Abstract:
The proteolytic processing of the amyloid-beta protein precursor plays a key role in the development of Alzheimer's disease. Cleavage of the amyloid-beta protein precursor may occur via two pathways, both of which involve the action of proteases called secretases. One pathway, involving beta- and gamma-secretase, liberates amyloid-beta protein, a protein associated with the neurodegeneration seen in Alzheimer's disease. The alternative pathway, involving alpha-secretase, precludes amyloid-beta protein formation. In this review, we describe the progress that has been made in identifying the sec

Abstract:
Tumor necrosis factor-alpha converting enzyme (TACE) is the first described and best characterized secretase. In this review the structure and the possible roles for TACE are summarized. The substrate specificity and the regulation of TACE activity as well as redundancy and possible cooperations of distinct secretases are also discussed.

Abstract:
Upon spinal cord injury, axons attempting to regenerate need to overcome the repulsive actions of myelin-associated inhibitors, including the myelin-associated glycoprotein, Nogo-A, and the oligodendrocyte myelin glycoprotein. These inhibitors bind and signal through a neuronal receptor/co-receptor/transducer complex composed of NgR1, Lingo-1, and p75. Consequently, p75 is cleaved by alpha secretase followed by gamma-secretase, triggering downstream signaling that inhibits axonal regrowth. ADAM10 and ADAM17 are both known to function as alpha secretases in neurons. Here we show that ADAM17, an

Alzheimer’s disease remains a prevailing neurodegenerative condition which has an array physical, emotional, and financial consequences to patients and society. In the past decade, there has been a greater degree of investigation on therapeutic small peptides. This group of biomolecules have a profile of fundamentally sound characteristics which make them an intriguing area for drug development. Among these biomolecules, there are four modulatory mechanisms of interest in this review: alpha-, beta-, gamma-secretases, and amylin.

Abstract:
Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by cognitive decline, memory impairment, and distinct neuropathological features such as amyloid-beta (Aβ) plaques and neurofibrillary tangles. Despite extensive research, the molecular mechanisms underlying AD remain incompletely understood, posing challenges for therapeutic intervention. This review delves into the intricate processes of amyloid precursor protein (APP) processing, focusing on the roles of α-, β-, and γ-secretases in the generation of neurotoxic Aβ peptides.

AbstractAlthough Alzheimer’s disease (AD) is the most common form of dementia in the United States, development of therapeutics has proven difficult. Invertebrate alternatives to current mammalian AD models have been successfully employed to study the etiology of the molecular hallmarks of AD. The marine snail Aplysia californica offers a unique and underutilized system in which to study the physiological, behavioral, and molecular impacts of AD. Mapping of the Aplysia proteome to humans and cross-referencing with two databases of genes of interest in AD research identified 898 potential ortho

En plus d'être clivée par les β- et les γ-sécrétases lors du processus amyloïdogénique de la maladie d'Alzheimer, l'APP (Amyloid Precursor Protein) peut également subir un clivage grâce à l'α-sécrétase qui conduit à la libération des fragments d'APP soluble α (sAPPα)(voie non-amyloïdogénique) prévenant ainsi l'accumulation des peptides β-amyloïdes pathogènes. Les études sur le clivage de l'APP par l'α-sécrétase ont montré que l'activité de cette enzyme était constitutive mais aussi régulée.
