The Role of γ-Secretase Activating Protein (GSAP) and Imatinib in the Regulation of γ-Secretase Activity and Amyloid-β Generation

gamma-Secretase is a large enzyme complex comprising presenilin, nicastrin, presenilin enhancer 2, and anterior pharynx-defective 1 that mediates the intramembrane proteolysis of a large number of proteins including amyloid precursor protein and Notch. Rec ...

Highly efficient production of the Alzheimer's γ-Secretase integral membrane protease complex by a multi-gene stable integration approach

Florian Maria Wurm, David Hacker, Lorène Aeschbach, Patrick Fraering, Mitko Dimitrov, Sowmya Balasubramanian

Inefficient production of membrane-embedded multi-protein complexes by conventional methods has largely prevented the generation of high-resolution structural information and the performance of high-throughput drug discovery screens for this class of prote ...

Transgenic expression of beta 1 antibody in brain neurons impairs age-dependent amyloid deposition in APP23 mice

Maurizio Molinari

Heterologous expression of the functional amyloid beta (A beta) antibody beta 1 in the central nervous system was engineered to maximize antibody exposure in the brain and assess the effects on A beta production and accumulation in these conditions. A sing ...

Generation of monoclonal antibody fragments binding the native γ-secretase complex for use in structural studies

Patrick Fraering, Mitko Dimitrov, Lorène Aeschbach, Claude André Schweizer

A detailed understanding of γ-secretase structure is crucially needed to elucidate its unique properties of intramembrane protein cleavage and to design therapeutic compounds for the safe treatment of Alzheimer's disease. γ-Secretase is an enzyme complex c ...

Alzheimer's Disease-Linked Mutations in Presenilin-1 Result in a Drastic Loss of Activity in Purified gamma-Secretase Complexes

Patrick Fraering, Lorène Aeschbach, Jemila Houacine

Background: Mutations linked to early onset, familial forms of Alzheimer's disease (FAD) are found most frequently in PSEN1, the gene encoding presenilin-1 (PS1). Together with nicastrin (NCT), anterior pharynx-defective protein 1 (APH1), and presenilin en ...

Fluorine-18 labeling of three novel D-peptides by conjugation with N-succinimidyl-4-[F-18]fluorobenzoate and preliminary examination by postmortem whole-hemisphere human brain autoradiography

Andrea Pfeifer

Introduction: beta-Amyloid (A beta) plaques and neurofibrillary tangles are the main characteristics of Alzheimer's disease (AD). Positron emission tomography (PET), a high-resolution, sensitive, and noninvasive imaging technique, has been widely utilized ...

Selective neutralization of APP-C99 with monoclonal antibodies reduces the production of Alzheimer's Aβ peptides

Patrick Fraering, Tristan Bolmont, Lorène Aeschbach, Jemila Houacine

The toxic amyloid-β (Aβ) peptides involved in Alzheimer's disease (AD) are produced after processing of the amyloid precursor protein-C-terminal fragment APP-C99 by γ-secretase. Thus, major therapeutic efforts have been focused on inhibiting the activity o ...
