Consistent with the results of Th cell subset in mice (Figure S1 and Figure 2), the asthma group displayed higher levels of IL-4, IL-17, IL-6, and TGF-β mRNA expression and lower levels of IFN-γ and IL-10 mRNA in the splenocytes than the normal and PBS groups (Figure 4A). This evidence concerns the gene IL4 and asthma.
