B-cell substances may play a role in MS progression

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment.

Eltrombopag can raise blood cell levels in some people with severe aplastic anemia

Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies.

Researchers reveal how WBCs move to infection or inflammation in the body

Researchers in the biological sciences department in the Faculty of Science at the University of Calgary have revealed how white blood cells move to infection or inflammation in the body; findings which could help lead to developing drug therapies for immune system disorders.

Study suggests new treatment strategy for heart attacks and strokes

A heart attack doesn't just damage heart muscle tissue by cutting off its blood supply, it also sets off an inflammatory cascade that worsens underlying atherosclerosis, actively increasing the risk for a future heart attack. These findings from a study receiving advance online publication in Nature suggest an important new therapeutic strategy for preventing heart attacks and strokes, both of which are caused when atherosclerotic plaques rupture and block important blood vessels.

Common experience of menopausal symptoms not associated with heart disease risk

The hot flashes and night sweats that most women experience early in menopause are not linked to increased levels of cardiovascular disease risk markers unless the symptoms persist or start many years after menopause begins. These new study results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

Clinical trial to examine effectiveness of combined vaccine and hormone treatment for prostate cancer

Investigators at The Cancer Institute of New Jersey (CINJ) have partnered with the National Cancer Institute (NCI) and launched a clinical trial examining the effectiveness of a combined vaccine and hormone treatment for prostate cancer that is resistant to hormone therapy and not visible on imaging tests such as a CT scan and a bone scan.

New optical microscope sees individual blood cells as they flow inside the body

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as traditional blood test in real-time, simply by shining a light through the skin.

Study uncovers mechanism by which Notch pathway could contribute to RA

A new study led by researchers at Hospital for Special Surgery identifies the mechanism by which a cell signaling pathway contributes to the development of rheumatoid arthritis (RA). In addition, the study provides evidence that drugs under development for diseases such as cancer could potentially be used to treat RA.
