Summary
Perineuronal nets (PNNs) regulate metabolism and blood glucose. Factors like hormones, nutrition, and age influence PNNs, impacting overall metabolic health.
Area of Science:
- Neuroscience
- Metabolic Research
- Extracellular Matrix Biology
Background:
- Perineuronal nets (PNNs) are specialized extracellular matrix structures surrounding neurons.
- PNNs are increasingly recognized for their crucial role in regulating cellular and systemic metabolism.
- Understanding PNNs is vital for metabolic health research.
Purpose of the Study:
- To review the current understanding of PNNs in metabolic control.
- To examine the role of PNNs in energy balance and blood glucose regulation.
- To highlight novel factors influencing PNN dynamics and metabolic health.
Main Methods:
- Literature review of recent research on PNNs and metabolism.
- Analysis of studies investigating PNNs' role in energy homeostasis.
- Synthesis of findings on factors affecting PNNs, including cellular and hormonal influences.
Main Results:
- PNNs play a pivotal role in regulating whole-body energy balance and blood glucose levels.
- Astroglia, microglia, sex hormones, nutrition, circadian rhythms, and age significantly impact PNNs.
- PNNs exhibit dynamic changes influenced by various physiological and environmental factors.
Conclusions:
- PNNs are key regulators of metabolic processes.
- The multifaceted influences on PNNs underscore their complex role in metabolic health.

3.2K
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....

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

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.

The nervous system consists of complex motor neuron circuits, including upper motor neurons originating from the cerebral cortex and lower motor neurons starting in the spinal cord, coordinating both voluntary and involuntary movements. Among these, somatic motor neurons activate skeletal muscles and are classified into alpha, beta, and gamma types. Alpha neurons are vital for voluntary movement coordination, while gamma neurons adjust muscle spindle sensitivity, and the function of beta...

338
The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs.
During periods of fasting, the ENS initiates the migrating myoelectric complex, a...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
