Summary
Liquid-liquid phase separation forms cell condensates, crucial for nervous system synapse assembly and function. Disruptions in this process are linked to neurological diseases, suggesting phase separation as a therapeutic target.
Area of Science:
- Cell biology
- Neuroscience
- Biochemistry
Background:
- Liquid-liquid phase separation (LLPS) regulates cellular activity through membrane-less condensate formation.
- LLPS is vital for synaptic assembly and function in the nervous system.
- Aberrant phase separation is implicated in various diseases, including cancer and neurological disorders.
Purpose of the Study:
- To review the role of phase separation in synapse assembly and plasticity.
- To discuss the involvement of abnormal phase separation in neurological diseases.
- To explore potential therapeutic strategies targeting phase separation for neurological conditions.
Main Methods:
- Literature review of studies on phase separation in cellular biology and neuroscience.
- Analysis of research linking phase separation to synaptic function and neurological diseases.
- Synthesis of information on therapeutic interventions targeting phase separation.
Main Results:
- Phase separation is essential for the dynamic assembly and plasticity of 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...
