Ion Channel Signaling and Calcium Dynamics in Cell Physiology and Disease
This community investigates how cells control the flow of ions—primarily calcium, potassium, and sodium—through membrane channels to regulate essential functions like contraction, signaling, and survival. The work focuses on the molecular mechanisms of these channels and their role in both healthy physiology and disease states such as epilepsy, cancer, and neurodegeneration.
The research centers on voltage-gated and ligand-gated ion channels, with a heavy emphasis on calcium homeostasis and mitochondrial calcium uptake. Recurring themes include the structural and functional characterization of potassium and sodium channels, the dynamics of intracellular calcium signaling, and the role of transient receptor potential (TRP) channels in sensory perception and pain. Applications span cardiac electrophysiology, neuronal excitability, and smooth muscle contraction. The community also explores how dysregulation of these channels contributes to conditions like Alzheimer’s disease, breast cancer, and neuropathic pain, often using mouse models and advanced calcium imaging techniques to observe these processes in real-time.
The largest share of the community's output is found in calcium research, accounting for 8.0% of all calcium-related papers, followed by potassium at 7.9% and sodium at 2.5%. Calcium also contributes the highest absolute number of papers within this group, with 25,750 entries.
The community comprises 76,580 papers, publishing most frequently in Cell Calcium, the Journal of Neuroscience, and the Journal of Biological Chemistry.
Recent work continues to focus on the therapeutic potential of ion channel modulators, including studies on Piezo1 mechanosensitive channels in bone health and KCNQ2 channel dysfunction in amyotrophic lateral sclerosis. Newer papers also examine calcium-dependent mitophagy in aging and the role of blood-brain barrier disruption in epilepsy, reflecting ongoing efforts to link channel biology to clinical outcomes.
