SOAT1 and Salmonella Infections: We also presented a comprehensive picture of differing transcriptional responses in MEP, M1 and M2 macrophages to Salmonella infection, identified likely mechanisms for differing resistance to the pathogen, and provided evidence that JAK-STAT signaling is mechanistically important for the response of M1 macrophages to Salmonella infection, but not for M2 or for MEP macrophages at the 4 hr time point.
