Periodontitis and plasma C-reactive protein during pregnancy

Researchers found that pregnant women with periodontitis had 65 percent higher C-reactive protein (CRP) levels compared to periodontally healthy women.

Identification of CPT1c gene that the brain needs to manage body weight

Working with genetically engineered mice, Johns Hopkins scientists have interfered with the brain's ability to control an animal's response to a high-fat diet.

Study looks at the cellular basis for immune activation in fatigued breast cancer survivors

Breast cancer survivors who suffer from persistent, debilitating fatigue years after their diagnosis have something in common: their immune systems don't shut down following treatment, according to researchers at UCLA's Jonsson Cancer Center.

Study highlights the benefits of a clinic that specializes in the needs of obese patients with metabolic syndrome

Obesity researchers at the Medical College of Wisconsin in Milwaukee found that a multidisciplinary clinical approach to caring for obese patients with metabolic syndrome could swiftly and significantly lower their risk for heart disease.

New vaccine against lethal avian influenza virus shows promise

A commercially developed vaccine has successfully protected mice and ferrets against a highly lethal avian influenza virus, according to the investigator who led the study at St. Jude Children's Research Hospital.

Protein produced by immune cells during malaria infection triggers severe anemia

Richard Bucala and colleagues at Yale University show that immune cells in mice with malaria secrete a protein called MIF, which decreases the production of red blood cells (RBCs) from the bone marrow. The study appears in The Journal of Experimental Medicine.

Epstein-Barr virus may trigger multiple sclerosis

Researchers have found that patients with multiple sclerosis (MS) carry a population of immune cells that overreact to Epstein-Barr virus.

Potentially powerful tool for designing novel Alzheimer's treatments

Researchers have identified a protein that reins in the rogue activity of the molecules that make the amyloid-beta protein--which may prevent normal brain function in people with Alzheimer's disease. Their findings reveal a potentially powerful tool for designing novel Alzheimer's treatments.

Possible target for future therapies aimed at delaying or stopping Alzheimer's disease

Researchers at Oregon Health & Science University's Neurological Sciences Institute (NSI) have located a possible target for future therapies aimed at delaying or stopping Alzheimer's disease.

Method by which Caspase-12 shuts down the body's immune system discovered

Caspase-12 is a molecule with a death-wish. Found only in people of African descent, this protein shuts down our body's immune system, opening the door to potentially lethal infections. In a groundbreaking new study published in the prestigious journal Nature this week, the team that first discovered the role of caspase-12 in humans has now uncovered the mechanism by which it sabotages us, allowing researchers to develop methods to counter its damaging effects.

Tumour specific drugs may render therapies based on a tumor's anatomical location obsolete

The results of a new study at Washington University School of Medicine in St. Louis could eventually have oncologists removing their specialties from their shingles by making therapy based on a tumor's anatomical location obsolete.

Amyloid protein content in the brain linked to Alzheimer's disease risk

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are the first to show that the quantity of amyloid protein in brain cells is a major risk factor for Alzheimer's disease. Amyloid protein has already been known to be the primary component of the senile plaques in the brains of patients. The new discovery demonstrates that the greater the quantity of the protein that is produced, the younger the dementia patient is.

Enzyme discovery could reduce Kaposi sarcoma tumour growth and lead to drugs suitable for treating other viral cancers

A report in the Journal of Biological Chemistry shows that inhibition of heme oxygenase-1, an enzyme involved in iron metabolism, reduces Kaposi sarcoma tumor growth. This discovery could result in the production of new drugs to treat this and other viral cancers.

Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

Researchers figure out how nuclear pores duplicate before cells divide

Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. Now, for the first time, scientists at the Salk Institute for Biological Studies watched as new funnel-like pore structures formed from scratch, and inserted themselves into the nuclear membrane.

Polycomb proteins key factors in influencing the direction of embryonic stem cell development

Embryonic stem cells may one day provide a means to treat disease, but according to two new reports, they are already revealing remarkable insights into the mysteries of human biology. How humans manage to develop from a single fertilized egg into the trillions of cells that make up a mature adult remains a poorly understood process. Now, using both human and mouse embryonic stem cells, researchers have mapped how a key developmental ingredient controls the genome.

Discovery brings embryonic stem cell medicine a step closer

A team of scientists announced a critical step on the path of realizing the promise of embryonic stem (ES) cells for medicine. The researchers have discovered unique molecular imprints coupled to DNA in mouse ES cells that help explain the cells' rare ability to form almost any body cell type. These imprints, or "signatures," appear near the master genes that control embryonic development and probably coordinate their activity in the early stages of cell differentiation. Not only do these findings help to unlock the basis for ES cells' seemingly unlimited potential, they also suggest ways to understand why ordinary cells are so limited in their abilities to repair or replace damaged cells.

Studies indicate stem cells are flexible enough to become any cell in the body

Two studies in the April 21, 2006 Cell report new details of the "genetic program" that affords embryonic stem cells the flexibility to give rise to any cell type in the body. Both groups identified mechanisms by which the embryonic stem cells of mice or humans keep from going down any one particular developmental path--that of muscle or nervous tissue, for example--while remaining "poised for activation."

Enhancing the function of the protein SOCS3 could be a more effective way to regulate cell responses

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.
