The Other Brain Cells: New Roles for Glia [Scientific American Mind]
Mercredi 28 Mai 2008 - 22:00 - 7 mois, 1 semaine depuis - Cancer - Scientific American
Neurons have always been the stars of brain research, but scientists are now realizing that nonneuronal cells known as glia--which make up around 90 percent of cells in the brain--are not the mild-mannered understudies they appeared to be. Some glia may even fire electrical signals, a finding that overturns a central dogma of neuroscience that holds that neurons are the only cells in the brain with such signaling ability.Last winter, when neuroscientists at University College London examined glia known as oligodendrocyte precursor cells (OPCs), they were astounded to find that, just like neurons, one subtype fired electrical signals in response to electrical stimulation. Before this study little was known about the function of OPCs, says study leader Ragnhildur Karadottir, except that they could develop into new oligodendrocytes, a type of glial cell that forms an insulating sheath around neurons like the rubber on an electrical cord.

New Breast Cancer Treatments Help Sufferers Gain Ground
Mardi 27 Mai 2008 - 07:20 - 7 mois, 2 semaines depuis - Cancer - Scientific American
Breast cancer is the most commonly diagnosed malignancy among women and, after lung cancer, the second leading cause of cancer-related deaths in North America. Yet unlike the survival rate for individuals diagnosed with lung cancer, the rate for women diagnosed with breast cancer has been rising dramatically over the past decade--to the point where breast cancer could soon lose its ranking as the second-greatest cancer killer. Nothing would delight clinicians like us more.This improvement in overall outlook for women diagnosed with breast cancer is attributable in part to earlier detection, which results from greater awareness of, and access to, regular breast screening. But breast cancer patients are also benefiting from accelerated research that has led to a much better understanding of the disease and a wider variety of treatment choices that doctors can mix and match to tailor therapy for a particular patient. In just the past decade, it has even become possible to target drugs to specific molecules within tumors that help to drive the disease. [More]
