Summary
Protein synthesis and degradation are crucial for synaptic plasticity. This review highlights how maintaining protein homeostasis regulates synaptic function and long-term memory formation.
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- De novo protein synthesis is vital for synaptic transmission and plasticity.
- mRNA translation in the hippocampus is spatially controlled.
- Dendritic protein synthesis is essential for long-term synaptic plasticity.
Purpose of the Study:
- To review experimental data on protein homeostasis in synaptic plasticity.
- To highlight the role of protein degradation in synaptic plasticity.
- To support the idea that protein homeostasis is a regulatory motif for synaptic plasticity.
Main Methods:
- Review of experimental data.
- Analysis of studies on mRNA translation and protein degradation.
- Focus on the ubiquitin proteasome system.
Main Results:
- Synaptic transmission involves extensive regulation of the synaptic proteome.
- Protein degradation via the ubiquitin proteasome system plays a role in synaptic plasticity.
- Protein homeostasis is a key regulatory mechanism.
Conclusions:
- Protein homeostasis is a critical regulatory motif for synaptic plasticity.
- The interplay between protein synthesis and degradation governs synaptic function.
- Understanding protein homeostasis is key to understanding synaptic plasticity and memory.

01:25Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

01:29Excitatory and Inhibitory Effects of Neurotransmitters
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...
