  Inorganic polyphosphate (polyP) is a linear polymer composed of three to several hundred orthophosphate units linked by high-energy phosphoanhydride bonds and is found in both prokaryotes and eukaryotes. In Trypanosoma cruzi, the causative agent of Chagas disease, polyP plays important roles in osmoregulation and persistence within host tissues and is synthesized by a polyP polymerase …

  The endoplasmic reticulum (ER) maintains an oxidative environment that facilitates the formation of disulfide bonds, a critical process for proper protein folding. Protein disulfide isomerases (PDIs) are ER-resident enzymes that facilitate the formation, breakage, and rearrangement of disulfide bonds between cysteine residues, thereby stabilizing protein structures. Although PDIs are functionally diverse, they all contain …

  Malaria, caused by intracellular Plasmodium falciparum parasites, remains a major global health concern. These parasites reside and replicate within a vacuole in host red blood cells. Egress of daughter parasites out of the vacuolar and host membranes is tightly regulated via a complex mechanism. Prior studies have suggested that a cyclic-GMP driven calcium signaling …

  Japanese macaques (Macaca fuscata) are used in biomedical research where frequent, small-volume blood sampling for monitoring the animal’s health may be required. Femoral blood collected under anesthesia is the standard for obtaining CBC analyses from nonhuman primates to assess their health. However, anesthetizing animals to obtain these collections may not be ideal due to …
