Andrew J. Olive works in the field of host responses to chronic infections. In this mSphere of Influence article, he reflects on how “Tryptophan biosynthesis protects mycobacteria from CD4 T-cell-mediated killing” (Y. J. Zhang, M. C. Reddy, T. R. Ioerger, A. C. Rothchild, et al., Cell 155:1296–1308, 2013, https://doi.org/10.1016/j.cell.2013.10.045) impacted his own work using genetic approaches to dissect the interface between host and pathogen.
