Fifth, mutations in APP similarly disrupt endosomal and lysosomal func- tion, in part owing to accumulation of the β-secretase- generated, carboxy-terminal and Aβ42-containing fragment of APP called C99 (REF.66) . PubMed:30116051

In this regard, elevated bCTF levels induced by APP overexpression, elevated dietary cholesterol, or overexpression of its receptor ApoE (particularly ApoE 14) can upregulate endocytosis and enlarge endosomes (Laifenfeld et al. 2007; Chen et al. 2010; Cossec et al. 2010), leading to impaired endosome retrograde transport (S Kim and RA Nixon, unpubl.).

Still other cargoes reach late endosomes when Rab7 and its effectors replace Rab5 and initiate further endosomal maturation (Poteryaev et al. 2010). PubMed:22908190

Beyond influencing Ab generation and toxicity, defective endosome functioning plays a crucial Ab-independent role in the failure of retrograde NGF signaling that leads to basal forebrain cholinergic neuron degeneration in the Ts65Dn mouse model of DS (Cooper et al. 2001; Delcroix et al. 2004).
