IgE-मध्यस्थता मास्ट सेल डिग्रेन्युलेशन3. IgG/IgM-मध्यस्थता साइटोटोक्सिक प्रतिक्रिया।
Explanation:
Type I is allergy (IgE). Type II involves antibodies (IgG/IgM) binding to cell surfaces (cytotoxic). Type IV is a delayed hypersensitivity driven by T cells, not antibodies.
टाइप I एलर्जी (IgE) है। टाइप II में एंटीबॉडी (IgG/IgM) कोशिका सतहों से जुड़ते हैं। टाइप IV टी कोशिकाओं द्वारा संचालित एक विलंबित (delayed) अतिसंवेदनशीलता है।
