Hunter Laboratory

Dr. Christopher Hunter's research team has been working on various aspects of basic parasitology since 198Hunter Laboratory, Penn Vet4.

For ​nearly 25 years, Dr. Hunter's team has focused on understanding how the immune response to Toxoplasma gondii is regulated to allow the development of protective immunity as well as to limit T cell mediated pathology in multiple sites including the gut and brain.

​Dr. Hunter has been working on various aspects of basic parasitology since 1984 and for the last 25 years there has been a focus on understanding how the protective immune response to Toxoplasma gondii develops and how this relates to other parasitic infections.

The Hunter Laboratory team has focused on the innate events that lead to the development of long term protective immunity mediated by T and B cells. These studies led us to develop expertise in cytokine biology and, while the focus has been in understanding their role in infectious disease, these findings are frequently relevant to cytokine function in autoimmunity and inflammatory processes associated with human disease.

For example, as part of studies to understand how IL-12 family members affect immunity to the T. gondii, we showed that IL-27 was important in limiting the T cell-mediated infection-induced inflammation. We have defined the mechanisms used by IL-27 to influence the immune system and our work has been shown to be relevant to inflammatory processes in multiple experimental systems that includes other infections as well as models of auto-immune inflammation, asthma and cancer.

Since toxoplasma causes a chronic infection in the brain there has been a long-term interest in the neuropathogenesis of infectious diseases and how lymphocytes access and operate in this immune privileged site.

In this laboratory we have developed all of the skills required for the routine analysis of multiple innate immune parameters and to quantify DC, macrophage, NK, T and B cell responses to infection.

We are also able to utilize different combinations of transgenic parasites (replication deficient, expressing fluorescent reporters, distinct model antigens OVA and E and the Cre recombinase) and TCR transgenic T cells to provide higher resolution analysis of individual parasite specific CD4 and CD8 T cell populations and apply multi-photon microscopy to image the innate and adaptive response to T. gondii.

As part of this research program Dr. Hunter has supervised more than 50 students from multiple programs that include Penn undergraduates, VMD summer students, graduate students from the Microbiology and Immunology graduate groups as well as combined degree (VMD/PhD and MD/PhD), and PhD candidates and undergraduates from the UK. He has been responsible for the training of 15 post-docs and 26 students (20 PhD, 3 Masters and 3 in training). 

Almost all of these individuals are still in science with trainees in faculty positions at the University of Washington, UPenn, UVA, Columbia, Yale, UMass, UC Riverside, University of Arkansas and six in faculty positions in Canada, Brazil, Japan and Europe, with several in industry (Pfizer, Medimmune), Science policy at Stanford and a Program Advisor to the Malaria Vaccine Initiative.
