Special Issue Information

Dear Colleagues,

Neuronal activity is governed by intricate signaling pathways, ion channel dynamics, and synaptic mechanisms, which together influence processes such as neurotransmission, plasticity, and metabolic regulation. An optimal interplay among distinct cellular and molecular mechanisms not only sustains normal neuronal function and homeostasis but also influences the onset and progression of neurodegenerative diseases and other pathologies of the central nervous system.

Through a comprehensive review of the current literature and original research contributions, this Special Issue aims to explore the cellular and molecular mechanisms regulating neuronal function and homeostasis. We invite research that explores topics such as the regulation of ion channels and receptors, synaptic plasticity, cellular trafficking, neuronal metabolism, and the critical interplay between neurons and glial cells. Studies examining how alterations in these mechanisms contribute to neurodegenerative diseases, as well as those identifying potential biomarkers or therapeutic targets, are of particular interest. Submissions utilizing advanced genomic, proteomic, imaging, or electrophysiological techniques to elucidate these complex pathways are especially welcome.

By bridging the gap between basic science and clinical applications, this Special Issue aims to enhance our understanding of the cellular and molecular mechanisms regulating neuronal function, homeostasis, and neurodegeneration.

The blood–brain barrier (BBB) comprises distinct cell types, including endothelial cells, pericytes, and astrocytes, and is essential for central nervous system (CNS) homeostasis by selectively regulating molecular transport and maintaining integrity. In particular, astrocytes are essential for BBB function, as they maintain BBB integrity through their end-feet, which form a physical and biochemical interface that enhances endothelial cell function and barrier selectivity. Moreover, they secrete growth factors like vascular endothelial growth factor (VEGF) and transforming growth factor-beta (TGF-β), which regulate tight junction (TJ) proteins (e.g., claudins and occludins) crucial for limiting paracellular permeability. Molecular motors like kinesins, dynein, and myosins are essential for these astrocyte functions. By facilitating vesicular trafficking and protein transport, they are essential for various functions, including trafficking of junctional proteins to support BBB integrity, the proper mitochondria localization within astrocyte processes for efficient energy supply, the polarized distribution of aquaporin (AQP)-4 at astrocyte end-feet for regulating water homeostasis across the BBB, and the modulation of neuroinflammatory responses. Moreover, myosin motors modulate actomyosin dynamics to regulate astrocyte process outgrowth, adhesion, migration, and morphology, facilitating their functional roles. Thus, motor protein dysregulation in astrocytes can compromise BBB function and integrity, increasing the risk of neurodegeneration. This review explores the complex interplay between astrocytes and molecular motors in regulating BBB homeostasis, which represents an attractive but poorly explored area of research. Full article
