Abstract
Inflammatory conditions mediated by activated microglia lead to chronic neuro-degenerative diseases such as Alzheimer's, Parkinson's, and Huntington's diseases. This study was conducted to determine the effect of floridoside isolated from marine red algae Laurencia undulata on LPS (100 ng/ml) activated inflammatory responses in BV-2 microglia cells. The results show that floridoside has the ability to suppress pro-inflammatory responses in microglia by markedly inhibiting the production of nitric oxide (NO) and reactive oxygen species (ROS). Moreover, floridoside down-regulated the protein and gene expression levels of iNOS and COX-2 by significantly blocking the phosphorylation of p38 and ERK in BV-2 cells. Collectively, these results indicate that floridoside has the potential to be developed as an active agent for the treatment of neuro-inflammation.
