Summary
Actin
Area of Science:
- Neuroscience
- Cell Biology
Background:
- The actin cytoskeleton plays a dual role in synapses, acting as both structural support and a dynamic regulator.
- Its involvement extends beyond morphology to actively modulating synaptic efficacy.
Purpose of the Study:
- To review recent advancements in understanding the actin cytoskeleton's role in synaptic function.
- To highlight how actin influences synaptic plasticity and strength.
Main Methods:
- This review synthesizes findings from various studies on actin dynamics and signaling pathways at synapses.
- It integrates research on morphological changes and synaptic efficacy modulation.
Main Results:
- Actin's dynamic nature allows it to regulate synaptic efficacy at both pre- and postsynaptic terminals.
- Distinct actin pools and signaling pathways enable uncoupling of morphological plasticity from synaptic strength changes.
Conclusions:
- The actin cytoskeleton is a critical and multifaceted regulator of synaptic function.
- Further research into actin-dependent mechanisms can reveal novel therapeutic targets for neurological disorders.

01:26Chemical 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...

01:26Introduction to Actin
Actin is a highly conserved cytoskeletal protein found abundantly in eukaryotic cells. It constitutes 10% weight of the total cellular protein in muscle cells, while in non-muscle cells, it is lower and makes up around 1–5 percent of the total cell protein. Actin found in the unicellular amoebae and complex multicellular animals is around 80% similar, demonstrating their conservation over a billion years of evolution. Actin coding genes are conserved within species and across different species.
01:19Actin Filament Depolymerization
Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).

01:29Relaxation of Skeletal Muscles
The period of muscle contraction primarily influences the duration of stimulation at the neuromuscular junction (NMJ), the presence of free calcium ions in the sarcoplasm, and the availability of energy or ATP to support contractions.
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.

01:11Formation of Higher-order Actin Filaments
The polymerization of G-actin monomers into filamentous F-actin is a multi-step process. Once the F-actins are formed, they can bundle together in different arrangements to form higher-order networks and regulate cellular functions. Common examples include the formation of lamellipodia and filopodia at the cell's leading edge by actin reorganization in a migrating cell. The microvilli on the brush border epithelial cells are also formed through the F-actin network.
