Synaptic Signaling

81.7K
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.

Synaptic Signaling

7.1K
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.
The presynaptic neuron fires an action potential that...

Neuron Structure

21.2K
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.

Neuronal Communication01:28

Neuronal Communication

5.0K
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

The Role of Ion Channels in Neuronal Computation

4.2K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Summary

The DCC receptor protein anchors translation machinery at the neuron's plasma membrane. Upon netrin binding, DCC releases these components, initiating localized protein synthesis in response to external signals.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Cell Biology

Background:

  • Investigating the mechanisms linking neuronal protein synthesis to extracellular cues.
  • Understanding how cells regulate gene expression in response to external stimuli.

Discussion:

  • The study reveals the crucial role of the Deleted in Colorectal Carcinoma (DCC) receptor in coordinating protein synthesis.
  • DCC acts as a scaffold, tethering translation machinery components to the neuronal plasma membrane.

Key Insights:

  • Netrin binding to DCC triggers the localized release of translation factors.
  • This release initiates spatially restricted protein synthesis, a key process in neuronal function.
  • Demonstrates a direct link between extracellular signaling and the initiation of protein synthesis.
