Inflammation: From Mummies to Melanoma

March 21, 2013 1:46 pm | by Cynthia Fox | Articles | Comments

Inflammation is stirring up headlines again. Anti-inflammatory aspirin prevented thousands more cancers. The anti-inflammatory “miracle molecule” resveratrol came back. Psychologists report inflammation is stoked by even minor tensions. And archaeologists say all this knowledge is long overdue, as even Egyptian mummies have clogged arteries. We have been plagued by inflammation since the time of the Pharaohs.

White Blood Cells Can Control Red Blood Cell Levels

March 17, 2013 3:05 pm | by Einstein | News | Comments

Researchers at Albert Einstein College of Medicine of Yeshiva University and the Icahn School of Medicine at Mount Sinai have found that macrophages – white blood cells that play a key role in the immune response– also help to both produce and eliminate the body’s red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance. The study, conducted in mice, is published today in the online edition of the journal Nature Medicine.
