Motor neurons of larvae expressing Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4D42 display axonal transport defects.

Expression of Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4D42 leads to subtle morphological aberrations of larval neuromuscular junctions (NMJs) which includes the appearance of "satellite" boutons and thinning of inter-bouton regions.

Adult flies expressing Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4unspecified exhibit locomotor impairments and reduced lifespan that becomes more severe with age.

For the first 5 days post-eclosion, the climbing ability of flies expressing Scer\GAL4unspecified>Hsap\MAPTScer\UAS.1N4R does not differ from that of control flies. However, at every time point after this period, significantly fewer Hsap\MAPTScer\UAS.1N4R-expressing flies show normal climbing ability when compared with age-matched controls.

o-expression of Hsap\APPAβ42.Scer\UAS.cUa with Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4Toll-6-D42 enhances the axonal transport phenotype resulting from the expression of Hsap\MAPTScer\UAS.1N4R alone.

Co-expression of Hsap\APPAβ42.Scer\UAS.cUa with Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4Toll-6-D42 exacerbates the neuromuscular junction (NMJ) aberrations seen in mutants expressing any one of the transgenes alone, with more evidence of both "satellite" boutons and thinning of the inter-bouton regions.

Co-expression of Hsap\MAPTScer\UAS.1N4R and Hsap\APPAβ42.Scer\UAS.cUa under the control of Scer\GAL4unspecified enhances the locomotor impairment of flies expressing Scer\GAL4unspecified>Hsap\MAPTScer\UAS.1N4R alone. As the double transgenic flies age, their climbing abilities steadily deteriorate.

Co-expression of Hsap\MAPTScer\UAS.1N4R and Hsap\APPAβ42.Scer\UAS.cUa under the control of Scer\GAL4unspecified enhances the longevity phenotypes that are seen in flies expressing any of the two transgenes alone. LiCl treatment ameliorates the survival defects.

Co-expression of dshScer\UAS.T:Hsap\MYC with Hsap\MAPTScer\UAS.1N4R under the control of Scer\GAL4unspecified suppresses the axonal transport defects and locomotor impairments induced by the expression of Hsap\MAPTScer\UAS.1N4R alone.
