From: LRRK2 activity does not dramatically alter α-synuclein pathology in primary neurons

Fig. 1

G2019S LRRK2 hippocampal neurons do not have elevated α-synuclein pathology 14 days post-transduction. a Primary hippocampal neurons from NTG or G2019S pups were transduced with 2.5 μg/mL α-synuclein PFFs and allowed to age a further 14 days prior to sequential detergent fractionation. TX-100-insoluble α-synuclein and p62 are similar in both neuron types. b Quantification of soluble proteins shows ~ 25-fold elevation in the expression of LRRK2 and a commensurate ~ 50-fold elevation in pS395 LRRK2, indicative of the elevated LRRK2 kinase activity associated with the G2019S mutation. Soluble α-synuclein levels were equivalent between the cultures. c No significant differences were found between the genotypes in insoluble proteins by an unpaired t-test with Welch’s correction. (N = 3 biological replicates for each protein). Means + s.e.m.; **P < 0.01; *P < 0.05 by an unpaired t-test with Welch’s correction for unequal variances. All values are normalized to NTG neurons treated with α-synuclein PFFs and DMSO
