Pericytes regulate blood-brain barrier

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

Research team creates first 'lipidome' of human plasma

Human blood is famously fraught with fats; now researchers have a specific idea of just how numerous and diverse these lipids actually are. A national research team, led by scientists at the University of California, San Diego School of Medicine, has created the first "lipidome" of human plasma, identifying and quantifying almost 600 distinct fat species circulating in human blood.

New combination technique improves study of protein characterization

Using a combination of high-powered computers and advanced experimental magnetic resonance data, a Florida State University biophysical chemist has developed techniques that improve the way scientists can study and predict the structure and dynamics of proteins found in the human body. His innovations could ultimately shorten the time it takes researchers to develop new, more effective drugs and better understand biomedical processes that underlie a variety of health conditions.

Invasive plants increase risk of tick-borne disease in suburbs as well

"You don't have to go out into the woods anymore," says tick expert Brian F. Allan, PhD, who just completed a postdoctoral appointment at Washington University in St. Louis. "The deer are bringing tick-borne disease to us."

Biologists recommend virtual institute for RNA research

A Europe-wide network of labs focusing on RNA research is needed to make the most of RNA's high potential for treating a wide range of diseases. The recommendation for this virtual research institute comes from a panel of biologists at the European Science Foundation in a report published today, 'RNA World: a new frontier in biomedical research'.

VBI researchers receive grant to study immune responses to gut pathogens

The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, has awarded a $10.6 million grant to researchers at the Virginia Bioinformatics Institute (VBI) and collaborators to determine how the human immune system responds to infection by pathogens of the gut. The funding will be used to apply mathematical modeling to the study of immune responses to gut pathogens.

University of Missouri creates National Botanical Research Center with $7.5M NIH grant

Americans spend $25 billion a year on dietary supplement products such as herbs and other botanicals. While the Nutrition Business Journal forecasts that sales of botanical dietary supplements will increase by about 19 percent over the next five years, scientists still don't know the precise properties that make certain plants helpful or harmful to humans. Now, with a new $7.5 million grant from the National Institutes of Health, University of Missouri researchers have created a National Botanical Research Center to answer these questions.

Scientists identify molecular mechanism of muscle stem cell differentiation

Under normal circumstances, adult stem cells reside in muscle tissue, where they can differentiate into a number of different cell types. After an injury (or even a tough workout), muscles are inflamed as cells and molecules flood the area to control damage and begin repairs. When called upon to replace muscle tissue damaged by injury or genetic disease, some muscle stem cells differentiate, becoming new muscle cells, while others make more stem cells. At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team of scientists led by Pier Lorenzo Puri, M.D., Ph.D., recently uncovered the molecular messengers that translate inflammatory signals into the genetic changes that tell muscle stem cells to differentiate.

SAFC expands fermentation capabilities in Israel facility

SAFC, a member of the Sigma-Aldrich® Group (Nasdaq: SIAL), today announced the completion of its state-of-the-art expansion of its Jerusalem, Israel facility. The additional capacity expands SAFC's contract manufacturing capabilities in large molecule recombinant proteins and small molecule Active Pharmaceutical Ingredients (APIs) through fermentation, including High Potent APIs (HPAPIs) and secondary metabolites.

Natural variation shows promise for increasing provitamin A in cassava roots

The roots of cassava (Manihot esculenta) serve as the primary source of carbohydrates in the diets of people in many arid regions of the world, including more than 250 million people in sub-Saharan Africa. Unfortunately the roots of commercial cassava cultivars are quite low in micronutrients, and micronutrient deficiencies are widespread in these regions.

Researchers find new way to increase number of blood-forming stem cells when grown outside the body

One of the major challenges in stem cell transplants is how to obtain sufficient numbers of these remarkably rare cells to put into patients. To help overcome this issue, research from the Centenary Institute, Royal Prince Alfred Hospital and the University of Sydney has found a way to increase the number of blood-forming stem cells when growing them outside of the body.

Study on immune system activation may help develop new drugs for infections

A new research report in the October 2010 print issue of the Journal of Leukocyte Biology sheds important light on how our immune systems detect invading organisms to be destroyed and removed from our bodies. The information from this research should ultimately help lead to the development of new drugs and treatments that allow health care providers to prevent runaway immune reactions that can have devastating consequences for people.
