Type IV (Cell Mediated) Hypersensitivity- Mechanism and Examples

by
Type IV (Cell Mediated) Hypersensitivity- Mechanism and Examples

Hypersensitivity refers to increased reactivity or exaggerated immune response of a host to an antigen to which it has been previously exposed. According to the most widely accepted classification of Gell and Coombs, there are four main types of hypersensitivity reactions as type I, II, III and IV. Type I, II and III are immunoglobulin-mediated … Read more Type IV (Cell Mediated) Hypersensitivity- Mechanism and Examples

Type III (Immune Complex) Hypersensitivity- Mechanism and Examples

by
Type III (Immune Complex) Hypersensitivity- Mechanism and Examples

The term hypersensitivity denotes a condition in which an exaggerated immune response of a host results in inappropriate reactions that leads to destruction of host tissues. According to the most widely accepted classification of Gell and Coombs, there are four main types of hypersensitivity reactions as type I, II, III and IV. Type I, II … Read more Type III (Immune Complex) Hypersensitivity- Mechanism and Examples

by
Type 1 (Anaphylactic) Hypersensitivity Reaction

Hypersensitivity is increased reactivity or increased sensitivity by the animal body to an antigen to which it has been previously exposed. The most widely adopted current classification is that of Coombs and Gellthat designates immunoglobulin-mediated (immediate) hypersensitivity reactions as types I, II, and III, and lymphoid cell-mediated (delayed-type) hypersensitivity/cell-mediated immunity as a type IV reaction. … Read more Type 1 (Anaphylactic) Hypersensitivity Reaction

What is Immunology?

Immunology

What is Immunology? Immunology is the study of how the body responds to foreign substances and fights off infection and other disease. Immunologists study the molecules, cells, and organs of the human body that participate in this response. Immunity Immunity is a condition of being able to resist a particular disease especially through preventing the … Read more What is Immunology?

Hypersensitivity- Introduction, Causes, Mechanism and Types

Introduction Hypersensitivity is increased reactivity or increased sensitivity by the animal body to an antigen to which it has been previously exposed. The term is often used as a synonym for allergy, which describes a state of altered reactivity to an antigen. Hypersensitivity has been divided into categories based upon whether it can be passively … Read more Hypersensitivity- Introduction, Causes, Mechanism and Types
