Voltage Gated Calcium Channel (Vgcc) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Voltage-Gated Calcium Channel (VGCC) Neurons are neurons expressing L-type, N-type, P/Q-type, R-type, and T-type calcium channels. These channels are essential for calcium influx, neurotransmitter release, and gene expression.
VGCCs in neurons:
- L-type (CaV1.2, 1.3): Dendrites, cell bodies
- N-type (CaV2.2): Presynaptic terminals
- P/Q-type (CaV2.1): Synaptic terminals
- R-type (CaV2.3): Dendrites, terminals
- T-type (CaV3.1-3.3): Thalamus, dendrites
- High-voltage activated (HVA): L, N, P/Q, R
- Low-voltage activated (LVA): T-type
- α1: Pore-forming
- α2δ: Auxiliary subunit
- β: Auxiliary subunit
- γ: Auxiliary subunit
- Neurotransmitter release: Ca²⁺ entry at terminals
- Gene transcription: Nuclear calcium signaling
- Dendritic spikes: Backpropagating action potentials
- Pacemaking: T-type in thalamus
- L-type channel dysregulation
- Aβ affects Ca²⁺ homeostasis
- N-type channels in excitotoxicity
- L-type channels in SNc vulnerability
- Cav1.3 in pacemaking
- Therapeutic targeting
- P/Q-type (CACNA1A) mutations cause epilepsy
- T-type channels in absence seizures
- Antiepileptic drug targets
- CACNA1A mutations cause familial hemiplegic migraine
- P/Q-type channel dysfunction
- VGCC autoantibodies in ALS
- Excitotoxicity mechanisms
The study of Voltage Gated Calcium Channel (Vgcc) Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
