Perineuronal nets in brain physiology and disease

open access: yesSeminars in Cell & Developmental Biology, 2019
Perineuronal nets (PNNs) in the brain are condensed glycosaminoglycan-rich extracellular matrix structures with heterogeneous composition yet specific organization. They typically assemble around a subset of fast-spiking interneurons that are implicated in learning and memory.

Cortical Layer‐Specific Remodelling of Parvalbumin and Perineuronal Net Networks in Alcohol Use Disorder

open access: yesNeuropathology and Applied Neurobiology, Volume 52, Issue 1, February 2026.
Remodelling of perineuronal nets on cortical parvalbumin neurons in layers IV–VI occurs in human alcohol use disorder, suggests reduced plasticity in cortical output circuits driving habitual behaviour. ABSTRACT Background Alcohol use disorder (AUD) is a chronically relapsing condition marked by a pathological shift in behaviour, where excessive ...

Early Destruction of the Extracellular Matrix around Parvalbumin-Immunoreactive Interneurons in Creutzfeldt-Jakob Disease

open access: yesNeurobiology of Disease, 1999
GABA-interneurons immunoreactive (IR) for the calcium-binding protein parvalbumin are lost during the early stages of Creutzfeldt-Jakob disease (CJD) and diminution in their number may partially account for the neurological disturbances manifested in ...

Neuroanatomical Alterations in the CNTNAP2 Mouse Model of Autism Spectrum Disorder

open access: yesBrain Sciences, 2023
Autism spectrum disorder (ASD) is associated with neurodevelopmental alterations, including atypical forebrain cellular organization. Mutations in several ASD-related genes often result in cerebral cortical anomalies, such as the abnormal developmental ...

Exploring the Production of Extracellular Matrix by Astrocytes in Response to Mimetic Traumatic Brain Injury [PDF]

open access: yes, 2016
Following injury to the central nervous system, extracellular modulations are apparent at the site of injury, often resulting in a glial scar. Astrocytes are mechanosensitive cells, which can create a neuroinhibitory extracellular environment in response

Blocking human fear memory with the matrix metalloproteinase inhibitor doxycycline [PDF]

open access: yes, 2017
Learning to predict threat is a fundamental ability of many biological organisms, and a laboratory model for anxiety disorders. Interfering with such memories in humans would be of high clinical relevance.

Inhibitory circuit dysfunction as a potential contributor to cortical reorganization in Glioblastoma progression

open access: yesNeurobiology of Disease
Glioblastoma (GBM) is a highly aggressive brain tumor that infiltrates surrounding brain tissue, profoundly affecting adjacent cortical areas. This study investigates how GBM reshapes the peritumoral cortex by examining plasticity changes in two GBM ...

Toxoplasma gondii infection damages the perineuronal nets in a murine model [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz
BACKGROUND Behavioral and neurochemical alterations associated with toxoplasmosis may be influenced by the persistence of tissue cysts and activation of an immune response in the brain of Toxoplasma gondii-infected hosts.

Tackling obstacles for gene therapy targeting neurons: disrupting perineural nets with hyaluronidase improves transduction. [PDF]

open access: yes, 2013
Gene therapy has been proposed for many diseases in the nervous system. In most cases for successful treatment, therapeutic vectors must be able to transduce mature neurons. However, both in vivo, and in vitro, where preliminary characterisation of viral

Anti‐Neuroinflammation Activity of Essential Oils and Fatty Acids

open access: yesFood Science &Nutrition, Volume 14, Issue 1, January 2026.
Neuroinflammation plays a pivotal role in the pathogenesis of neurodegenerative disorders, including Alzheimer's disease (AD) and Parkinson's disease (PD). Current pharmacological interventions, such as NSAIDs and corticosteroids, are limited by systemic toxicity and insufficient efficacy in targeting chronic neuroinflammatory processes.
