Explanation:
Lactation during breastfeeding is regulated by positive feedback. As the baby starts sucking, the stimulus (suckling) is sensed by the receptors present in the skin of mammary glands. These signals are carried to the control center, the hypothalamus. Signals are sent to the posterior pituitary to release oxytocin hormone in the blood. The hormone reaches its target organ, mammary glands and stimulates the ejection of milk. Therefore, milk ejection is stimulated by hormone oxytocin in response to suckling.
Since the stimulus, suckling serves to intensify the milk ejection, the regulation is positive feedback. Here, change in a condition triggers a response to intensify the change, not to counteract it.
Interleukin-5 (IL-5). IL-5 is responsible for the recruitment and maturation of eosinophil. Eosinophils on the other hand are majorly involved in the inflammatory response in asthma- characterised by narrowing of the airways. Mepolizumab and reslizumab are, therefore, anti-IL-5
