Study of the natural cactus extracts protective effects on oxidative stress and inflammation related to peroxisomal β-oxidation deficiencies

2023

The objective of my thesis work was to better understand the role of microglial cells in neuroinflammation initiated in several neurovegetative peroxisomal leukodystrophies and to explore the protective effects of substances from the cactus Opuntia ficus indica. To this end, we used as an in vitro model microglial cells deficient in ATP Binding Cassette D transporters (ABCD 1 and ABCD 2) or acyl-CoA oxidase 1 (ACOX1). These are two BV-2 murine cell lines, deficient in Abcd1/Abcd2-/- or deficient in Acox1-/-, obtained elsewhere by gene editing using the CRISPR/Cas9 methodology. Our results made it possible to: (i) characterize, by differential centrifugation and isopycnic ultracentrifugation…
