We appreciate the thoughtful comments of Vicetti Miguel et al. One of the main purposes of writing a review is to generate a discussion, and optimal times for reviews are moments where long held paradigms begin to look a little shaky. We do not disagree with the commentators’ critique of the existing literature in the context of the existing Th1,-2,-17... framework, except that there are newer T cell lineage data that show the following.(i) Interleukin-13 (IL-13) is not uniquely a Th2 cytokine, and Gata3 is not unique to Th2 cells. In the published literature, CD8 T cells from patients with systemic sclerosis (SSc) and tuberculosis make both gamma interferon (IFN-) and IL-13 and express Gata3. On the basis of incomplete information, in SSc, the relevant Gata3 partner transcription factor is likely T-bet (1), in tuberculosis, perhaps Eomes (2). In any case, the mutual exclusivity rules for cytokine polarization do not appear inviolate in vivo. Table 1 shows gene expression microarray data for four multifunctional Chlamydia-specific Th1 clones (uvmo-2, uvmo-3, uvmo-4, and spl4-10) that we obtained in a study published in 2012 (3). These data were not discussed in that paper but are publically available in the Gene Expression Omnibus database under accession number GSE32128.These Chlamydia-specific CD4 T cell clones made abundant IFN-, had high mRNA signals for T-bet (Tbx21) and Gata3, and were essentially negative for RORT (Rorc) and Ahr. There was a low positive Eomes mRNA signal in one of the four clones (116 arbitrary units). We know specifically that 4uvmo-3 has significant Gata3 mRNA, produces large amounts of IFN-, and does not produce IL-5 or IL-13 (we did not specifically check for IL-4). We have additional unpublished data addressing these issues consistent with the cytokine plasticity discussed above.(ii) The presence of circulating CD4 T cells that make IL-4 does not equal protection. We did not look at IL-4 responses during our study of commercial sex workers, but we did look at IL-5 (the Th2 cytokine that promotes eosinophilia), and it was not associated with resistance to reinfection.
