In terms of expression of the memory ILC2 marker Il17rb, even though it seems that naïve ILC2s express slightly higher amount of Il17rb than ta-ILC2s (Fig. 4d), there is no significant expression change (log2FC < 0.01) in the overall ILC2 populations regardless of tumour exposure or ex vivo stimulation likely due to the small cluster size of the memory ILC2 subtype (Table 1). The gene discussed is IL17RB; the disease is neoplasm.
