Study suggests adverse role for BclI polymorphism in obesity and insulin resistance

A large study in people at risk of diabetes has found a direct association between the presence of a small genetic alteration in a hormone receptor and increased body fat and insulin resistance. The results, to be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston, suggest an adverse role for a previously described genetic variant, the BclI polymorphism.

New type of micromachine can penetrate tissue and overcome cellular barriers

Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed.

SIR/TAC combination more effective in preventing GVHD after allogeneic blood cell transplantation

Researchers at Moffitt Cancer Center have conducted a clinical trial aimed at preventing graft vs. host disease (GVHD) in patients who have received hematopoietic (blood) cell transplants (HCT). The study, comparing the drug tacrolimus (TAC) in combination with either methotrexate (MTX ) or sirolimus (SIR), found that the sirolimus/tacrolimus (SIR/TAC) combination was more effective in preventing grades II-IV acute GVHD and moderate-severe chronic GVHD after allogeneic blood cell transplantation.

Scientists discover new flu-fighting role for IL-15 protein

University of Georgia scientists have discovered a new flu-fighting role for a well-known component of the immune system. Kimberly Klonowski, assistant professor of cellular biology in the UGA Franklin College of Arts and Sciences, and her colleagues found that administering a cell-signaling protein known as IL-15 to mice infected with influenza reduces their peak viral load by nearly three times.

Scientists identify novel mechanism behind bacterial pathogenesis

Scientists have identified a new mechanism of bacterial pathogenesis. The results of the research project, partly funded by the Academy of Finland, have been published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

ESCs and iPSCs demonstrate similar survival and neural differentiation capabilities

Researchers in Japan who evaluated the risks and efficacy of transplanting two varieties of stem cells into mouse cochlea have concluded that both adult-derived induced pluripotent stem (iPS) cells and mouse embryonic stem (ES) cells demonstrate similar survival and neural differentiation capabilities.

Exposure to BBzP during pregnancy can increase risk of eczema in children

Prenatal exposure to a ubiquitous household chemical called butylbenzyl phthalate (BBzP) can increase a child's risk for developing eczema, according to research conducted at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health.

Targeted delivery of therapeutic gene can effectively treat Pompe disease

Gene therapy to replace the protein missing in Pompe disease can be effective if the patient's immune system does not react against the therapy. Targeted delivery of the gene to the liver, instead of throughout the body,suppresses the immune response, improving the therapeutic effect, according to an article published in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc.

FDA approves Baxter's GAMMAGARD LIQUID for multifocal motor neuropathy

Baxter International Inc. today announced that the U.S. Food and Drug Administration (FDA) has approved GAMMAGARD LIQUID 10% [Immune Globulin Infusion (Human)] as a treatment for multifocal motor neuropathy (MMN). This is the first immunoglobulin treatment approved for MMN patients in the United States, and it was approved for use with MMN patients in Europe in 2011.

GMCSF linked with rapid cognitive recovery in patients with cancer

Growth factors shown to cure Alzheimer's disease in a mouse model and administered to cancer patients as part of their treatment regimen were linked to significant improvements in the patients' cognitive function following stem cell transplantation, a preliminary clinical study reports.

Scientists recommend new type of therapeutic approach to dementia

Scientists at Charité - Universitätsmedizin Berlin have succeeded in recommending a new type of therapeutic approach to dementia. The study published in the journal Neurology shows that immune reactions against the body's own nerve cells can be the cause of advanced dementia and an appropriate immune suppressive therapy can develop with significant effectiveness.

Researchers identify new virus alert signal that triggers the human immune system

Researchers from Aarhus University have now located the place in the human body where the earliest virus alert signal triggers the human immune system. They have also discovered a new alarm signal, which is activated at the very first sign of a virus attack.

International conference showcases breadth of research possible with zebrafish

It's clear where the black-and-white striped zebrafish got its name, but less obvious at first glance is what zebrafish has to do with biomedical research. Amazingly, it has biological similarities to humans, which are making this small freshwater fish an increasingly popular model organism for studying vertebrate development, genetics, physiology, and mechanisms of disease.

First study to demonstrate that microbes are specific to their host species

Gut bacteria's key role in immunity is tuned to the host species, researchers have found, suggesting that the superabundant microbes lining our digestive tract evolved with us-a tantalizing clue in the mysterious recent spike in human autoimmune disorders.
