Component-specific reduction in perineuronal nets in senescence-accelerated mouse strains
IBRO Neuroscience Reports, 2023 With increased life expectancy, age-related diseases are a significant health concern in Western societies. Animal models (e.g., rodents) have been used to understand age-related changes in brain function—particularly through the senescence-accelerated ...

Perineuronal nets affect memory and learning after synapse withdrawal
Translational Psychiatry, 2022 Perineuronal nets (PNNs) enwrap mature neurons, playing a role in the control of plasticity and synapse dynamics. PNNs have been shown to have effects on memory formation, retention and extinction in a variety of animal models.

Expression of aggrecan components in perineuronal nets in the mouse cerebral cortex
IBRO Reports, 2018 Specific regions of the cerebral cortex are highly plastic in an organism’s lifetime. It is thought that perineuronal nets (PNNs) regulate plasticity, but labeling for Wisteria floribunda agglutinin (WFA), which is widely used to detect PNNs, is observed

Regulation of the E/I-balance by the neural matrisome
Frontiers in Molecular Neuroscience, 2023 In the mammalian cortex a proper excitatory/inhibitory (E/I) balance is fundamental for cognitive functions. Especially γ-aminobutyric acid (GABA)-releasing interneurons regulate the activity of excitatory projection neurons which form the second main ...

Cocaine-induced plasticity in the cerebellum of sensitised mice [PDF]
, 2015 Rationale Prior research has accumulated a substantial amount of evidence on the ability of cocaine to produce short- and long-lasting molecular and structural plasticity in the corticostriatal-limbic circuitry. However, traditionally, the cerebellum

Cortical fast-spiking parvalbumin interneurons enwrapped in the perineuronal net express the metallopeptidases Adamts8, Adamts15 and Neprilysin. [PDF]
, 2014 The in situ hybridization Allen Mouse Brain Atlas was mined for proteases expressed in the somatosensory cerebral cortex. Among the 480 genes coding for protease/peptidases, only four were found enriched in cortical interneurons: Reln coding for reelin ...

Nature Communications, 2018 Brain tumours are associated with epilepsy. Here the authors show, using a mouse model, that the degradation of perineuronal nets around fast spiking interneurons near the tumour contribute to seizures by increasing their membrane capacitance and firing.

Reduction in parvalbumin expression not loss of the parvalbumin-expressing GABA interneuron subpopulation in genetic parvalbumin and shank mouse models of autism [PDF]
, 2016 Background A reduction of the number of parvalbumin (PV)-immunoreactive (PV⁺) GABAergic interneurons or a decrease in PV immunoreactivity was reported in several mouse models of autism spectrum disorders (ASD). This includes Shank mutant mice, with SHANK

Chondroitin sulfates and their binding molecules in the central nervous system [PDF]
, 2017 Chondroitin sulfate (CS) is the most abundant glycosaminoglycan (GAG) in the central nervous system (CNS) matrix. Its sulfation and epimerization patterns give rise to different forms of CS, which enables it to interact specifically and with a ...
