Finally, some patients express mutant presenilin proteins 1 and 2 (PS1 and PS2) that can change the processing of APP by altering gamma secretase activity, thereby promoting the generation of amyloidogenic Abeta (Hardy and Selkoe, 2002). PubMed:14556719

Cellular cholesterol can directly impact the level of Aβ, as decreases in cholesterol levels inhibit the generation of Aβ peptides through direct modulation of γ-secretase activity [78,79]. PubMed:29758300

The finding of reduced Aβ generation when conversion of sphingomyelin to ceramide is blocked further substantiates the crucial involvement of sphingolipids in Aβ metabolism through modulation of γ-secretase [81,82] PubMed:29758300

A recent line of work revealed Aβ-promoting function of PICALM by demonstrating that PICALM depletion decreased Aβ generation through disrupting clathrin-mediated endocytosis and internalization of γ-secretase [99,100]. PubMed:29758300

Recent studies have unveiled a novel role of NF-κB in the regulation of the γ-secretase activity mediated processing of the C99 (CTFβ) fragment PubMed:28745240

In addition to augmenting γ-secretase activity, NF-κB also regulates the expression of the PS1 subunit of the γ-secretase complex PubMed:28745240

Concomitant cleavage of APP by beta and gamma secretase at specific sites can result in fragments (Abeta1-40 or Abeta1-42) that can misfold and form extracellular fibrils. PubMed:14556719

Aβ peptides originate from the transmembrane protein amyloid precursor protein (APP) which undergoes sequential cleavage via two distinct pathways by the enzyme complexes β- and γ-secretase [31] PubMed:29758300
