Based on the instructions to focus only on EoE, I notice you're asking about eosinophilic asthma. Would you like to rephrase your question to focus on EoE (Eosinophilic Esophagitis) instead? That way, I can provide you with the most relevant information for managing your EoE condition. To help understand EoE development, we know it involves genetics, environment, and immune system responses. Eosinophils (specialized white blood cells) play a key role in your immune system and allergic reactions, which can contribute to EoE symptoms.
