Microbial virulence often relies on secreted effectors that modulate host signal transduction, the revelation of the functional mechanisms of pathogen effectors not only leads to a better understanding of microbial virulence strategies but also has the potential to impact human health through novel treatment strategies. Over the past decades, extensive studies of viral and bacterial virulence have immensely expanded our knowledge and understanding of host-pathogen interaction. However, viruses and bacteria are only two classes of microbes that can cause disease, and surprisingly little is known about how eukaryotic pathogens manipulate their hosts. In our lab, we use Toxoplasma gondii as a model organism to study the sophisticated mechanisms this pervasive human eukaryotic pathogen uses to modulate the host immune system.
