Chemical Synapses

Chemical Synapses

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...

Movement Disorders

Background:

Dystonia is the third most common movement disorder, characterized by involuntary muscle contractions, abnormal postures, and twisting movements.
It is a heterogeneous group of neurological diseases with complex underlying molecular mechanisms.

Approach:

This review focuses on rodent models of specific dystonia gene mutations (DYT-TOR1A, DYT-THAP1, DYT-GNAL, DYT/PARK-GCH1, DYT/PARK-TH, and DYT-SGCE).
It examines the contribution of these models to understanding molecular mechanisms and pathophysiology.

Key Points:

Synaptic alterations in the basal ganglia and cerebellum are a common hallmark across different dystonia forms.
These alterations include abnormal neurotransmitter signaling, receptor trafficking, and synaptic plasticity.

Conclusions:

Rodent models reveal that abnormal motor networks and synaptic dysfunction are critical elements in dystonia pathophysiology.
Findings from these models significantly advance our knowledge of dystonia's molecular underpinnings.
