Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
Possible new compound for treatment of cerebral malaria
In a paper published online in PLoS Medicine researchers from Marseille describe the effects of a new compound that may be a future treatment for patients with cerebral malaria. view more (2005-08-23)
Stem cell identity in culture may strongly depend on the cellular microenvironment
Identification, isolation and large scale culture of stem cells for potential medical applications is a major challenge in cell biology. view more (2007-04-25)
Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years. view more (2005-10-13)
U of MN researchers use human embryonic stem cells to kill cancer cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors). view more (2005-10-12)
'Underground' tunnels discovered as means for communication between immune system cells
Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells. view more (2005-09-21)
Tumor cells evade death through autophagy
Autophagy is a cellular process that enables cells to turnover their contents, something that they do frequently. Autophagy is initiated in tumor cells by chemotherapy and radiation, but it is not known if this contributes to tumor cell death or helps tumor cells survive the anti-cancer therapy. view more (2007-01-19)
How to design a cancer-killing virus
One new way to treat individuals with cancer that is being developed is the use of viruses that infect and kill cancer cells while leaving normal cells unharmed. view more (2007-10-26)
Study finds novel vaccine curbs brain tumor growth, increases survival
A novel vaccine has significantly increased life expectancy in patients with glioblastoma multiforme (GBM), the most dangerous type of brain tumor. view more (2006-04-26)
U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells. view more (2006-02-14)
Scientists show how thinking can harm brain cells
Scientists at the University of Rochester Medical Center have targeted a new culprit and method of attack on neurologic functions in diseases such as Alzheimer's and dementia associated with HIV. view more (2005-11-04)
Researchers find molecule that may hold key to learning and memory
Independent research teams from Harvard Medical School and Children's Hospital Boston have identified a master protein that sheds light on one of neurobiology's biggest mysteries-how neurons change as a result of individual experiences. view more (2006-02-22)
Could skin cells become brain cells? (p 172)
Results of an experimental study in this week's issue of THE LANCET highlight how adult skin cells can be made into precursor nerve cells, with potential implications for the future treatment of neurodegenerative disorders such as Parkinson's disease. Ethical and practical considerations limit the availability of neural stem cells derived from... view more... (2004-07-07)
MIT researcher finds neuron growth in adult brain
Despite the prevailing belief that adult brain cells don't grow, a researcher at MIT's Picower Institute for Learning and Memory reports in the Dec. 27 issue of Public Library of Science (PLoS) Biology that structural remodeling of neurons does in fact occur in mature brains. view more (2005-12-27)
New stem-cell findings can help the body to cure itself
Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell. The study is published in the latest issue of the prestigious scientific journal, Cell. view more (2006-06-16)
Antibiotics may not be enough to stop recurrent gastric lymphoma caused by Helicobacter pylori
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind. view more (2005-08-25)
Hormonal signaling in the brain: radical shift in understanding information processing
Two University of Edinburgh professors from the Centre for Integrative Physiology describe how "our understanding of how the brain processes information is undergoing a radical shift as we begin to recognize the implications of hormonal signaling systems within the brain itself," explained Gareth Leng. view more (2005-07-20)
Proteins anchor memories in our brain
A University of Utah study suggests that memories are held in our brains because certain proteins serve as anchors, holding other proteins in place to strengthen synapses, which are connections between nerve cells. view more (2006-11-22)
Researchers identify major source of muscle repair cells
In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair. view more (2006-01-30)
New U of T strategy will boost cord blood stem cells
A team of bioengineers led by the University of Toronto has discovered a way to increase the yield of stem cells from umbilical cord blood, to an extent which could broaden therapeutic use of these cells. view more (2005-10-19)
