Double-Duty Protein Triggers Parasite Entry and Replication (2 of 2)

Caption

Intracellular Toxoplasma gondii parasites are replicating inside a parasitophorous vacuole in human fibroblasts. Five vacuoles are visible, individual parasites are labeled in green, and a protein deposited into the parasitophorous vacuole by the parasite is labeled in red. This image relates to an article that appeared in the Dec. 23, 2010, issue of Science Express, published by AAAS. The study, by Dr. J.M. Santos at University of Geneva in Geneva, Switzerland, and colleagues was titled, “Intramembrane Cleavage of AMA1 Triggers Toxoplasma to Switch from an Invasive to a Replicative Mode."
