In Germany alone, more than 300,000 people are afflicted by Parkinson's disease and the number is growing steadily. However, despite comprehensive research, scientists are still somewhat in the dark as to the molecular changes that trigger this illness. Scientists at the Max Planck Institute of Neurobiology in Martinsried, Germany, together with colleagues from Munich and Hamburg, have demonstrated using a new animal model that nerve cells do not begin to die to the extent found in...

Animal study furthers our understanding of inherited neurodegenerative disease New research shows how a mutation causes a common inherited neurodegenerative disease, according to a study in the March 24 issue of The Journal of Neuroscience. The study shows that the mutation of a specific protein known to cause Charcot-Marie-Tooth (CMT) disrupts the movement of mitochondria, the energy-supplying machines inside each cell. The regulated movement of mitochondria along nerve cell fibers is vital...

A discovery by Newcastle University experts could provide the next step in fighting age related diseases, such as diabetes and heart disease. Scientists from the University's Institute for Ageing and Health have used state-of-the-art laboratory techniques and sophisticated mathematical modelling to help crack the problem of why cells age. The ageing process has its roots deep within the cells and molecules that make up our bodies and experts have identified the molecular pathway that reacts...

Enforcing new Chinese rules for clinics may impact lucrative stem cell therapy tourism but improve international credibility, confidence Chinese researchers have become the world's fifth most prolific contributors to peer-reviewed scientific literature on clock-reversing regenerative medicine even as a skeptical international research community condemns the practice of Chinese clinics administering unproven stem cell therapies to domestic and foreign patients. According to a study by the...

FINDINGS: Several structurally similar small molecules appear capable of protecting cells from alpha-synuclein toxicity, a hallmark of Parkinson's disease. RELEVANCE: Parkinson's disease is a neurodegenerative disorder characterized by tremors, muscle rigidity, and slowed movements. There is currently no cure for the disease, and current Parkinson's therapies only address disease symptoms, not the disease's cellular cause. Small molecules found to protect cells in multiple models of...

Scientists at Brown University and the California Institute of Technology have for the first time tracked how cells move in three dimensions by measuring the force exerted by them on their surroundings. The scientists' experiments revealed that cells move in a push-pull fashion, such as probing at depth, redistributing weight at various points and coiling and elongating. Results appear online in the Proceedings of the National Academy of Sciences. Our cells are more like us than we may think....

Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss. Now a University of Florida team and researchers from University of Wisconsin and three other institutions have identified a protein that is central to processes that cause oxidative damage to cells and lead to age-related hearing loss. The findings help point the way toward a new target for antioxidant...

Becoming "hard of hearing" is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030. "Age-related hearing loss is a very common symptom of aging in humans, and also is universal among mammal species, and it's one of the earliest detectable sensory changes in aging," says Tomas Prolla, a professor of genetics and medical genetics at the...

A gene associated with longevity in roundworms and humans has been shown to affect the function of stem cells that generate new neurons in the adult brain, according to researchers at the Stanford University School of Medicine. The study in mice suggests that the gene may play an important role in maintaining cognitive function during aging. "It's intriguing to think that genes that regulate life span in invertebrates may have evolved to control stem cell pools in mammals," said Anne Brunet,...
