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.

A team of Swiss researchers found that when a hormone in the brain, erythropoietin (Epo), was elevated in mice, they were more motivated to exercise. In addition, the form of erythropoietin used in these experiments did not elevate red blood cell counts. Such a treatment has obvious benefits for a wide range of health problems ranging from Alzheimer's to obesity, including mental health disorders for which increased physical activity is known to improve symptoms.

UCLA stem-cell researchers have identified a certain type of cell and a signaling pathway in the placental niche that play a key role in stopping blood stem cells from differentiating into mature blood cells in the placenta. Preventing this premature differentiation is critical to ensuring a proper blood supply for an individual's lifetime.

Erythropoietin or EPO might be considered a "performance enhancing" substance for athletes, but new research published online in The FASEB Journal shows that these enhancements come at a high cost--increased risk of vascular problems in the brain. According to the study, short- or long-term use of EPO raises blood pressure by constricting arteries, which reduces the flow of blood to the brain. This finding also contradicts earlier evidence suggesting that EPO may be a viable early treatment for stroke victims.
