Research Topics:
Our lab is focused on understanding the interactions between bacterial pathogens and the mammalian innate immune system. Innate immune cells, such as macrophages, express receptors that recognize conserved molecules of microbial origin, leading to host immune responses. Using specific recognition of microbial ligands, macrophages can discriminate between viruses and bacteria, extracellular and intracellular microorganisms and live or dead microorganism. The information integrated from the different immune receptors is crucial for the development of proper innate and acquired immune responses. Ironically, while macrophages are important effector cells of the immune system they are permissive hosts for intracellular pathogens, such as Listeria monocytogenes, and how pathogenic bacteria activate and/or manipulate host immune responses is central to the understanding of host-pathogen interactions. In our lab we are focusing on the intracellular bacterial pathogen, L. monocytogenes. L. monocytogenes enters host cells through passive uptake by phagocytosis or by active invasion of non-phagocytic cells. Upon entry into the host cytosol, L. monocytogenes activates a host transcriptional response that can be monitored by the robust expression and synthesis of the cytokine Interferon-b (IFN-b) leading to a Type I interferon response. In attempt to find L. monocytogenes genes that are involved in activation of Interferon-b response in macrophages, we performed an unbiased genetic screen of a L. monocytogenes transposon library for mutants that induced an enhanced or diminished Interferon-b response upon infection of macrophages. Interestingly, in this screen we found 3 independent bacterial multi-drug resistance (MDR) transporter systems, from the major facilitator super family that controlled the magnitude of the Interferon-b response. Bacterial MDRs are associated with resistance to antibiotics and other toxic compounds. We are interested in studying the mechanism by which these bacterial MDR transporters (and other bacterial mechanisms) modulate innate immune responses.
