简介：
Overview
This article presents protocols to study the neurovascular unit impairment during experimental autoimmune encephalomyelitis (EAE) in vivo. It focuses on assessing blood-brain barrier permeability and gelatinase activity related to leukocyte migration.
Key Study Components
Area of Science
- Neuroscience
- Immunology
- Experimental Models
Background
- Experimental autoimmune encephalomyelitis is a model for multiple sclerosis.
- Understanding immune cell migration across brain barriers is crucial for neuroinflammatory research.
- Blood-brain barrier integrity is vital for maintaining central nervous system homeostasis.
- Matrix metalloproteinases play a role in leukocyte infiltration during neuroinflammation.
Purpose of Study
- To investigate the molecular mechanisms of immune cell migration in EAE.
- To correlate blood-brain barrier permeability with immune cell infiltration.
- To link neuroinflammatory events with clinical signs of EAE.
Methods Used
- Use of C57-Black/6 mice in specific-pathogen-free conditions.
- Subcutaneous injection of MOG peptide and complete Freund's adjuvant.
- Assessment of blood-brain barrier permeability.
- Evaluation of matrix metalloproteinase activity.
Main Results
- Demonstrated correlation between blood-brain barrier permeability and immune cell infiltration.
- Identified the role of gelatinase activity in leukocyte migration.
- Established a link between neuroinflammatory processes and clinical manifestations of EAE.

What is experimental autoimmune encephalomyelitis?
EAE is an animal model used to study multiple sclerosis and neuroinflammation.
Why is blood-brain barrier permeability important?
It is crucial for understanding how immune cells infiltrate the central nervous system during neuroinflammation.
What role do matrix metalloproteinases play?
They are involved in the degradation of extracellular matrix components, facilitating leukocyte migration.
How are the experimental procedures conducted?
Mice are anesthetized and injected with MOG peptide and adjuvant to induce EAE.
What are the clinical signs of EAE?
Clinical signs can include motor deficits, paralysis, and other neurological symptoms.
What is the significance of this research?
It provides insights into the mechanisms of neuroinflammation and potential therapeutic targets for multiple sclerosis.
