Protein helps parasite survive in host cells

Researchers at Washington University School of Medicine in St. Louis have learned why changes in a single gene, ROP18, contribute substantially to dangerous forms of the parasite Toxoplasma gondii. The answer has likely moved science a step closer to new ways to beat Toxoplasma and many other parasites.

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.
