Other Comments

Expression of Hsap\APP in Drosophila induces AICD-dependent cell death and a locomotion defect.

Expression of Hsap\APP is able to induce cell death in non-neuronal tissues during development.

The ability of Xbp1 overepxression and loss-of-function alleles to modify Hsap\APP neurotoxicity in the eye suggests that Xbp1 plays a key role in Hsap\APP pathobiology.

Expression of Mmus\Xbp1 reduces Hsap\APP neurotoxicity without altering Aβ levels and aggregation.
