Unlabelled: parasites, the causative agents of malaria, undergo closed mitosis without breakdown of the nuclear envelope. Unlike closed mitosis in yeast, parasites undergo multiple rounds of asynchronous nuclear divisions in a shared cytoplasm. This results in a multinucleated organism prior to the formation of daughter cells within an infected red blood cell.

Here we employ omics-based methods with the closely related chemical analog, GNF179, to search for potential targets. Ranking potential targets derived from chemical genetics and proteomic affinity chromatography methodologies identifies , or Synthetic Enhancement of YOP1, which is predicted to encode an essential dynamin-like GTPase implicated in homotypic fusion of endoplasmic reticulum (ER) membranes.

Parasite proliferation within human red blood cells (RBCs) is associated with the clinical manifestations of the disease. This asexual expansion within human RBCs begins with the invasion of RBCs by P.

Parasite proliferation within human red blood cells (RBC) is associated with the clinical manifestations of the disease. This asexual expansion within human RBCs, begins with the invasion of RBCs by , which is mediated by the secretion of effectors from two specialized club-shaped secretory organelles in merozoite-stage parasites known as rhoptries.
View Article and Find Full Text PDFApicomplexan parasites exhibit tremendous diversity in much of their fundamental cell biology, but study of these organisms using light microscopy is often hindered by their small size. Ultrastructural expansion microscopy (U-ExM) is a microscopy preparation method that physically expands the sample by ~4.5×.
