Chloride (Cl-) channels are crucial in human diseases. Mutations cause loss of function, leading to conditions like cystic fibrosis, while activation contributes to glioma and malaria, suggesting new therapeutic targets.

Area of Science:

  • Molecular Biology
  • Human Physiology
  • Pathogenesis

Background:

  • Chloride (Cl-) channels play vital roles in human health.
  • Genetic studies reveal mutations in Cl- channels cause significant diseases.
  • Abnormal Cl- channel activity is implicated in various pathological conditions.

Purpose of the Study:

  • To review the role of Cl- channels in human disease development.
  • To explore how Cl- channel dysfunction contributes to specific pathologies.
  • To highlight Cl- channels as potential therapeutic targets.

Main Methods:

  • Review of genetic studies linking Cl- channel mutations to diseases.
  • Analysis of recent research on Cl- channel activation in disease progression.
  • Synthesis of evidence on the role of Cl- channels in pathogenesis.

Main Results:

Voltage-gated Ion Channels

Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
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 types of...

Ligand-gated Ion Channels

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
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 include the...

Ion Channels

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
