IL5 and asthma: GSYJ may regulate transcription factors (cJUN/IRF3/NF-κB) to decrease the expression of IL-1β, IL-6, RANTES, and iNOS in macrophages and affect the IL-12, IFN-γ, IL-5, and IL-6 levels in the BALF of mice to relieve asthma symptoms, such as inflammatory cell infiltration, hyperresponsiveness, and increased serum total IgE levels.
