Qing h, zhang y, deng y, mcgeer eg, mcgeer pl kinsmen laboratory of neurological research, university of british columbia, vancouver, british columbia, canada v6t 1z3. Mutations of the leucine-rich repeat kinase 2 (lrrk2) gene are the leading cause of genetically inherited parkinson's disease (pd) and its more severe variant diffuse lewy body disease (dlb). Pathological mutations in lrrk2 are autosomal dominant, suggesting a gain of function. Mutations in alpha-synuclein also produce autosomal dominant disease. Here we report an interaction between lrrk2 and alpha-synuclein in a series of diffuse lewy body (dlb) cases and in an oxidative stress cell based assay. All five cases of dlb, but none of five controls, showed co-immunoprecipitation of lrrk2 and alpha-synuclein in soluble brain extracts. Colocalization was also found in pathological deposits in dlb postmortem brains by double immunostaining. In hek cells transfected simultaneously with plasmids expressing lrrk2 and alpha-synuclein, co-immunoprecipitation of lrrk2 and alpha-synuclein was detected when they were exposed to oxidative stress by h(2)o(2). Taken together, these results suggest the possibility that in pd and related synucleinopathies, oxidative stress upregulates alpha-syn and lrrk2 expression, paving the way for pathological interactions. viagra vision impairment New therapeutic approaches to pd and the synucleinopathies may result from limiting the interaction between lrrk2 and alpha-synuclein. best price for viagra 5 mg Mesh terms:brain, cell line, humans, immunoprecipitation, lewy body disease, oxidative stress, protein-serine-threonine kinases, rna, messenger, alpha-synuclein biochem. best price for viagra 5 mg Biophys. cheap viagra online Res. generic viagra canada Commun.
