The extracellular matrix and perineuronal nets in memory

open access: yesMolecular Psychiatry, 2022
AbstractAll components of the CNS are surrounded by a diffuse extracellular matrix (ECM) containing chondroitin sulphate proteoglycans (CSPGs), heparan sulphate proteoglycans (HSPGs), hyaluronan, various glycoproteins including tenascins and thrombospondin, and many other molecules that are secreted into the ECM and bind to ECM components. In addition,

Beta3Gn-T7 Is a Keratan Sulfate β1,3 N-Acetylglucosaminyltransferase in the Adult Brain

open access: yesFrontiers in Neuroanatomy, 2022
Keratan sulfate (KS) glycan is covalently attached to a core protein of proteoglycans. KS is abundant in neuropils and presents densely in close proximity to the perineuronal region of the perineuronal net-positive neurons in the adult brain under ...

Parvalbumin interneuron alterations in stress-related mood disorders: A systematic review

open access: yesNeurobiology of Stress, 2021
Stress-related psychiatric disorders including depression involve complex cellular and molecular changes in the brain, and GABAergic signaling dysfunction is increasingly implicated in the etiology of mood disorders.

Experience-dependent plasticity and modulation of growth regulatory molecules at central synapses. [PDF]

open access: yesPLoS ONE, 2011
Structural remodeling or repair of neural circuits depends on the balance between intrinsic neuronal properties and regulatory cues present in the surrounding microenvironment.

Perineuronal Nets and Their Role in Synaptic Homeostasis [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Extracellular matrix (ECM) molecules that are released by neurons and glial cells form perineuronal nets (PNNs) and modulate many neuronal and glial functions. PNNs, whose structure is still not known in detail, surround cell bodies and dendrites, which leaves free space for synapses to come into contact.

Neurogenesis mediated plasticity is associated with reduced neuronal activity in CA1 during context fear memory retrieval

open access: yesScientific Reports, 2022
Postnatal hippocampal neurogenesis has been demonstrated to affect learning and memory in numerous ways. Several studies have now demonstrated that increased neurogenesis can induce forgetting of memories acquired prior to the manipulation of ...

Environmental Enrichment From Birth Impacts Parvalbumin Expressing Cells and Wisteria Floribunda Agglutinin Labelled Peri-Neuronal Nets Within the Developing Murine Striatum

open access: yesFrontiers in Neuroanatomy, 2019
Environmental enrichment can dramatically affect both the development and function of neural circuits. This is accomplished, at least in part, by the regulation of inhibitory cellular networks and related extracellular matrix glycoprotein structures ...

Perineuronal Nets and Metal Cation Concentrations in the Microenvironments of Fast-Spiking, Parvalbumin-Expressing GABAergic Interneurons: Relevance to Neurodevelopment and Neurodevelopmental Disorders

open access: yesBiomolecules, 2021
Because of their abilities to catalyze generation of toxic free radical species, free concentrations of the redox reactive metals iron and copper are highly regulated.

Proteoglycan Sulphation in the Function of the Mature Central Nervous System

open access: yesFrontiers in Integrative Neuroscience, 2022
Chondroitin sulphate and heparan sulphate proteoglycans (CSPGS and HSPGs) are found throughout the central nervous system (CNS). CSPGs are ubiquitous in the diffuse extracellular matrix (ECM) between cells and are a major component of perineuronal nets ...

Perineuronal nets: Cruise from a honeycomb to the safety nets

open access: yesBrain Research Bulletin, 2022
The extracellular matrix (ECM) is a significant component of the brain, constituting up to 20 % of the brain volume and perform multifarious functions during development, maturation and regeneration of the central nervous system (CNS). ECM molecules assemble systematically to form a relatively rigid and unique lattice-like structure, known as ...
