Lipid composition of sciatic nerve from dysmyelinating trembler mouse
Neuroscience Letters
|December 1, 1979
Summary
Lipid levels significantly decrease in trembler mouse sciatic nerves, with notable exceptions like cholesterol esters. Phospholipid alterations varied, with phosphatidylserine most affected.
Area of Science:
- Neuroscience
- Biochemistry
- Genetics
Background:
- The sciatic nerve is crucial for motor and sensory function.
- Trembler mice are a model for certain human neurological disorders.
- Lipid composition is vital for nerve structure and function.
Purpose of the Study:
- To investigate lipid alterations in the sciatic nerves of trembler mice.
- To compare lipid profiles between normal and trembler mice.
Main Methods:
- Quantitative analysis of lipid classes in sciatic nerve tissue.
- Comparison of lipid distribution in normal versus trembler mouse models.
Main Results:
- Total lipid content reduced by 66% in trembler mice compared to normal controls.
- Cholesterol esters showed a five-fold increase, contrasting with the general decrease in other lipid classes.
- Individual phospholipid levels decreased, with phosphatidylcholine least affected and phosphatidylserine most significantly altered.
Conclusions:
- Trembler mouse sciatic nerves exhibit profound lipid dysregulation.
- Specific lipid classes, such as cholesterol esters and phosphatidylserine, are uniquely impacted.
- These findings contribute to understanding the biochemical basis of neurological defects in trembler mice.
