Perineuronal nets (PNs) are known as chondroitin sulphate-rich, lattice-like coatings of the extracellular matrix. In the cortex of mammalian species investigated so far, they were mainly found around GABAergic neurons, but to a lesser degree also around pyramidal cells. Previous investigations in
As part of the extracellular matrix (ECM), perineuronal nets (PNs) are polyanionic, chondroitin sulfate proteoglycan (CSPG)-rich coatings of certain neurons, known to be affected in various neural diseases. Although these structures are considered as important parts of the neurovascular unit (NVU),
The distribution of perineuronal nets and the potassium channel subunit Kv3.1b was studied in the subdivisions of the cochlear nucleus, the medial nucleus of the trapezoid body, the medial and lateral superior olivary nuclei, the lateral lemniscal nucleus and the inferior colliculus of the rhesus
Perineuronal nets (PNs) of the extracellular matrix have been shown to develop in organotypic slice cultures largely corresponding with regional patterns known from in vivo experiments. In the present study, we use vital labelling to investigate aspects of the cell type-dependent development of PNs
Perineuronal nets (PNs), consisting of extracellular matrix proteoglycans, complexed with hyaluronan and colocalized with tenascins, are associated with distinct neuronal populations in mature mammalian brain. PNs have been shown to appear postnatally during the period of synaptic refinement and
Perineuronal nets (PNs) consisting of polyanionic chondroitin sulfate proteoglycans (CSPG) and other extracellular matrix components create an exceptional microenvironment around certain types of neurons. In rat neocortex, three types of PNs can be distinguished after staining with Wisteria
