Abstract:
Calcium influx via L-type (Cav1.2 and Cav1.3) calcium channels is tightly regulated to ensure optimal intracellular calcium levels. Although much is known about acute modulation of these channels by second messengers, the mechanisms that control their trafficking to and from the plasma membrane remain poorly understood. In this issue of Neuron, Green and colleagues demonstrate that the opening of L-type calcium channels results in negative feedback regulation due to their calcium-dependent internalization.

Feedback Regulation of Calcium Concentration
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
