Project description:We performed V(D)J scRNA sequencing to find transcriptional and B cell receptor repertoire differences in the germinal center of the draining lymph node of mice born to mothers chronically infected with Schistosoma mansoni. Cite-seq was used to help identify antigen specific cells.

Project description:Maternal helminth infections are a global public health concern and correlate with altered infant immune responses to some childhood immunizations, but a mechanistic understanding of how maternal helminth infection alters the cellular immune responses of offspring is lacking. Here we establish a model of maternal Schistosoma mansoni infection in dual IL-4 reporter mice. We find that offspring born to mothers infected with S. mansoni have impaired production of IL-4 during homoeostasis, and following immunization with a Tetanus-Diphtheria vaccine. Single-cell RNASeq analysis of immunized offspring identified egg antigen-dependent reductions in B-cell cell cycle and proliferation-related genes.

Project description:Despite strong evidence that prior helminth infection exerts a protective effect against the development of metabolic disease, a major gap exists in understanding the mechanism(s) underlying this protection. We previously found that Schistosoma mansoni infection induces dramatic transcriptional alterations in hepatic macrophage metabolism, and that this correlates with protection from high fat diet (HFD) induced atherosclerosis and glucose intolerance in male ApoE-/- mice. We sought in the present study to determine the broad effects of S. mansoni exposure on the myeloid lineage using the ApoE-/- HFD model. We uncovered that macrophages derived from the bone marrow of S. mansoni infected male mice have dramatically increased oxygen consumption and mitochondrial mass compared to those from uninfected mice. This shift is accompanied by increased glucose shuttling into TCA cycle intermediates and decreased cholesterol esters. When we examined the role of biological sex in schistosome induced modulation. We found that S. mansoni infection does not reliably protect ApoE-/- female mice from HFD induced weight gain or glucose intolerance. The sex-dependent effect of infection extends to myeloid precursors, where the metabolic phenotype of bone marrow derived macrophages from infected females are the opposite of those from infected males. Overall, these data present the first evidence that S. mansoni systemically modulates the myeloid compartment in a sex-dependent manner.

For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/ Schistosomiasis is a severe debilitating illness that represents one of the most important parasitic diseases in tropical areas. It affects over 200 million people across 74 countries. The complete genome sequence of Schistosoma mansoni was published in 2009, but immune response against this parasite is not well characterized. This study is to investigate the overall immune response, antibody and TCR repertoire of immunologically nave mice, mice infected with S.mansoni and mice challenged with a secondary schistosome infection.RNA-seq data will be used to characterise the systemic immune response of mouse to Schistosoma infection, including both whole-transcriptome sequencing for a global picture of the immune response, and sequencing the lymphocyte antigen receptor genes to get a detailed picture of the adaptive immune response.

Project description:Background: The parasitic trematode Schistosoma mansoni is one of the major causative agents of human schistosomiasis, which afflicts 200 million people worldwide. Praziquantel is still the only drug used for schistosomiasis treatment and reduction in drug efficiency has prompting the search for new therapeutic compounds against this disease. Our group has demonstrated that heme crystallization into hemozoin (Hz) within S. mansoni gut is a major heme detoxification route involving lipid droplets in this process and acting as a potential chemotherapeutical target. In the present work, we investigated the effects of the antimalarial quinine (QN) in a murine schistosomiasis model by using a combination of biochemical, cell biology and molecular biology approaches. Methodology/Principal Findings: Treatment of S. mansoni-infected female Swiss mice with daily intraperitoneal injections of QN (75mg/kg/day) from 11th to 17th day after infection decreased not only total, males and females worm burden (46.2 %-51.0 %), eggs production, but also the granulomatous reaction to parasite eggs trapped in the liver. These effects correlated with a significant impairment of Hz production (40%) specifically in S. mansoni females, being parallel to remarkable ultrastructural changes in female worms, particularly in the gut epithelium. Microarray gene expression analysis indicated that QN treatment increased the expression of transcripts related to musculature, protein synthesis and repair mechanisms. Conclusions: The overall significant reduction in several disease burden parameters by QN treatment indicates that interference of Hz formation in S. mansoni is a valid chemotherapeutical target for development of new antischistosomal drugs.
