- 07:48Conclusion
IL-9-expressing T and ILC2 cells are induced during N. brasiliensis infection, yet their characterization has been largely overlooked in the infected intestine due to their low frequency and differential kinetics. This protocol describes the isolation of these cells from different target organs and confirmation of their identity via flow cytometry at different infection stages.
