Immunotherapy approach to Alzheimer's studied in fly models The results of using fly models to investigate passive immunotherapy to block amyloid-²42 peptides of amyloid plaques that damage the brain cells of patients with Alzheimer's disease (AD) are now presented by researchers. The scientists are investigating passive immunotherapy, one of the most promising approaches to blocking the amyloid-β42 (Aβ42) peptide, the main component of the amyloid plaques that damage the brain cells of patients with AD.
In mapping feat, scientists pinpoint neurons where select memories grow Memories are difficult to produce, often fragile, and dependent on any number of factors -- including changes to various types of nerves.

Cell-saving drugs could reduce brain damage after stroke Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries, reports a new study. The results show not only that pericytes are the main regulator of blood flow to the brain, but also that they tighten and die around capillaries after stroke. This significantly impairs blood flow in the long term, causing lasting damage to brain cells.
Key player in motor neuron death in Lou Gehrig's disease identified Amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, is marked by a cascade of cellular and inflammatory events that weakens and kills vital motor neurons in the brain and spinal cord. The process is complex, involving cells that ordinarily protect the neurons from harm. Now, a new study points to a potential culprit in this good-cell-gone-bad scenario, a key step toward the ultimate goal of developing a treatment.
