Chondroitin sulfate glycan sulfation patterns influence histochemical labeling of perineuronal nets: a comparative study of interregional distribution in human and mouse brain

Glycobiology
Perineuronal nets (PNNs) are a condensed subtype of extracellular matrix that form a net-like coverings around certain neurons in the brain. PNNs are primarily composed of chondroitin sulfate (CS) proteoglycans from the lectican family that consist of CS-

Extracellular baskets in inner hair cells and perineuronal nets in auditory nerves: Changes in noise-induced hearing loss rats.

Neuroscience Letters
BACKGROUND The extracellular baskets of cochlear inner hair cell (IhC) ribbon synapses have been suggested to regulate synaptic coupling. This study aimed to investigate the expression of components of the extracellular baskets of the IhCs, chondroitin ...

Perineuronal Nets: From Structure to Neurological Disorders

Current Medicinal Chemistry
Perineuronal nets (PNN) is condensed extracellular matrix (ECM) in the central nervous system (CNS), which surrounds cell soma, axon initial segments, and synapses. In the brain, most neurons surrounded by PNN are interneurons, especially the parvalbumin-expressing interneurons (PVI).

Perineuronal Nets in the Superior Olivary Complex

2018
Abstract This chapter addresses perineuronal nets in the superior olivary complex, a collection of nuclei in the auditory brainstem that are involved in the processing of sound source location. Perineuronal nets, a specific form of extracellular matrix, are believed to control synaptic plasticity.

Microglia inversely regulate the level of perineuronal nets with the treatment of lipopolysaccharide and valproic acid.

Neuroscience Letters
Perineuronal nets (PNNs) are extracellular matrix which mostly surround the inhibitory neurons. They are changed in several brain diseases, such as autism spectrum disorder, but the mechanism of PNNs degradation is still unclear.

2.26 - Perineuronal nets in memory

Perineuronal nets (PNN) are specialized structures surrounding certain nerve cells. Although considered as a part of the extracellular matrix (ECM), they are composed of sugars stemming from the cells they surround as well as of extracellular glycoproteins.
