Exploring the Connectivity of Neurodegenerative Diseases: Microglia as the Center

Area of Science:

• Neuroscience
• Immunology
• Pathology

Background:

• Degenerative diseases pose significant health and social challenges.
• Microglia, the central nervous system's immune cells, play a crucial role in disease pathogenesis.
• Understanding microglia mechanisms is key to developing effective treatments.

Purpose of the Study:

• To review the mechanisms of microglia in various degenerative diseases.
• To examine the impact of microglia inhibitors and activators.
• To highlight microglia's dual role in inflammation and disease progression.

Main Methods:

• Literature review of studies on microglia in neurodegenerative diseases, age-related hearing loss, Alzheimer's disease, Parkinson's disease, and peripheral nervous system disorders.
• Analysis of research on microglia modulators like PLX3397/PLX5622 and lipopolysaccharide.

Main Results:

• Microglia are implicated in the pathogenesis of diverse degenerative conditions.
• Inhibiting microglia (e.g., with PLX3397/PLX5622) shows potential in curbing disease genesis and progression.
• Microglia exhibit both anti-inflammatory and pro-inflammatory functions, critical in central and peripheral diseases.

Conclusions:

• Modulating microglia activity, particularly reducing their detrimental effects, offers a promising therapeutic strategy for degenerative diseases.
• Targeting microglial cells presents a viable avenue for future treatments, despite their complex nature.
