Hipersensibilidade (Visão Geral) e Tipo 1 - Alergia #021

In this video, we'll understand the overview of hypersensitivity reactions and delve deep into the mechanisms of Type I Hypersensitivity (Allergy). If you have difficulty with Immunology, this lesson will practically clarify how the immune system overreacts to harmless antigens. We will detail the step-by-step process of the allergic reaction, addressing the tactical "fight" role of the cells involved, the importance of immunoglobulin E (IgE), mast cell activation, and how all this translates into the classic symptoms we see in clinical practice. What you will learn in this lesson: The general concept of Hypersensitivity in Immunology. How the sensitization phase occurs. The mechanism of mast cell degranulation. The difference between the immediate and late phases of Type 1 Hypersensitivity. 🔔 Subscribe to MedAulas to master Immunology and other health sciences!
