해설
Hypersensitivity is an exaggerated or inappropriate immune response to a substance. It involves elevated levels of IgE antibodies that react to specific allergens. This reaction can range from mild (like hay fever) to severe (like anaphylaxis). The condition involves immune cells releasing histamine and other inflammatory mediators, causing symptoms like itching, swelling, and respiratory distress.
• Types of Hypersensitivity:
- Type I: Immediate (IgE-mediated)
- Type II: Cytotoxic (IgG/IgM-mediated)
- Type III: Immune Complex
- Type IV: Delayed-type
hypersensitivity — An exaggerated or inappropriate immune response to a substance, characterized by elevated levels of IgE antibodies that react to specific allergens, causing symptoms like itching, swelling, and respiratory distress
immunodeficiency — A condition where the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent, making a person susceptible to infections
autoimmunity — A condition where the immune system mistakenly attacks healthy cells in the body, causing various diseases where the body's tissues are attacked by its own immune system
tolerance — The immune system's state of unresponsiveness to substances that would otherwise trigger an immune response, preventing harmful reactions to harmless substances
immunity — The body's ability to resist infection and disease through the actions of specific antibodies and sensitized white blood cells
