SLC36A2 and infection: Our future research will determine the secretion pathway(s) for Pat1 and Pat2 from the bacterial cytoplasm, mechanism of translocation into the host cytoplasm during intracellular growth, host subcellular localization and molecular targets, mechanism of activation for PLA activity, and the overall roles of these patatins in the R. typhi intracellular life cycle, especially regarding the early stage of infection including phagosomal escape and host cell lysis.
