Recently, we have shown that fate of a vaccine is determined by the cytokine milieu in the innate immune compartment at the early stage of vaccination. Specifically, 24 h post-delivery, level of innate lymphoid cell type 2 (ILC2)-derived IL-13/IL-13Rα2 are the master regulators of DC and also different ILC subsets responsible for modulating the downstream immune outcomes. Here, we provide step-by-step details how to assess different ILC and DC subsets in lung and muscle following intranasal and intramuscular viral vector vaccination, respectively, using multi-color flow cytometry and confocal microscopy.
