Abstract
Aim: To determine the ability of sulfated dendritic polyglycerols (dPGS) to modulate neuroglia activation challenged with lipopolysaccharide (LPS). Materials & methods: Microglia/astrocyte activation in vivo was determined in transgenic animals expressing TLR2-/GFAP-luciferase reporter. Mechanisms implicated in microglia-astrocyte crosstalk were studied in primary mouse brain cultures. Results & discussion: dPGS significantly reduced microglia activation in vivo, and decreased astrocytic LCN2 production. Activated microglia are necessary for astrocyte stimulation and increase in LCN2 abundance. LCN2 production in astrocytes involves signaling via toll-like receptor 4, activation of NF-κB, IL6 and enhancement of reactive oxygen species. Conclusion: dPGS are powerful modulators of microglia-astrocyte crosstalk and LCN2 abundance; dPGS are promising anti-inflammatory dendritic nanostructures.
期刊介绍：
The neurological landscape is changing rapidly. From the technological perspective, advanced molecular approaches and imaging modalities have greatly increased our understanding of neurological disease, with enhanced prospects for effective treatments in common but very serious disorders such as stroke, epilepsy, multiple sclerosis and Parkinson’s disease. Nevertheless, at the same time, the healthcare community is increasingly challenged by the rise in neurodegenerative diseases consequent upon demographic changes in developed countries.
