...body, insulin helps convert food into cellular energy. But the brain has other uses for insulin, namely as a means to learn and make new memories. Here's how it works: At synapses, the spaces across which brain cells communicate and where memories are conceived, neurons reserve special parking spots just for insulin. When the hormone pulls in, a connection is made that enables new memories to form. Since new memory formation is one of the first things to go awry in people with early stages of the disease, this insulin-initiated process may hold the key to decoding...
...understand that the function of insulin at those synapses is to modulate and influence the underlying cellular structure of memories," says William Klein, professor of neurobiology and physiology at Northwestern University and a co-author of the study published online by the FASEB Journal. "What we have here is a striking phenomenon that may ultimately explain why the brains of people with Alzheimer's disease are insulin resistant and how that ties into memory...
...event would help break down Harvard’s “culture of mutual avoidance.” Seated casually on sofas in the Barker Center, professors shared comical anecdotes about students who came to office hours, recalling one pupil whom Professor of the Practice of Molecular and Cellular Biology Robert A. Lue nicknamed “The Ocean” for his relentless stream of questions. 300th Anniversary University Professor Laurel Thatcher Ulrich, a Pulitzer Prize-winning historian, hastened to add that students don’t need to come in with a specific question or share some...
...Gore ’69. “It’s a shame,” Sanes said. “My daughter was going to come up from college to see [chef] Alice Waters,” he added. Sanes, who is also Professor of Molecular and Cellular Biology, researches how cells and their connections in the brain become specialized. At the center, he directs a group of independent scientists as they map neurocircuits and investigate what he calls “the big intellectual question of this century.” Membership honors individual achievement, but some...
Assistant Professor of Molecular and Cellular Biology Kevin C. Eggan expressed frustration at a major stem cell conference on Tuesday about a Massachussetts law that creates roadblocks to medical research. Eggan lamented a state policy that limits access to human eggs by forbidding researchers from compensating women for egg donation. Since its inception in 2004, the Harvard Stem Cell Institute has not obtained a single egg from an eligible donor. Eggan left town immediately after the conference ended yesterday and could not be reached for additional comment. B.D. Colen, Harvard’s senior communications officer for University science, said...
