Our data showed the Lineage-cells from both mugwort-allergic asthma group and HDM-allergic asthma group could produce significant amounts of IL-5 and IL-13 after the stimulation with IL-33 when compared to IL-2 alone (all P < 0.05, respectively), or medium alone (all P < 0.05, respectively). Here, IL2 is linked to allergic asthma.
