Perineuronal nets and schizophrenia: The importance of neuronal coatings [PDF]
Neuroscience and Biobehavioral Reviews, 2014 Schizophrenia is a complex brain disorder associated with deficits in synaptic connectivity. The insidious onset of this illness during late adolescence and early adulthood has been reported to be dependent on several key processes of brain development including synaptic refinement, myelination and the physiological maturation of inhibitory neural ...

The two faces of perineuronal nets
NeuroReport, 2000Perineuronal nets are extracellular structures enwrapping the soma and proximal dendrites of some neurons known to be parvalbumin immunoreactive. The composition of the nets is not completely known, but it can change between different neurons. We studied the heterogeneous composition of a specific component of perineuronal nets, the signaling molecule ...

The perineuronal net and the control of CNS plasticity
Cell and Tissue Research, 2012Perineuronal nets (PNNs) are reticular structures that surround the cell body of many neurones, and extend along their dendrites. They are considered to be a specialized extracellular matrix in the central nervous system (CNS). PNN formation is first detected relatively late in development, as the mature synaptic circuitry of the CNS is established and

Characterization of Perineuronal Nets in the Human Cerebellum
The CerebellumPerineuronal nets (PNNs) are condensed extracellular matrix structures that regulate synaptic plasticity and neuronal stability. While their distribution and function have been well characterized in rodents, PNNs remain largely understudied in the human cerebellum.

Perineuronal nets could be visualized with some Golgi methods in the rat's brain. Nets were seen in telencephalic, diencephalic and mesencephalic structures covering somata and proximal dendrites of different neuronal types. Some nets could be found originating from microglia cells. In most cases their origin is not recognizable.

Perineuronal net expression in the brain of a hibernating mammal
Brain Structure and Function, 2019During hibernation, mammals like the 13-lined ground squirrel cycle between physiological extremes. Most of the hibernation season is spent in bouts of torpor, where body temperature, heart rate, and cerebral blood flow are all very low. However, the ground squirrels periodically enter into interbout arousals (IBAs), where physiological parameters ...

Extracellular matrix and perineuronal nets in CNS repair
Developmental Neurobiology, 2011AbstractA perineuronal net (PNN) is a layer of lattice‐like matrix which enwraps the surface of the soma and dendrites, and in some cases the axon initial segments, in sub‐populations of neurons in the central nervous system (CNS). First reported by Camillo Golgimore than a century ago, the molecular structure and the potential role of this matrix have

Perineuronal Nets: From Structure to Neurological Disorders
Current Medicinal ChemistryPerineuronal 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
2018Abstract 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.
