The Department of Production Animal Health in the Faculty of Veterinary Medicine at the University of Calgary is accepting applications for a Postdoctoral Scholar in Vaccinology and Single Cell Transcriptomics.
Area: Vaccinology and Single Cell Transcriptomics
Duration: 2 years
Start date: Fall 2021
Salary: $50,000 $CAD per year plus Plan C health benefits
Project Title:
Single cell transcriptomics of Mycobacterium avium subsp. paratuberculosis infections and vaccinations in macrophage, mouse and calf models
Job Description:
Johne’s disease (JD) is a chronic intestinal infectious disease causing huge economic impact on the dairy industry. Although efforts have been made to manage this disease, there are still limited tools to control it efficiently. Current control measures are held up by low sensitivity and low specificity of available diagnostic tests and failure of existing vaccines to prevent infection. Available vaccines do not provide enough protection to the host, nor do they prevent the spread of Mycobacterium avium subsp. paratuberculosis (MAP), the causative agent of Johne’s disease. Although genetic manipulation of MAP has proven to be difficult, we have developed live attenuated vaccine strains by knocking out essential genes. Essential genes for MAP growth and replication in the natural host’s body were previously identified in our lab by Tn-seq. Two top essential genes which play a role in MAP energy metabolism and metal uptake in host cell were chosen for further studies. Site directed mutagenesis was used to knock-out these genes which normally help MAP to persist in host body. These two single mutant strains were tested in a calf infection model to measure MAP colonization in infected tissue, quantity of MAP in feces, PBMCs gene expression, peripheral immune cell types and bacterial viability assay.
It is known that MAP subverts the host immune system by using macrophages as its primary reservoir. But the mechanisms how MAP vaccines provide protection against natural infections are not yet fully understood. We aim to use a new emerging technology, single cell transcriptomics, to study the effect of infection with WT and vaccine strains on downstream transcriptomics of genes related to specific biological processes including inflammatory processes, tolerance, putative epigenetic modifiers, and lipid homeostasis.
Our vaccine and WT strains will be further tested in bovine macrophage, mouse infection model, and calf infection models. We are interested in intestinal tissue and lymph nodes single cell transcriptomics to help us characterize the genes involved in JD pathogenesis and protection pathways cells isolated from the site of infection.
