Th single cell RNA-Seq

Th2 cells regulate helminth infections, allergic disorders, tumor immunity and pregnancy by secreting various cytokines. It is likely that there are undiscovered Th2-signaling molecules. While steroids are known to be immunoregulators, de novo steroid production from immune cells has not been previously characterised. We demonstrate production of the steroid pregnenolone by Th2 cells in vitro, and in vivo in a helminth infection model. To identify gene-expression identify of these steroidogenic-Th2 cells, we performed single-cell RNA-sequencing.
