The Smith Lab are interested in host genetic diversity, bacterial variation, and how these host-pathogen genetic interactions drive tuberculosis disease states.
Systems Genetics of Tuberculosis: We leverage host diversity in mice and macrophages from wild-derived mouse strains and diverse mouse panels, including the Collaborative Cross and BXD mammalian resources. In parallel, we define the bacterial genetic requirements for growth and adaptation across these diverse host environments through new mycobacterial genetic approaches, including saturated libraries of transposon mutants (TnSeq), CRISPRi and knockouts generated through ORBIT (“oligonucleotide-mediated recombineering followed by Bxb1 integrase targeting”). These combined host and bacterial genome-wide approaches allows the interrogation of each host-pathogen interaction underlying TB.

Leveraging the Collaborative Cross mouse panel we have identified new models of distinct TB disease states and protective immunity. Check out how we identified a causal host variant here.
We leverage this dual host-pathogen system to understand how vaccines alter disease outcome in diverse hosts. Read about how host genetic background underlies BCG vaccine efficacy here.
