To initiate a protective response to an infection, mammals must detect microbial pathogens directly or detect the damage that they cause.  The immune sensor that we are studying detects the presence of microbial pathogens by monitoring the alterations in cellular metabolism caused by intracellular bacteria.  This sensor, called NLRP1B, becomes activated in cells undergoing energy stress. Activated NLRP1B forms an inflammasome complex that processes pro-caspase-1 to generate an immune response.  We are interested in understanding the molecular mechanisms behind these events.
