Task: Answer Verification
Input (English): Question: Is expression of IL-4 receptor alpha on smooth muscle cells necessary for development of experimental allergic asthma?
Answer: The impairment of IL-4Ralpha on smooth muscle cells had no effect on major etiologic markers of allergic asthma. These findings suggest that IL-4Ralpha responsiveness in airway smooth muscle cells during the early phase of allergic asthma is not, as suggested, necessary for the outcome of the disease.
Output (English): no
