Malaria Host Pathogen Interaction Center Experiment 30 - Pilot experiment for Macaca mulatta infected with Plasmodium knowlesi Malayan strain sporozoites to produce and integrate measures of acute primary infection. (GSE123495)
This project is part of the Malaria Host-Pathogen Interaction Center (MaHPIC) - a transdisciplinary malaria systems biology research program initially supported by an NIH/NIAID contract (# HHSN272201200031C, 2012-2017; see http://www.systemsbiology.emory.edu). The MaHPIC has continued with support from the Defense Advanced Research Project Agency (DARPA) and others. The MaHPIC generates many data types (e.g., clinical, hematological, parasitological, metabolomics, functional genomics, lipidomics, proteomics, immune response, telemetry) and mathematical models, to iteratively test and develop hypotheses related to the complex host-parasite dynamics in the course of malaria in non-human primates (NHPs), and metabolomics data via collaborations with investigators conducting clinical studies in malaria endemic countries, with the overarching goal of better understanding human disease, pathogenesis, and immunity. Curation and maintenance of all data and metadata are the responsibility of the MaHPIC. Telemetry devices (DSI, model L11) with blood pressure sensors and electrocardiogram (ECG) leads were surgically implanted in two malaria-naive male rhesus macaques (Macaca mulatta), approximately three years of age. After a resting period of two weeks, physiological data that include activity, temperature, ECG, and blood pressure were continuously collected. Two weeks after activation of the telemetry implant, the macaques were inoculated intravenously with cryopreserved P. knowlesi Malayan strain salivary gland sporozoites, obtained from Anopheles dirus infected with parasites from the Pk1A+ clone.  The P. knowlesi sporozoites were produced, isolated and cryopreserved at the Centers for Disease Control and Prevention. After inoculation, the macaques were profiled for clinical, hematological, parasitological, immunological, functional genomic, lipidomic, proteomic, metabolomic, telemetric and histopathological measurements. The experiment was designed for pathology studies, with terminal necropsies on days 11 (RKy15) or 19 (Red16). The anti-malarial drug artemether was subcuratively administered selectively to one subject (REd16) during the primary parasitemia to suppress clinical complications. Capillary blood samples were collected daily for the measurement of complete blood counts, reticulocytes, and parasitemias. Capillary blood samples were collected every other day to obtain plasma for metabolomic analysis. Venous blood and bone marrow samples were collected at five timepoints for functional genomic, proteomic, lipidomic, and immunological analyses. Physiological data were continuously captured via telemetry. Within the MaHPIC, this project is known as 'Experiment 30'. This dataset was produced by Steven E Bosinger, Nirav Patel, and Gregory K Tharp at Emory University.

The experimental design and protocols for this study were approved by the Emory University Institutional Animal Care and Use Committee (IACUC) and the MRMC Office of Research Protection Animal Care and Use Review Office (ACURO).
