Eosinophilic chemotactic factor', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Eosinophils are characteristically found in inflammatory sites around parasitic infections and as pa of immune reactions mediated by IgE, typically associated with allergies. Their recruitment is driven by adhesion molecules similar to those used by neutrophils, and by specific chemokines (e.g., eotaxin) derived from leukocytes and epithelial cells. Eosinophil granules contain major basic protein, a highly charged cationic protein that is toxic to parasites but also causes epithelial cell necrosis. Hydrolytic enzymes are secreted by lysosomes Robbins 9 th edition page no. 55', 'role': 'assistant'}]
