Chloride channel

A chloride channel is a protein that helps regulate the flow of chloride ions—negatively charged particles—across cell membranes. These channels are vital for maintaining the balance of ions inside and outside cells, which influences processes like nerve signal transmission, muscle function, and fluid balance. When the channel opens, chloride ions move in or out of the cell, helping to control electrical signals and maintain proper cell function. Disruptions in chloride channels can lead to health issues such as cystic fibrosis or neurological problems, highlighting their essential role in bodily processes.
