Could Antibodies or Hormones Slow Brain Damage from Alzheimer’s?
Scientists have discovered that certain antibodies may help slow the progression of Alzheimer’s disease. Dr. Patricia Salinas of University College London, UK, and her team focused on a protein called Dkk1, present in raised levels in the brains of people with Alzheimer’s disease. Using brain samples from mice, the team looked at the progressive disintegration of synapses in the hippocampus when exposed to a protein called amyloid-beta, thought to be central to the development of Alzheimer’s disease. “Synaptic loss mediated by amyloid-beta in early stages of the disease might contribute to cognitive...

Identification of novel cis-regulatory regions from the Notch receptor genes lin-12 and glp-1 of Caenorhabditis elegans.
Abstract Notch signaling regulates various cellular processes such as growth, proliferation and differentiation, and plays a key role in tissue patterning during animal development. In humans, defects in Notch signaling have been implicated in cancer, stroke, neurodegeneration, as well as learning and memory deficits. The genome of the nematode Caenorhabditis elegans encodes two members of the Notch transmembrane receptor family, LIN-12 and GLP-1, which have both unique and shared developmental functions. LIN-12 affects diverse cell fate specification events at certain embryonic and larval stages, including the AB...
