Why doesn't the immune system attack the small intestine?
Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system-perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells.   view more (2007-01-10)

2 heads are better than 1: 2 dysfunctional DNA repair pathways kill tumor cells
Individuals who inherit two mutant copies of any one of about 12 genes that make the proteins of the Fanconi Anemia (FA) pathway develop FA, which is characterized by increased incidence of cancer and bone marrow failure, among other things.   view more (2007-04-13)

High cholesterol levels are considered to be a risk factor for cardiovascular disease including stroke.   view more (2008-04-10)

Cancer cells 'reprogram' energy needs to grow and spread, study suggests
Studying a rare inherited syndrome, researchers at Johns Hopkins have found that cancer cells can reprogram themselves to turn down their own energy-making machinery and use less oxygen, and that these changes might help cancer cells survive and spread.   view more (2007-05-08)

Researchers identify key gene that may be a marker of breast cancer metastasis
Researchers at Fox Chase Cancer Center have identified an important gene involved in the spread of breast cancer that has developed resistance to long-term estrogen deprivation.   view more (2007-04-19)

Scientists find potential stem cells in amniotic fluid - a new source?
Research by Austrian geneticists has raised the possibility that stem cells[1] could be isolated from amniotic fluid - the protective 'bath water' that surrounds the unborn baby. Geneticist Professor Markus Hengstschl'¤ger and his team at the University of Vienna have isolated a subgroup of cells... view more (2003-06-27)

Scientists use stem cells to grow cartilage
Scientists from Imperial College London have successfully converted human embryonic stem cells into cartilage cells, offering encouragement that replacement cartilage could one day be grown for transplantation.   view more (2005-11-17)

Cooking with gas may increase inflammatory activity in the lungs
Cooking with gas may increase inflammatory activity in the lungs, suggests a study in Occupational and Environmental Medicine. Teflon filters were used to collect any particulate matter pollution emitted from gas and electric cookers. The residue was then applied to cultured cells that normally... view more (2001-02-10)

Discovery points to more effective ways of regulating cell signalling
A discovery made at The Walter and Eliza Hall Institute provides new insights into enhancing the function of the protein SOCS3, which regulates the response of cells to external stimuli.   view more (2006-04-21)

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells
The discoverers of the unique mouse line that is resistant to cancer have begun to pin down how the process works and found that white blood cells in these mice overwhelm normal defenses of cancer cells.   view more (2006-11-01)

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)

UT Knoxville research may lead to better flu vaccine
New research from a scientist at the University of Tennessee, Knoxville, has uncovered information that may someday lead to a better flu vaccine.   view more (2008-02-28)

Cell division studies hint at future cancer therapy
When a cell's assets get divided between daughter cells, Dr. Quansheng Du wants to make sure both offspring do well.   view more (2008-01-23)

U of M identifies cell line that is resistant to retroviruses, including HIV
Researchers at the University of Minnesota have identified a protein that enables viruses such as HIV to infect cells and spread through the body.   view more (2006-10-18)

Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs.    view more (2005-06-20)

Anti-inflammatory drug blocks brain plaques
Brain destruction in Alzheimer's disease is caused by the build-up of a protein called amyloid beta in the brain, which triggers damaging inflammation and the destruction of nerve cells.   view more (2008-06-24)

Prevention is the best option: fighting autoimmune diseases
Centenary scientist Associate Professor Barbara Fazekas de St. Groth, a leader in inflammatory bowel disease research, has demonstrated for the first time the important role of T cells in the prevention of autoimmune diseases in humans.   view more (2006-07-07)

Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis.   view more (2008-11-04)

UCLA researchers reprogram normal tissue cells into embryonic stem cells
Researchers at the Institute for Stem Cell Biology and Medicine at UCLA were able to take normal tissue cells and reprogram them into cells with the same unlimited properties as embryonic stem cells, the cells that are able to give rise to every cell type found in the body.   view more (2007-06-07)

U of M study shows why treatment isn't effective for HIV
University of Minnesota researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients.   view more (2008-08-06)

Researchers at Vanderbilt-Ingram Cancer Center uncover clue to explain invasive brain tumors
Researchers at the Vanderbilt-Ingram Cancer Center have uncovered a clue to explain the invasive nature of an aggressive kind of brain tumor called glioblastoma multiforme, or gliomas.   view more (2006-01-12)

A wandering eye
Eyes are among the earliest recognisable structures in an embryo; they start off as bulges on the sides of tube-shaped tissue that will eventually become the brain.   view more (2006-08-25)

New hope for regenerative medicine
In the February 15th issue of G&D, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice.   view more (2007-02-15)

EMC emission and immunity testing enhanced with NPL's new good practice guide on GTEM cells
Experts from the National Physical Laboratory (NPL) and York EMC Services Ltd. (YES) have jointly produced a guide on good practice techniques for EMC testing in GTEM cells. The use of GTEM cells as an EMC test environment is included in the International Standard IEC 61000-4-20 as an alternative... view more (2003-10-03)

From lung to gut - the Wnt signaling pathway transforms cell fate
Researchers have uncovered a cellular mechanism that can alter the fate of progenitor cells that normally generate the lung, causing them to create gut cells instead. The findings, which are published this week in the top-tier Open Access journal, Journal of Biology, could help researchers hoping... view more (2004-06-03)
