IL9 and infection: Levels of six other chemokines and cytokines (IL-5, IL-1α, IL-3, G-CSF, IL-9, and eotaxin) were modestly increased or not increased with infection over time, but were reduced in basoIL-18R (−) mice relative to basoIL-18R (+) mice at 4 d PI (IL-5) or at 10 d PI (IL-1α, IL-3, G-CSF, IL-9, eotaxin; Fig. 5E-J).
