Special Issue Information

Dear Colleagues,

We propose to collect research and review articles on the latest progresses in molecular and cellular biology addressing the beneficial impacts of physical exercise in the CNS, both in physiological and pathological conditions. The Special Issue covers the cellular/molecular consequences elicited by physical exercise in the CNS (neurogenesis, angiogenesis, gliogenesis, mitochondrial genesis) that account for cognitive improvements (memory and especially hippocampal-dependent memory, executive functions, processing speed, learning) and therapeutic effects (depression, dementia, Parkinson’s disease, multiple sclerosis, stroke). Exercise also triggers a shift in brain and systemic immune milieu toward anti-inflammatory profiles (microglial phenotype reprogramming) and a regulation of the hypothalamic–pituitary–adrenal axis. The Special Issue addresses how peripheral exerkines / myokines secreted by muscles (cathepsin bêta, irisin) and/or neurotrophins (BDNF, IGF-1, VEGF) trigger the above cited changes. The issue also covers how exercise metabolites (lactate, bêta hydroxybutyrate, ROS) act as signaling molecules that trigger, among other processes, epigenetic modifications (ex: BDNF promotor activation, HDACs inhibition). Finally, the Special Issue could address how physical exercise alters CNS neurotransmission of (1) neuromodulatory systems (biogenic amines, acetylcholine) by modifying their release, turnover, receptor / transporter expression supporting mood, motivation, reward and motor function; (2) GABA/ Glutamate balance, which benefits anxiety regulation, seizures threshold and cortical processing, (3) neuropeptides (endorphins) and endocannabinoids, contributing to mood and nociception regulation.

The influences of physical exercise on CNS functions are thus multiple, and this Special Issue is an occasion to federate articles on this complex topic.

Mitochondrial dysfunction is a key contributor to cognitive impairment, directly affecting neuronal viability, synaptic function, and energy metabolism. In the central nervous system, where energy demand is particularly high, disturbances in mitochondrial dynamics, including impaired oxidative phosphorylation (OxPhos), increased reactive oxygen species (ROS) production, and reduced ATP availability, can compromise synaptic transmission and accelerate cognitive decline. These alterations are commonly observed in neurodegenerative diseases such as Alzheimer’s (AD) and Parkinson’s (PD), in which mitochondrial dysfunction is closely associated with oxidative stress and neuroinflammatory processes. This review aims to investigate the role of mitochondrial dysfunction in cognitive impairment and the effects of physical exercise as a non-pharmacological strategy to mitigate these alterations. Current evidence indicates that exercise promotes mitochondrial biogenesis through activation of the AMPK/PGC-1α pathway, enhances oxidative metabolism, and improves mitochondrial efficiency. Furthermore, exercise reduces oxidative stress and inflammation while stimulating the release of neurotrophic factors, such as brain-derived neurotrophic factor which support neurogenesis, synaptic plasticity, and neuronal survival. Overall, these findings reinforce the importance of mitochondrial integrity in maintaining cognitive function and highlight physical exercise as a promising strategy to counteract mitochondrial dysfunction and delay the progression of neurodegenerative diseases.
