New model reveals how immune system functions under conditions of neutropenia

Cancer chemotherapy can be a life-saver, but it is fraught with severe side effects, among them an increased risk of infection. Until now, the major criterion for assessing this risk has been the blood cell count: if the number of white blood cells falls below a critical threshold, the risk of infection is thought to be high.

Scripps scientists discover new antibody-discovery technique

Scientists at The Scripps Research Institute have found a new technique that should greatly speed the discovery of medically and scientifically useful antibodies, immune system proteins that detect and destroy invaders such as bacteria and viruses. New methods to discover antibodies are important because antibodies make up the fastest growing sector of human therapeutics; it is estimated that by 2014 the top-three selling drugs worldwide will be antibodies.

Molecular insight into oxygen sensing mechanism

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's.

Blocking GSK3b enzyme can prevent bacterial-induced periodontal bone loss

A University of Louisville scientist has found a way to prevent inflammation and bone loss surrounding the teeth by blocking a natural signaling pathway of the enzyme GSK3b, which plays an important role in directing the immune response.

'Deep sleep' intimately involved in complex control of pubertal onset

Slow-wave sleep, or 'deep sleep', is intimately involved in the complex control of the onset of puberty, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).

Genes predict the brain's reaction to smoking

Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. A study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows that people with genetically fast nicotine metabolism have a significantly greater brain response to smoking cues than those with slow nicotine metabolism.

Serum-concentration of antioxidants is significantly lower in patients with mild dementia

Forgetfulness, lack of orientation, cognitive decline… about 700, 000 Germans suffer from Alzheimer's disease (AD). Now researchers from the University of Ulm, among them the Epidemiologist Professor Gabriele Nagel and the Neurologist Professor Christine von Arnim, have discovered that the serum-concentration of the antioxidants vitamin C and beta-carotene are significantly lower in patients with mild dementia than in control persons.

Berkeley lab researchers link possible new oncogene with resistance to cancer drugs

A gene that may possibly belong to an entire new family of oncogenes has been linked by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) to the resistance of breast cancer to a well-regarded and widely used cancer therapy.

Karolinska Institutet professor receives Fernström Foundation Nordic Prize for obesity research

This year's Fernström Foundation Nordic Prize, worth SEK 1 million, goes to Professor Peter Arner from Karolinska Institutet, Sweden, who conducts research on fat. His team was the first to show that fat cells are formed throughout one's lifetime, not just in childhood.

BRI scientists receive two major grant awards for research into autoimmunity prevention

Benaroya Research Institute at Virginia Mason (BRI) recently received two major grant awards to explore how to regulate the immune system, as part of a nationwide collaborative program to prevent autoimmune diseases.

Mount Sinai scientists identify cancer’s Achilles heel

Scientists at Mount Sinai School of Medicine have discovered a subpopulation of cells that display cancer stem cell properties and resistance to chemotherapy, and participate in tumor progression. This breakthrough could lead to the development of new tests for early cancer diagnosis, prognostic tests, and innovative therapeutic strategies, as reported in Cancer Cell.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

First demonstration of newly developed dual humanized FRGTM KO system against malaria

A novel human liver-chimeric mouse model developed at Oregon Health & Science University and Yecuris Corporation has made possible a research breakthrough at Seattle Biomedical Research Institute that will greatly accelerate studies of the most lethal forms of human malaria.

KRAS gene mutation recruits second player to trigger pancreatic cancer

More than a cancer-causing gene is needed to trigger pancreatic cancer, a study led by Mayo Clinic has found. A second factor creates a "perfect storm" that allows tumors to form, the researchers say. The study, published in the Sept. 10 issue of Cancer Cell, overturns the current belief that a mutation in the KRAS oncogene is enough to initiate pancreatic cancer and unrestrained cell growth.

Polysaccharopeptide improves survival in dogs with hemangiosarcoma

Dogs with hemangiosarcoma that were treated with a compound derived from the Coriolus versicolor mushroom had the longest survival times ever reported for dogs with the disease.

U of I microbial engineer synthesizes 2-fucosyllactose to protect babies from pathogens

A University of Illinois microbial engineer has synthesized a sugar in human milk that is thought to protect babies from pathogens. That's important because 2FL, the shorthand scientists use to describe this human milk oligosaccharide (HMO), has not been added to infant formula because HMOs are incredibly expensive.

MicroRNA-145 gene therapy can drastically reduce severity and progression of atherosclerosis

Researchers at St. Michael's Hospital are one step closer to understanding why plaque bursts in coronary arteries and causes heart attacks.
