Neurons ensheathed by perineuronal nets are prone to hyperphosphorylation of tau protein in the hibernating Syrian hamster brain [PDF]

Scientific Reports
Perineuronal nets (PNNs) are a specialized form of neuronal extracellular matrix that often ensheath highly active cells, such as parvalbumin-positive (PV+) interneurons.

Shock-Induced Damage Mechanism of Perineuronal Nets

Biomolecules, 2021
The perineuronal net (PNN) region of the brain’s extracellular matrix (ECM) surrounds the neural networks within the brain tissue. The PNN is a protective net-like structure regulating neuronal activity such as neurotransmission, charge balance, and ...

Layer-specific expression of extracellular matrix molecules in the mouse somatosensory and piriform cortices [PDF]

IBRO Reports, 2019
In the developing central nervous system (CNS), extracellular matrix (ECM) molecules have regulating roles such as in brain development, neural-circuit maturation, and synaptic-function control.

Sustained diabetes remission induced by FGF1 involves a shift in transcriptionally distinct AgRP neuron subpopulations [PDF]

Molecular Metabolism
In rodent models of type 2 diabetes, a single intracerebroventricular (icv) injection of fibroblast growth factor 1 (FGF1) induces sustained remission of hyperglycemia. Overactive agouti-related peptide (AgRP) neurons, located in the hypothalamic arcuate

Sex differences in structural and receptor mRNA expression in the ventral anterior cingulate cortex and a potential role of perineuronal nets in monogamous pair bond establishment (Peromyscus californicus) [PDF]

Biology of Sex Differences
The monogamous California mouse (Peromyscus californicus) exhibits distinct behavioral changes during pair bond formation. Using a detailed temporal behavioral analysis over seven days, we found a rapid decrease in aggression within 24 h of pair ...

Altered inhibitory function in hippocampal CA2 contributes in social memory deficits in Alzheimer’s mouse model

iScience, 2022
Summary: Parvalbumin (PV)-expressing interneurons which are often associated with the specific extracellular matrix perineuronal net (PNN) play a critical role in the alteration of brain activity and memory performance in Alzheimer’s disease (AD).

Sensory Experience as a Regulator of Structural Plasticity in the Developing Whisker-to-Barrel System

Frontiers in Cellular Neuroscience, 2021
Cellular structures provide the physical foundation for the functionality of the nervous system, and their developmental trajectory can be influenced by the characteristics of the external environment that an organism interacts with.

Brevican, Neurocan, Tenascin-C, and Tenascin-R Act as Important Regulators of the Interplay Between Perineuronal Nets, Synaptic Integrity, Inhibitory Interneurons, and Otx2

Frontiers in Cell and Developmental Biology, 2022
Fast-spiking parvalbumin interneurons are critical for the function of mature cortical inhibitory circuits. Most of these neurons are enwrapped by a specialized extracellular matrix (ECM) structure called perineuronal net (PNN), which can regulate their ...

Brain ageing changes proteoglycan sulfation, rendering perineuronal nets more inhibitory [PDF]

, 2017
Chondroitin sulfate (CS) proteoglycans in perineuronal nets (PNNs) from the central nervous system (CNS) are involved in the control of plasticity and memory.

Impact of Perineuronal Net Removal in the Rat Medial Prefrontal Cortex on Parvalbumin Interneurons After Reinstatement of Cocaine Conditioned Place Preference

Frontiers in Cellular Neuroscience, 2022
Parvalbumin (PV)-positive cells are GABAergic fast-spiking interneurons that modulate the activity of pyramidal neurons in the medial prefrontal cortex (mPFC) and their output to brain areas associated with learning and memory.
