New model will open immune cell’s secrets

Five decades after the discovery of a rare but potentially pivotal immune cell, scientists at Washington University School of Medicine in St. Louis have found a way to eliminate it in mice. The finding, which appears in the journal Immunity, will enable more detailed investigations of the important roles the plasmacytoid dendritic cell (pDC) plays in fighting viruses and causing autoimmune diseases like psoriasis and lupus.

Study finds poorer outcomes for African-Americans with arthritis

Arthritis can hit harder in African- Americans.A pilot study comparing the results of treatment for rheumatoid arthritis in African-Americans and Caucasians has revealed that African-Americans are more likely to suffer pain and disability from the disorder. Researchers at the School of Medicine found that both disease activity and the resulting disabilities were worse in African-Americans. Further analysis showed this was linked primarily to socio-economic status rather than race.

Researchers at Washington University School of Medicine in St. Louis studied a group of 33 African-Americans and 67 Caucasians and found that both disease activity and the resulting disabilities were worse in African-Americans.

‘Leash’ protein may help keep B cells from attacking body tissue

B cellsScientists at the School of Medicine have identified a protein that can reduce the chances immune B cells will erroneously attack the body’s own tissues, causing autoimmune disorders like lupus, allergies, arthritis and diabetes. The protein is the first of its kind to be identified in B cells and could provide scientists with a new target for treating such conditions.
