IL5 and infection: Irrespective of the presence of chronic HDM‐driven inflammation, we found that during influenza virus infection ILC2s are induced in the BALF with remarkable kinetics: numbers of ILC2s peak at day 4–7 but substantial IL‐5 and IL‐13 cytokine production capacity was only detected later during infection at around day 10–11 in the resolution phase of influenza virus infection when virus particles had been eradicated and the type 1 immune response was reaching its conclusion.
