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)

Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria... view more (2005-09-22)

Adult stem cells aid recovery in animal model of cerebral palsy
Adult stem cell therapy quickly and significantly improves recovery of motor function in an animal model for the ischemic brain injury that occurs in about 10 percent of babies with cerebral palsy, researchers report.   view more (2005-10-03)

Research links 'ecstasy' to survival of key movement-related cells in brain
New research from the University of Cincinnati (UC) suggests that the widely abused club drug "ecstasy," or MDMA, can increase the survival of dopamine cells in the brain during fetal development.   view more (2006-10-19)

Man-made prostate created by women
In a giant step towards understanding prostate disease, Melbourne scientists have grown a human prostate from embryonic stem cells.   view more (2006-02-23)

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)

Bone marrow may be source of new egg-cell generation in adult mammals
Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.   view more (2005-07-28)

AIDS Drug from Sunflowers
Sunflowers can produce a substance which prevents the AIDS pathogen HIV from reproducing, at least in cell cultures.   view more (2006-01-09)

New immune cell found to be a key to inflammatory diseases
The molecular roots of inflammatory and autoimmune diseases such as asthma, arthritis, and multiple sclerosis (MS) have been discovered by a team of researchers led by The University of Texas M. D. Anderson Cancer Center.   view more (2005-10-03)

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells
Having recently identified the molecular signature of these epidermal neural crest stem cells in the mouse, their research resolves conflicting scientific opinions by showing that these cells are distinctly different from other types of skin-resident stem cells/progenitors. Their work provides a... view more (2006-12-12)

Thalidomide treatment proves better than conventional chemotherapy for multiple myeloma
When people hear "thalidomide," many think "birth defects," however, evidence has come to light that this once-banned drug can be used as a potent anti-cancer treatment. In a new study, researchers from the University of Bologna, Italy, demonstrate that Thal-Dex (thalidomide... view more (2005-06-21)

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)

Similar stem cells in insect and human gut
Scientists at the Carnegie Institution's Department of Embryology have found that adult fruitflies have the same stem cells controlling cell regulation in their gut as humans do.   view more (2005-12-08)

Study sheds light on signaling mechanism in stem cells, cancer
UCSF scientists have illuminated a key step in a signaling pathway that helps orchestrate embryonic development.   view more (2005-10-26)

Tumor cells that border normal tissue are told to leave
The thin, single-cell boundary where a tumor meets normal tissue is the most dangerous part of a cancer according to a new study by scientists at Washington University School of Medicine in St. Louis.   view more (2006-01-11)

Flatworm genes may provide insights into human diseases, researchers say
Could vital information about many human diseases be deciphered from genes inside freshwater flatworms? A definitive yes is not the answer yet, but research at the University of Illinois at Urbana-Champaign has provided an important advance for pursuing both that idea and the biology of stem cells.   view more (2005-12-14)

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)

Solar energy: Charged for the future
Once regarded as costly and impractical, solar technology is now poised to play a larger role in the future, thanks to new developments that could result in lower costs and improved efficiency.   view more (2006-09-11)

Immune system discovery could aid fight against TB
A key aspect of how the body kicks the immune system into action against tuberculosis is revealed in research published today.   view more (2006-10-23)

Killing brain tumors from within: A 'Trojan horse' approach
A new method for targeting malignant brain tumors through inducing the cancerous cells to "commit suicide" has been developed by a team of researchers headed by a Hebrew University of Jerusalem professor of biochemistry.   view more (2006-10-25)

Dangerous wheat disease jumps Red Sea
A new form of stem rust, a virulent wheat disease, has jumped from eastern Africa and is now infecting wheat in Yemen in the Arabian Peninsula.   view more (2007-01-17)

Stem cell study seeks to prevent heart failure
University of Rochester Medical Center researchers today announced the launch of a study that will examine whether transplanted stem cells can be safely used to treat damaged heart muscle in patients just after their first heart attack.   view more (2006-01-25)

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)

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)
