Th2/1-hybrid cells stably co-expressing the lineage-specifying transcription factors and cytokines of Th2 (GATA-3, IL-4) and Th1 cells (T-bet, IFN-g) are induced in experimental helminth infections (Peine et al. PLOS Biology, 2013). In cooperation with Dr. S. Babu (NIH Research Centre, Chennai, India) we analysed blood cells from patients infected with the threadworm Strongyloides stercoralis. Worm-infected patients show significantly increased numbers of GATA-3+ Th2 cells as well as GATA-3+T-bet+ co-expressing cells (figure). IL-4+IFN-g+ Th2/1-hybrid cells are detectable, which, compared to murine Th2/1 hybrid cells, express very high amounts of IFN-g and low levels of GATA-3 (Bock et al. Frontiers CIM, 2017)
