Cl- channels

Chloride (Cl⁻) channels are specialized protein structures in cell membranes that allow chloride ions to pass into or out of the cell. They help regulate cell volume, maintain electrical balance, and control processes like nerve signaling and muscle function. When these channels open, chloride ions move according to their concentration and electrical gradients, which can stabilize the cell's charge or contribute to signaling. Proper function of Cl⁻ channels is essential for overall cellular health, and their dysfunction can be linked to diseases such as cystic fibrosis and certain neurological disorders.
