Скачать или смотреть Hypersensitivity Reaction | Most easy explanation!

Dive into the fascinating world of hypersensitivity reactions! This video breaks down what happens when your immune system mistakes a harmless substance for a dangerous invader, leading to tissue damage, inflammation, and uncomfortable symptoms.

​We'll cover the four main types of hypersensitivity reactions :

​Type I (Immediate/Anaphylactic):
The rapid response involving IgE antibodies and mast cells. Learn how allergies, asthma, and anaphylaxis fit into this category.

​Type II (Cytotoxic):
Reactions mediated by IgG or IgM antibodies targeting antigens on cell surfaces, often leading to cell destruction (e.g., blood transfusion reactions).

​Type III (Immune Complex):
When antigen-antibody complexes form in the blood and deposit in tissues, triggering damaging inflammation (e.g., serum sickness, lupus).

​Type IV (Delayed-Type/Cell-Mediated):
A slower reaction driven by T-cells and macrophages, not antibodies (e.g., contact dermatitis from poison ivy, the TB skin test).
