Furthermore, an anti-IL4Rα/anti-IL5 bispecific antibody decreased the number of recruited lymphocytes and eosinophils during asthmatic reactions in mice more effectively than when either antibody was administered alone or concurrently, demonstrating the ability of IL4R bispecific antibodies to be effective in alleviating symptoms of asthma (54). The gene discussed is IL5; the disease is asthma.
