The metalloprotease ADAMTS4 generates N-truncated A4-x species and marks oligodendrocytes as a source of amyloidogenic peptides in Alzheimer's disease

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Sandra Lehmann

Brain accumulation and aggregation of amyloid- (A) peptides is a critical step in the pathogenesis of Alzheimer's disease (AD). Full-length A peptides (mainly A1-40 and A1-42) are produced through sequential proteolytic cleavage of the amyloid precursor pr ...

Zinc and Copper Differentially Modulate Amyloid Precursor Protein Processing by -Secretase and Amyloid- Peptide Production

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Guillermo Miguel Garcia Osuna

Recent evidence suggests involvement of biometal homeostasis in the pathological mechanisms in Alzheimer's disease (AD). For example, increased intracellular copper or zinc has been linked to a reduction in secreted levels of the AD-causing amyloid- peptid ...

Regulated intramembrane proteolysis of the AXL receptor kinase generates an intracellular domain that localizes in the nucleus of cancer cells

Patrick Fraering

Deregulation of the TAM (TYRO3, AXL, and MERTK) family of receptor tyrosine kinases (RTKs) has recently been demonstrated to predominately promote survival and chemoresistance of cancer cells. Intramembrane proteolysis mediated by presenilin/gamma-secretas ...

The lipidome associated with the gamma-secretase complex is required for its integrity and activity

Henning Paul-Julius Stahlberg, Patrick Fraering, Hermeto Gerber, Guillermo Miguel Garcia Osuna

gamma-Secretase is a multi-subunit membrane protease complex that catalyses the final intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of amyloid-beta peptides (A beta), which are implicated as the causative ...

Inhibition of Notch pathway arrests PTEN-deficient advanced prostate cancer by triggering p27-driven cellular senescence

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Maria Luna Perciato, Jingjing Chen, Andrea Rinaldi

Activation of NOTCH signalling is associated with advanced prostate cancer and treatment resistance in prostate cancer patients. However, the mechanism that drives NOTCH activation in prostate cancer remains still elusive. Moreover, preclinical evidence of ...

Shedding of neurexin 3 beta ectodomain by ADAM10 releases a soluble fragment that affects the development of newborn neurons

Patrick Fraering, Erika Myrna Borcel Novoa, Mitko Dimitrov, Magda Maria Palczynska, Giorgio Ulrich, Marine Krzisch

Neurexins are transmembrane synaptic cell adhesion molecules involved in the development and maturation of neuronal synapses. In the present study, we report that Nrxn3 beta is processed by the metalloproteases ADAM10, ADAM17, and by the intramembrane-clea ...

Detection of Alzheimer’s disease amyloid-beta plaque deposition by deep brain impedance profiling

Philippe Renaud, Patrick Fraering, Sébastien Mosser, Pierre Joris, Amélie Barbara Hildegarde Béduer

OBJECTIVE: Alzheimer disease (AD) is the most common form of neurodegenerative disease in elderly people. Toxic brain amyloid-beta (ASS) aggregates and ensuing cell death are believed to play a central role in the pathogenesis of the disease. In this study ...

A Simple and Reliable PDMS and SU-8 Irreversible Bonding Method and Its Application on a Microfluidic-MEA Device for Neuroscience Research

Philippe Renaud, Arnaud Bertsch, Marc Olivier Heuschkel, Patrick Fraering, Sébastien Mosser, Yufei Ren, Shun-Ho Huang, Jingjing Chen

Polydimethylsiloxane (PDMS) and SU-8 are currently two very commonly used polymeric materials in the microfluidics field for biological applications. However; there is a pressing need to find a simple, reliable, irreversible bonding method between these tw ...

The adipocyte differentiation protein APMAP is an endogenous suppressor of Aβ production in the brain

Bernard Schneider, Patrick Fraering, Mitko Dimitrov, Sébastien Mosser, Justine Pascual, Alexandre Matz

The deposition of amyloid-beta (Aβ) aggregates in the brain is a major pathological hallmark of Alzheimer's disease (AD). Aβ is generated from the cleavage of C-terminal fragments of the amyloid precursor protein (APP-CTFs) by γ-secretase, an intramembrane ...
