Hypothalamic Perineuronal Nets Are Regulated by Sex and Dietary Interventions

Frontiers in Physiology, 2021
Perineuronal nets (PNNs) are widely present in the hypothalamus, and are thought to provide physical protection and ion buffering for neurons and regulate their synaptic plasticity and intracellular signaling.

The Role of Cerebellar Intrinsic Neuronal Excitability, Synaptic Plasticity, and Perineuronal Nets in Eyeblink Conditioning

Biology
Evidence is strong that, in addition to fine motor control, there is an important role for the cerebellum in cognition and emotion. The deep nuclei of the mammalian cerebellum also contain the highest density of perineural nets—mesh-like structures that ...

Semaphorins in Adult Nervous System Plasticity and Disease

Frontiers in Synaptic Neuroscience, 2021
Semaphorins, originally discovered as guidance cues for developing axons, are involved in many processes that shape the nervous system during development, from neuronal proliferation and migration to neuritogenesis and synapse formation.

11-keto-β-boswellic acid and Z-guggulsterone suppress HMGB1/TLR4 pathway activity and modulate microglial polarization to remodel perineuronal nets after nerve injury

Journal of Advanced Research
Introduction: Remodeling of perineuronal nets is an emerging strategy for treating neuropathic pain (NP) and aligns with the traditional Chinese medicine concept of dispersing blood stasis dispersion and dredging collateral channels.

Running-induced neurogenesis reduces CA1 perineuronal net density without substantial temporal delay

Molecular Brain
Aerobic exercise has many effects on brain function, particularly at the hippocampus. Exercise has been shown to increase the rate of adult neurogenesis within the dentate gyrus and decrease the density of perineuronal nets in area CA1.

Maturation of PNN and ErbB4 Signaling in Area CA2 during Adolescence Underlies the Emergence of PV Interneuron Plasticity and Social Memory

Cell Reports, 2019
Summary: Adolescence is a vulnerable period characterized by major cognitive changes. The mechanisms underlying the emergence of new cognitive functions are poorly understood.

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

Advanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Developmental patterns of extracellular matrix molecules in the embryonic and postnatal mouse hindbrain

Frontiers in Neuroanatomy
Normal brain development requires continuous communication between developing neurons and their environment filled by a complex network referred to as extracellular matrix (ECM). The ECM is divided into distinct families of molecules including hyaluronic

Reconsideration of the Semaphorin-3A Binding Motif Found in Chondroitin Sulfate Using Galnac4s-6st-Knockout Mice

Biomolecules, 2020
The chondroitin sulfate (CS)-rich dense extracellular matrix surrounding neuron cell bodies and proximal dendrites in a mesh-like structure is called a perineuronal net (PNN).
