Task: Answer Verification
Input (English): Question: Are sensory neuropeptides directly involved in bronchial hyperresponsiveness induced by interleukin-8 in guinea-pigs in vivo?
Answer: We conclude that repeated intranasal administration of IL-8 causes bronchial hyperresponsiveness (BHR) and that neuropeptides such as neurokinin A and substance P do not directly contribute to the development of BHR induced by IL-8.
Output (English): no
