Is Presenilin-1 Really Guilty of Dismembering Alzheimer Protein?
Douglas Steinberg | Oct 27, 2002 | 4 min read
Image: Courtesy of Yue-Ming Li  HOW PHOTOACTIVATION WORKS: When a benzophenone group is attached to a g-secretase inhibitor and exposed to light, the benzophenone's oxygen turns into a triplet biradical, which bonds covalently with a nearby protein. Many neuroscientists think that the master criminal behind Alzheimer disease is AB-secretase-42, the 42-amino-acid peptide that forms amyloid plaques in the brain. Two accomplices, the enzymes B-secretase-secretase and g-secretase, consecutiv
Elusive Gamma-Secretase Identified

Model of an inhibitor targeted to g-secretase interacting with presenilin. The background shows an Alzheimer's brain that carried a presenilin mutation, with immunohistochemistry revealing abundant amyloid plaques (red-orange patches). For years researchers have been perplexed by the identity of g-secretase, an enzyme that cuts amyloid precursor protein (APP) into amyloid ß (Aß) fragments that form telltale plaques in the brains of Alzheimer's patients. Now researchers from Merck Rese

STRIKING RESEMBLANCE: James Croom, who studies Down syndrome mice at North Carolina State University, says the animals are providing valuable information useful to humans. When a page-one article in the May 3, 1998, Sunday New York Times portrayed angiogenesis inhibitors that fight cancer in mice as being possible just around the corner for humans, criticism for raising false hopes erupted. Merely 10 weeks later, however, when researchers from the University of Hawaii reported cloning the fi

Sidebar: Society for Neuroscience NEW MESSENGERS: Caltech’s Erin Schuman and colleagues discovered that one form of nitric oxide is important to long-term potentiation. Can you recall where you were when you heard about the explosion of the space shuttle Challenger? Why is it that, almost universally, people can remember with vivid and instantaneous detail this tragic event when they can't recall what they had for dinner just days before? How are some memories indelibly hard-wired into o
