Protective effect of cactus cladode extracts on peroxisomal functions in microglial BV-2 cells activated by different lipopolysaccharides. - GreenMedInfo Summary

In this study, we aimed to evaluate the antioxidant and anti-inflammatory properties ofcactus cladode extracts in microglia BV-2 cells. Inflammation associated with microglia activation in neuronal injury can be achieved by LPS exposure. Using four different structurally and biologically well-characterized LPS serotypes, we revealed a structure-related differential effect of LPS on fatty acidβ-oxidation and antioxidant enzymes in peroxisomes:-LPS decreased ACOX1 activity while-LPS reduced only catalase activity. Different cactus cladode extracts showed an antioxidant effect through microglial catalase activity activation and an anti-inflammatory effect by reducing nitric oxide (NO) LPS-dependent production. These results suggest that cactus extracts may possess a neuroprotective activity through the induction of peroxisomal antioxidant activity and the inhibition of NO production by activated microglial cells.
