Neurotoxic β-amyloid (Aβ) peptides participate in Alzheimer’s disease (AD); therefore, reduction of Aβ generated from APP may provide a therapeutic approach for AD. Gene knockout studies in transgenic mice producing human Aβ may identify targets for reducing Aβ. This study shows that knockout of the cathepsin B gene in mice expressing human wild-type APP (hAPPwt) results in substantial decrease of Aβ40 and Aβ42 by 67% in brain, and decreases levels of the C-terminal β-secretase fragment (CTFβ) derived from APP. In contrast, knockout of cathepsin B in mice expressing hAPP with the rare Swedish (Swe) and Indiana (Ind) mutations had no effect on Aβ. The difference in reduction of Aβ in hAPPwt mice, but not in hAPPSwe/Ind mice, shows that the transgenic model can affect cathepsin B gene knockout results. Since most AD patients express hAPPwt, these data validate cathepsin B as a target for development of inhibitors to lower Aβ in AD.
