Abstract:
Pulmonary hypertension (PH) constitutes a critical challenge in cardiopulmonary medicine with a pathogenesis that is multifaceted and intricate. Ion channels, crucial determinants of cellular electrochemical gradient modulation, have emerged as significant participants in the pathophysiological progression of PH. These channels, abundant on the membranes of pulmonary artery smooth muscle cells (PASMCs) and pulmonary artery endothelial cells (PAECs), pivotally navigate the nuanced interplay of cell proliferation, migration, and endothelial function, each vital to the pulmonary vascular remodeling (PVR) hallmark of PH. Our review delves into the mechanistic insights of potassium, calcium, magnesium, zinc, and chloride ion channels in relation to their involvement in PH. It not only emphasizes the notable advances and discoveries that cast these ion channels as underlying factors in the etiology and exacerbation of PH but also highlights their potential as innovative therapeutic targets.

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...
