New approach to platelet replacement therapy for thrombocytopenia

Platelets are cells in the blood that have a key role in stopping bleeding. Thrombocytopenia is the medical term used to describe the presence of abnormally low numbers of platelets in the blood. Platelet transfusion is used to treat several causes of thrombocytopenia, but there is a shortage of donors. Mortimer Poncz and colleagues, at Children's Hospital of Philadelphia, working with mice, have now identified a potential new approach to platelet replacement therapy that circumvents the problem of donor shortage.

Viral microRNA allows EBV to hide within cells and evade immune system

While most commonly associated with mononucleosis, Epstein-Barr virus (EBV) has been linked to many diseases that affect people long after the initial infection takes place, including some forms of cancer. In the current issue of the Journal of Biological Chemistry, scientists at The Wistar Institute describe how viral microRNA - small segments of RNA that suppress the effects of gene activity - allows EBV to hide within cells and evade the immune system.

La Jolla Institute scientist wins Malpighi Medal for pioneering work in heart disease

Klaus Ley, M.D, a scientist at the La Jolla Institute for Allergy & Immunology, was recently awarded the prestigious Malpighi Medal at the World Congress for Microcirculation in Paris, France. A lifetime achievement award presented by the European Society for Microcirculation, Dr. Ley received the honor in recognition of his pioneering endeavors in vascular immunology, a scientific discipline that he helped to pioneer, which looks at novel immune-based approaches to combating heart disease. He is only the 17th recipient of the biennial award worldwide.

Examining genetic material of egg cells may inform about embryos health

Fertility procedures such as in vitro fertilization (IVF) require a couple and the doctor to place the risky bet that the multiple eggs they choose to fertilize will produce an embryo that will thrive in the uterus. Researchers cannot biopsy eggs directly because that would destroy them, but a new discovery by professors at Brown University and Women & Infants Hospital could lead to new insights about how eggs develop and ultimately inform judgments about how the embryos they produce will fare. The idea is to examine the genetic material the egg cells discarded when they were first forming, to see which genes they were expressing.
