Abstract:
Voltage-gated calcium channels (VGCCs) are widely distributed within the central nervous system (CNS) and presumed to play an important role in the pathophysiology of a broad spectrum of CNS disorders including Alzheimer's and Parkinson's disease as well as multiple sclerosis. Several calcium channel blockers have been in clinical practice for many years so that their toxicity and side effects are well studied. However, these drugs are primarily used for the treatment of cardiovascular diseases and most if not all effects on brain functions are secondary to peripheral effects on blood pressure and circulation. While the use of calcium channel antagonists for the treatment of CNS diseases therefore still heavily depends on the development of novel strategies to specifically target different channels and channel subunits, this review is meant to provide an impulse to further emphasize the importance of future research towards this goal.
Insights
Voltage-gated calcium channels (VGCCs) in the central nervous system (CNS) are crucial for brain function and implicated in neurodegenerative diseases. Novel strategies are needed to target brain VGCCs specifically for CNS disorder treatment.
Area of Science:
- Neuroscience
- Pharmacology
Background:
- Voltage-gated calcium channels (VGCCs) are prevalent in the central nervous system (CNS).
- VGCCs are implicated in the pathophysiology of CNS disorders like Alzheimer's, Parkinson's, and multiple sclerosis.
- Existing calcium channel blockers are mainly for cardiovascular diseases, with CNS effects often secondary to peripheral actions.
Purpose of the Study:
- To review the role of VGCCs in CNS disorders.
- To highlight the need for novel strategies targeting CNS-specific VGCCs.
- To emphasize the importance of future research in this area.
Main Methods:
- Literature review of existing research on VGCCs in CNS disorders.
- Analysis of current therapeutic approaches and their limitations.
- Discussion of potential future research directions.
Main Results:
- VGCCs play a significant role in various CNS disorders.
- Current calcium channel blockers have limitations for direct CNS treatment due to systemic side effects.
- Specific targeting of neuronal VGCCs and their subunits is underdeveloped.
Conclusions:
- Targeting VGCCs holds therapeutic potential for CNS diseases.
- Development of novel, brain-specific calcium channel modulators is essential.
- Further research is crucial to advance the use of VGCCs in treating neurological and neurodegenerative conditions.

01:26Voltage-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 types of...
01:19The 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...
01:17Antiepileptic 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...
