship between neurons and perineuronal nets (PNNs) is attracting attention as a central mechanism controlling brain plasticity. In the cortex, PNNs primarily surround inhibitory parvalbumin interneurons, playing roles as both a regulator of synaptic plasticity and a protective barrier. PNNs have a delayed developmental trajectory and are key

The Perineuronal ‘Safety’ Net? Perineuronal Net Abnormalities in Neurological Disorders [PDF]
Frontiers in Molecular Neuroscience, 2018 Perineuronal nets (PNN) are extracellular matrix (ECM) assemblies that preferentially ensheath parvalbumin (PV) expressing interneurons. Converging evidence indicates that PV cells and PNN are impaired in a variety of neurological disorders. PNN development and maintenance is necessary for a number of processes within the CNS, including regulation of ...

Perineuronal net degradation in epilepsy [PDF]
Epilepsia, 2015 SummaryObjectiveWe previously reported loss of perineuronal net (PN) immunohistochemical staining around parvalbumin‐positive interneurons in the hippocampus of rats after an episode of status epilepticus (SE). We hypothesized that the loss of thePNcould alter seizure susceptibility and that matrix metalloproteinases (MMPs) were candidates for ...

Perineuronal Net Receptor PTPσ Regulates Retention of Memories [PDF]
Frontiers in Synaptic Neuroscience, 2021 Perineuronal nets (PNNs) have an important physiological role in the retention of learning by restricting cognitive flexibility. Their deposition peaks after developmental periods of intensive learning, usually in late childhood, and they help in long-term preservation of newly acquired skills and information.
