The blood-brain barrier (BBB) becomes hyperpermeable in neurodegenerative diseases like ALS, potentially driving disease progression. This review explores BBB dysfunction and therapeutic strategies for these conditions.
Area of Science:
- Neuroscience
- Immunology
Background:
- The blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) regulate the central nervous system microenvironment.
- These barriers are crucial for neuronal function, nutrient supply, waste removal, and immune privilege.
Purpose of the Study:
- To review evidence suggesting BBB hyperpermeability as a disease-driving factor in amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.
- To discuss factors influencing BBB permeability in these conditions.
Main Methods:
- Literature review of studies investigating BBB function in neurodegenerative diseases.
- Analysis of biochemical, physiological, and genomic factors affecting BBB permeability.
Main Results:
- Evidence indicates BBB hyperpermeability in ALS and related neurodegenerative conditions.
- BBB dysfunction allows detrimental molecules to enter the central nervous system, exacerbating disease.
Conclusions:
- BBB hyperpermeability is a significant contributor to ALS and neurodegenerative disease pathology.
- Targeting the BBB presents a promising therapeutic avenue for these debilitating diseases.
