Our research program seeks to dissect the complex dynamics of host-virus interactions with a particular focus on the development and function of adaptive immune responses. Since it is still beyond the reach of even the most sophisticated in vitro methodology to simulate the complex interplay of physical, cellular, biochemical, and other factors that influence cell behavior in microvessels and interstitial tissues, we make use of intravital microscopy. This technique is complemented by more traditional molecular, cellular and histological approaches, thus characterizing host-virus interactions at the molecular-, single cell- and whole animal-level.
Ongoing projects in the lab include:
1) To characterize how viruses are handled within draining lymph nodes upon peripheral inoculation and how antiviral immune responses are generated.
2) To dissect liver immunopathology by intravital microscopy.
3) To discover and characterize novel adjuvants for adaptive immune responses.

Project Title:
IN VIVO DYNAMICS OF ANTIBODY RESPONSES TO LYMPH-BORNE VIRUSES
Objective. Our objective is to elucidate how neutralizing antibody (nAb) responses against live lymph-borne viruses are generated in vivo within lymph nodes (LNs). To this end we will make use of state-of-the-art imaging technology (i.e. multiphoton intravital microscopy [MP-IVM]), fluorescent replication-competent viruses and dedicated mouse models.
Background/Rationale. nAbs are critical for virus control, prevention of re-infection and protection conferred by available vaccines. Thanks to the recent advent of MP-IVM, several cellular and molecular events by which LNs orchestrate the generation of humoral immune responses have been clarified. As none of these studies employed live viruses, further work is required to extend these results to a more relevant natural setting. Also, the mechanisms by which acutely cytopathic viruses (e.g. polioviruses and rabies virus in humans and vesicular stomatitis virus [VSV] in mice) induce early high affinity nAb responses while non-cytopathic viruses (e.g. HBV or HCV in humans and lymphocytic choriomeningitis virus [LCMV] in mice) fail to do so remain poorly understood. Our rationale is based on the notion that, by bringing together unique reagents and advanced technology, we can - at last - address these issues experimentally.
Description of the project. The spatial and temporal constraints whereby virus-specific naïve B cells encounter viral antigen, interact with different LN cells and differentiate into plasma cells will be dynamically dissected in the various LN sub-compartments of mice infected with live lymph-borne cytopathic (VSV) and non-cytopathic (LCMV) viruses.
Anticipated output. We will provide the first complete in vivo imaging survey of virus-specific B cell activation, from the first minutes of viral entry into the LN to the generation of high affinity nAb-secreting cells. We will also identify virus-induced mechanisms interfering with nAb responses. This new knowledge will provide much-needed insight into aspects of viral immunity that may lead to novel rational vaccine strategies aimed at inducing rapid and long-lived humoral immune responses.
