Special Issue Information

Dear Colleagues,

Increasing evidence supports the positive impact of exercise on human health. Exercise has been established to reduce the risk for cardiovascular disease and several other chronic diseases, including diabetes mellitus, cancer, obesity, hypertension, bone and joint diseases, and neurodegenerative disease.

Although the exact mechanisms by which this occurs remain unclear, growing research points to exercise’s neuroprotective effects in both human and animal models, with a particular focus on mental health, neurodegenerative conditions, and brain injuries. This Special Issue aims to explore the relationship between exercise and brain function in physiological and/or pathological conditions using clinical and animal studies. Original articles and review articles are welcome.

Abstract
Background: Moderate physical activity (PA) exerts powerful systemic and neuroprotective effects, reducing chronic disease risk and enhancing cognitive and psychological well-being. PA promotes brain plasticity by upregulating neurotrophic factors and stimulating neurogenesis. Given the established role of Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) in [...] Read more.
Background: Moderate physical activity (PA) exerts powerful systemic and neuroprotective effects, reducing chronic disease risk and enhancing cognitive and psychological well-being. PA promotes brain plasticity by upregulating neurotrophic factors and stimulating neurogenesis. Given the established role of Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) in neuronal survival, differentiation, and anti-apoptotic signaling, we aimed to investigate whether moderate PA modulates the endogenous expression of PACAP and its specific receptor PAC1R in the DG and cerebellar cortex. Methods: To this end, twenty-four rats were distributed into sedentary or exercise groups. Immunohistochemical and Western blot analyses were performed to assess PACAP and PAC1R expression. Co-expression with doublecortin (DCX), a marker of immature neurons, was evaluated to explore the direct relationship between PACAP signaling and neurogenesis. Results: Our results showed that moderate PA induced a significant up-regulation of PACAP and PAC1R in both the DG and cerebellar cortex compared to sedentary controls. Moreover, high co-expression of PACAP and DCX was detected in these regions, suggesting an involvement of PACAP in exercise-induced neurogenic processes. Conclusions: These findings demonstrate that moderate physical activity is associated with enhanced PACAP/PAC1R signaling and DCX expression in neurogenic regions, warranting further investigation into its specific contribution to exercise-induced brain plasticity.

The cerebellum plays a key role in regulating movement, coordination, and certain cognitive functions. Purkinje cells are the principal neurons of the cerebellum, essential for integrating information and modulating output to other parts of the central nervous system. Physical exercise is crucial for maintaining psychophysical well-being and improving quality of life. Moreover, its beneficial effects on brain health are well established. After a brief overview of cerebellar anatomy, this narrative review aims to summarize current experimental evidence on the effects of physical activity on Purkinje cells, particularly in the context of neuronal plasticity and neuroprotection. Special attention is given to structural and functional adaptations under both physiological and pathological conditions, including neurodegenerative diseases, neurodevelopmental disorders, traumatic brain injury, and aging. Overall, the available findings suggest that Purkinje cells represent a key cellular target of exercise-induced cerebellar plasticity. Physical activity may therefore contribute to preserving cerebellar function and promoting neuroprotection through mechanisms involving structural remodeling and synaptic adaptation of Purkinje cells.
