Pathogenesis, therapy and prevention of severe influenza in a nonhuman primate model: We have developed the first reproducible model of severe influenza in macaques by administering highly pathogenic avian influenza virus in the form of small particle aerosols, in collaboration with Doug Reed, PhD, of the Center for Vaccine Research. This work is possible because of the Regional Biocontainment Laboratory, a specialized BSL-3 and ABSL-3 facility. Using this novel and powerful model we are working in three different projects: (1) Defining the innate mechanisms driving severe disease in the lung; (2) Testing novel therapeutic approaches targeting innate immune pathways to prevent severe disease; and (3) Testing the efficacy of universal vaccines and broadly neutralizing antibodies to prevent severe disease.
Dengue virus infection in human skin: Dengue virus is transmitted into skin via the bites of infected mosquitoes, but we do not know how the mosquito interacts with the virus and host to effect transmission and spread within the host. To study this in a relevant translational model we inoculate healthy human skin explants that have been removed from anonymous donors in the course of elective plastic surgery. We are collaborating with a team of vector biologists at the University of Texas Medical Branch to study how infected mosquitoes transmit and spread virus using this model.
SARS-CoV-2 infection and immunology: The lung is the primary target of SARS-CoV-2 in humans, and to study the virus-host interaction in this tissue we have established a model using precision-cut human lung slices from cadavers. We also have collaborative studies with a number of groups to evaluate novel therapies including antibodies for COVID-19.
