Antibodies reverse type 1 diabetes in new immunotherapy animal study

Antibodies reverse type 1 diabetes in new immunotherapy animal study

ScienceDaily (July 6, 2012) — Scientists at the University of North Carolina School of Medicine have used injections of antibodies to rapidly reverse the onset of Type I diabetes in mice genetically bred to develop the disease. Moreover, just two injections maintained disease remission indefinitely without harming the immune system. Continue reading

Pigs in southern China infected with avian flu

Pigs in southern China infected with avian flu

Dec. 19, 2012 — Researchers report for the first time the seroprevalence of three strains of avian influenza viruses in pigs in southern China, but not the H5N1 avian influenza virus. Their research, published online ahead of print in the Journal of Clinical Microbiology , has implications for efforts to protect the public health from pandemics. Continue reading

Host cholesterol secretion likely to influence gut microbiota

Host cholesterol secretion likely to influence gut microbiota

Dec. 18, 2012 — For more than half a century, researchers have known that the bacteria that colonize the gastrointestinal tract of mammals influence their host’s cholesterol metabolism. Now, Jens Walter and colleagues of the University of Nebraska show that changes in cholesterol metabolism induced by diet can alter the gut flora. Continue reading

Drug used to treat HIV might defuse deadly staph infections

Drug used to treat HIV might defuse deadly staph infections

Dec. 14, 2012 — A new study by NYU School of Medicine researchers suggests that an existing HIV drug called maraviroc could be a potential therapy for Staphylococcus aureus , a notorious and deadly pathogen linked to hundreds of thousands of hospitalizations each year. Their study is published online this week in Nature . Continue reading

Drug that may help fight Duchenne muscular dystrophy discovered

Drug that may help fight Duchenne muscular dystrophy discovered

Dec. 12, 2012 — Drugs are currently being tested that show promise in treating patients with Duchenne muscular dystrophy (DMD), an inherited disease that affects about one in 3,600 boys and results in muscle degeneration and, eventually, death. Now, scientists at UCLA have found a drug, already approved by the U.S Continue reading

Predator-producing bacteria may be battling in human intestines

Dec. 11, 2012 — Unique viruses called bacteriophages may play an important role in competition among bacterial strains, influencing the overall ecosystem of the human intestine, scientists at The University of Texas at Arlington and UT Southwestern Medical Center say. A team led by Lora V Continue reading

New coronavirus has many potential hosts, could pass from animals to humans repeatedly

Dec. 11, 2012 — The SARS epidemic of 2002-2003 was short-lived, but a novel type of human coronavirus that is alarming public health authorities can infect cells from humans and bats alike, a fact that could make the animals a continuing source of infection, according to a study to be published in in mBio® , the online open-access journal of the American Society for Microbiology, on December 11.

Bugs without borders: Researchers track the emergence and global spread of healthcare associated Clostridium difficile

Bugs without borders: Researchers track the emergence and global spread of healthcare associated Clostridium difficile

Dec. 9, 2012 — Researchers show that the global epidemic of Clostridium difficile 027/NAP1/BI in the early to mid-2000s was caused by the spread of two different but highly related strains of the bacterium rather than one as was previously thought. The spread and persistence of both epidemics were driven by the acquisition of resistance to a frontline antibiotic. Continue reading

Scientists target DNA repair to eradicate leukemia stem cells

Scientists target DNA repair to eradicate leukemia stem cells

Dec. 9, 2012 — Despite treatment with imatinib, a successful drug that targets chronic myeloid leukemia (CML), a deadly type of cancer, some patients may continue to be at risk for relapse because a tiny pool of stem cells is resistant to treatment and may even accumulate additional genetic aberrations, eventually leading to disease progression and relapse. These leukemia stem cells are full of genetic errors, loaded with potentially lethal breaks in DNA, and are in a state of constant self-repair Continue reading
