Summary
Ascorbic acid (AA) significantly accelerates nerve regeneration after injury by promoting axonal regrowth and improving nerve function. This essential nutrient enhances the recovery of neurons, Schwann cells, and macrophages, aiding nerve repair.
Area of Science:
- Neuroscience
- Regenerative Medicine
- Biochemistry
Background:
- Ascorbic acid (AA) is a vital micronutrient with established clinical safety.
- Its role in nerve regeneration has not been previously explored.
Purpose of the Study:
- To investigate the potential of ascorbic acid (AA) in promoting peripheral nerve regeneration.
- To elucidate the cellular mechanisms underlying AA's effects on nerve repair.
Main Methods:
- A mouse model of sciatic nerve crush injury was utilized.
- Immunostaining, Western blotting, histomorphometry, behavioral tests, and electrophysiological assays were performed.
- In vitro studies assessed AA's effects on cultured neurons, Schwann cells, and macrophages.
Main Results:
- Ascorbic acid (AA) significantly accelerated axonal regrowth and improved nerve structure and function post-injury.
- AA treatment alleviated muscle atrophy and enhanced motor and sensory recovery.
- AA promoted neurite growth in neurons, enhanced Schwann cell proliferation and function, and improved macrophage responses.
Conclusions:
- Ascorbic acid (AA) effectively promotes morphological and functional recovery of injured peripheral nerves.
- AA's pro-regenerative effects are mediated through beneficial impacts on neurons, Schwann cells, and macrophages.

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

1.2K
The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

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.
