Cover photograph (Copyright © 2008, American Society for Microbiology. All Rights Reserved.): Intracellular cluster of Toxoplasma gondii nestled against the host cell nucleus (stained blue with 4′,6-diamidino-2-phenylindole). Individual parasites are outlined by the surface protein SAG1 (shown in red). Cytoplasmic green fluorescent protein (shown in green) overlaps the parasite nucleus, resulting in brighter central staining within each parasite. Our study demonstrates that the actin-like protein 1 (ALP1) in T. gondii is diffusely distributed in nondividing cells but is recruited to nascent daughter cells and is implicated in the unique form of cell division used by apicomplexan parasites.
