Oligodendrocyte Precursor Cells in Demyelination Repair: Mechanisms, Crosstalk, and Therapeutic Frontiers

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT In multiple sclerosis (MS), demyelination is often accompanied by severe motor and cognitive disability. Remyelination is the process of regenerating new myelin sheath on impaired axons, which is typically carried out by oligodendrocyte precursor cells (OPCs).

Metabolism peritumorous zone and alteration AMPAand NMDA-glutamate receptors in the pathogenesis of gliomas of the cerebral hemispheres

open access: yesУчёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2014
Examined 12 patients with gliomas of the big hemispheres of a brain. Used immunoenzyme method for semiquantitative determination of the level of autoantibodies to NR2A-subunit of NMDA- and GluR1-subunit of AMPA-receptors of glutamate.

Intratumoral Nerve Phased Development: A Promising Therapeutic Target

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT The nervous system has emerged as a critical regulator of tumor biology, engaging in dynamic crosstalk with cancer cells. Although the protumorigenic role of innervation is well established, increasing attention is now directed toward reciprocal influences—how tumors actively shape and remodel local nerve networks within the tumor ...

Ligand-dependent opening of the multiple AMPA receptor conductance states: a concerted model.

open access: yesPLoS ONE, 2015
Modulation of the properties of AMPA receptors at the post-synaptic membrane is one of the main suggested mechanisms underlying fast synaptic transmission in the central nervous system of vertebrates.

Pregnenolone Reduces L‐Dopa‐Induced Dyskinesias in Female Parkinsonian Monkeys

open access: yesMovement Disorders, EarlyView.
Pregnenolone is the first neurosteroid synthesized from cholesterol in the brain. Ovariectomized female monkeys were tested as a model of women in menopause. They were lesioned with MPTP modeling Parkinson's disease and treated with levodopa (L‐dopa) to induce dyskinesias.

A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

open access: yesNeuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.

Mechanism of Ammonia‐Induced Brain Damage in Chinese Striped‐Necked Turtle (Mauremys sinensis)

open access: yesIntegrative Zoology, EarlyView.
High levels of ammonia disrupt the integrity of the brain barrier in Mauremys sinensis, leading to tissue edema. This, in turn, triggers a series of cascade reactions, including disturbances in neurotransmitter levels, particularly glutamate, which might further exacerbate the neurotoxic effects.

Аlterationdegree of NMDA and AMPA receptors of glutamate in the pathogenesis of the disease and technological peculiarities of surgical treatment of the hemispheric glioma-swith the epileptic syndrome

open access: yesУчёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2014
The development of effective approaches to the treatment of patients with symptomatic tumor epilepsy was determined by the level of our fundamental knowledge of the basic mechanisms of epileptogenesis on cellular and molecular level.
