Summary
Synapses, the brain's communication units, are not simple structures but contain specialized nanodomains. Understanding this synapse nanobiology is key to treating brain diseases like depression and schizophrenia.
Area of Science:
- Neuroscience
- Cell Biology
- Molecular Biology
Background:
- Synapses are crucial for nervous system communication, learning, and memory.
- Synaptic dysfunction underlies numerous neurological and psychiatric disorders, often termed synaptopathies.
- Previously, synapses were considered functionally indivisible due to their small size.
Purpose of the Study:
- To investigate the functional specialization within synapses at the nanoscale.
- To explore how synaptic nanobiology impacts overall brain function and disease.
- To provide a new perspective on synaptic signaling for therapeutic development.
Main Methods:
- Utilized high-resolution electrophysiology.
- Employed advanced imaging techniques.
- Analyzed synaptic nanobiology and signaling.
Main Results:
- Synapses contain functionally specialized nanomodules, challenging the view of them as indivisible units.
- Demonstrated the significance of synaptic nanobiology in information processing.
- Revealed novel insights into synaptic signaling mechanisms.
Conclusions:
- Synapses harbor specialized nanodomains that dictate their function.
- Understanding synapse nanobiology is critical for elucidating disease mechanisms.
- This research guides the development of therapeutic strategies for brain disorders.

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.

Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

02:03What is Cell Signaling?
129.9K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

11.3K
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...
