Types of Hypersensitivity

🎥 Title: Understanding Types of Hypersensitivity Reactions 📘 Description: In this video, we break down the four types of hypersensitivity reactions as defined by the Gell and Coombs classification. These immune system responses can result from allergies, autoimmunity, and other conditions. 🔍 Topics Covered: 1️⃣ Type I: Immediate Hypersensitivity Triggered by allergens (e.g., pollen, dust). Involves IgE antibodies, mast cells, and histamine release. Examples: Anaphylaxis, asthma, hay fever. 2️⃣ Type II: Cytotoxic Hypersensitivity Antibody-mediated destruction of cells. Involves IgG and IgM antibodies. Examples: Hemolytic anemia, blood transfusion reactions. 3️⃣ Type III: Immune Complex-Mediated Hypersensitivity Formation of antigen-antibody complexes. Causes inflammation and tissue damage. Examples: Serum sickness, lupus. 4️⃣ Type IV: Delayed-Type Hypersensitivity T-cell mediated, occurring 24–72 hours after exposure. Examples: Tuberculin skin test, contact dermatitis. 💡 Key Highlights: Understand how the immune system can overreact. Learn to differentiate between each type of hypersensitivity.
