1 RESULTS: We report alpha-Syn (29-40) as a specific peptide capable of activating microglial Nox2 to produce superoxide and cause dopaminergic neuronal damage. Superoxides cytochrome b-245, beta polypeptide Mus musculus
2 Exploring the underlying mechanisms showed that alpha-Syn (29-40) peptide triggered Nox2 to generate extracellular superoxide and its metabolite H2O2 by binding to the catalytic unit gp91 (phox) of Nox2; diffusing into cytosol, H2O2 activated Erk1/2 kinase to phosphorylate p47 (phox) and p67 (phox) and further activated Nox2, establishing a positive feedback loop to amplify the Nox2-mediated response. Superoxides cytochrome b-245, beta polypeptide Mus musculus
