New Study Shows that Fetal Cells Transplanted into the Brain to Treat Parkinson's Disease May Not Function Long Term
Neurons grafted into the brain of a patient with Parkinson's disease fourteen years ago have developed Lewy body pathology, the defining pathology for the disease, according to research by Jeffrey H. Kordower, PhD, and associates and published in the April 6 issue of Nature Medicine. view more (2008-04-07)
Body's immune system response to dental plaque varies by gender and race
Will neglecting to brush your teeth damage more than just your smile? Can failing to attack dental plaque increase your risk of heart damage? view more (2009-09-25)
One step closer to an artificial nerve cell
Scientists at the Swedish medical university Karolinska Institutet and Linköping University are well on the way to creating the first artificial nerve cell that can communicate specifically with nerve cells in the body using neurotransmitters. view more (2009-07-08)
Boston College profs study oxidative stress subcellular to discover its role in diseases
Oxidative stress is known to underlie many human diseases including atherosclerosis, Parkinson's disease and Alzheimer's disease. view more (2007-09-17)
Carnegie Mellon researcher proposes development of artificial cells to fight disease
Carnegie Mellon University's Philip LeDuc predicts the use of artificially created cells could be a potential new therapeutic approach for treating diseases in an ever-changing world. view more (2007-02-08)
Enzyme may be a key to Alzheimer's-related cell death
A Purdue University researcher has discovered that the amount of an enzyme present in neurons can affect the mechanism thought to cause cell death in Alzheimer's disease patients and may have applications for other diseases such as stroke and heart attack. view more (2009-10-08)
Yale researchers discover Legionnaire microbe's tricks
Yale University researchers have shed new light how bacteria like the ones that cause Legionnaires' disease and Q-fever raise such havoc in human patients. view more (2008-06-20)
New cancer drug possible from compound found in common food.
A compound found in many foods and drinks could form the basis for new drugs to defeat cancer and heart disease, scientists at UCL claimed today. Professor Peter Shepherd and his team believe that caffeine and theophylline- compounds commonly found in cola beverages, coffee, tea and chocolate - block the operation of a key enzyme linked to a wide... view more...

Rong Li Lab demonstrates the process of mammalian egg maturation
he Rong Li lab team has answered an important question about how mammalian eggs undergo maturation through an intricate process of asymmetric cell division. The team discovered a novel pathway by which chromatin exerts command on the cell membrane to produce a specialized machinery used for cell division. view more (2007-02-06)
Drug resistance may travel same path as quorum sensing
The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing. view more (2006-02-07)
Cell Therapy for Parkinson's Disease
According to research work at the University Hospital, cell therapy could improve many of the motor deficits of patients with Parkinson's Disease. view more (2004-05-03)
Study shows how daughter is different from mother
The mother-daughter relationship can be difficult to understand. Why are the two so different? Now a Northwestern University study shows how this happens. In yeast cells, that is. view more (2008-08-19)
Human stem cells provide a new model for Lou Gehrig's disease
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a devastating condition in which motor neuron degeneration causes progressive loss of movement and muscle tone, leading to death. view more (2009-02-23)
Investigators unveil new drug discovery tool for Alzheimer's disease
An article published in the April issue of the Journal of Alzheimer's Disease presents a detailed characterization of a new drug discovery tool for Alzheimer's disease. view more (2008-04-29)
Breast stem cells have features similar to 'basal' tumors
The most aggressive form of breast cancer may originate from breast stem cells that have undergone genetic mishaps. view more (2006-07-20)
Scientists on track for early diagnosis of neurological diseases
Possible treatments for fatal neurodegenerative diseases such as CJD, Alzheimer's, Parkinson's could result from University of Edinburgh research to find out how specific proteins cause deterioration in brain function. The scientists have discovered for the first time that protein 14-3-3 plays a key role in the development of certain brain... view more... (2003-07-01)
The development of stem cells -- not only which and where but also WHEN
Yet another stride has been taken on the road to knowledge about the development of the nervous system. For the first time factors have been uncovered that decide when a cell is to develop into another cell. During the last ten years much progress has been made in finding out what determines how various types of nerve cells develop from a stem... view more... (2003-03-20)
A new jump start for aging blood vessels
Recent studies show promise for significantly reducing vascular aging by inactivating TNFa, which has been linked to blood vessel dysfunction and cell death. The related report by Csiszar et al., "Vasculoprotective effects of anti-TNFa treatment in aging," appears in the January issue of The American Journal of Pathology. view more (2006-12-28)
Isolation of a new gene family essential for early development
Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute sig-nificantly to the understanding of the development of cancer. view more (2007-08-23)
Scientists develop novel method to generate functional hepatocytes for drug testing
Scientists have for the first time produced liver cells from adult skin cells using the induced pluripotent stem cell (iPSC) technology. view more (2009-10-21)
