Hypersensitivity - Wikipedia Type I hypersensitivity is also known as immediate hypersensitivity because it occurs within seconds to minutes of exposure Type II (cytotoxic) and type III (immune complex) occur within hours of exposure Type IV is also known as delayed-type hypersensitivity (DTH) and occurs days after exposure
Hypersensitivity Reactions: Types, Symptoms Treatment There are four types of hypersensitivity reactions, which can range from mild allergies to life-threatening emergencies Hypersensitivities can also cause long-term conditions, like autoimmune diseases It might not seem like an itchy poison ivy rash, lupus and asthma have much in common

Hypersensitivity- Introduction, Causes, Mechanism and Types Explore hypersensitivity reactions, including their types, underlying mechanisms, and causes Understand how the immune system can overreact, leading to various allergic responses
Hypersensitivity Reactions: Types, Causes, and Treatments There are four different types of hypersensitivity reactions A hypersensitivity reaction is commonly referred to as an “allergy ” A hypersensitivity reaction involves an abnormal response to a foreign body, or an antigen The body can mount one of four different immune responses to this antigen
Hypersensitivity - an overview | ScienceDirect Topics Hypersensitivity is the 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
Type III Hypersensitivity Reaction - StatPearls - NCBI Bookshelf A hypersensitivity reaction is an exaggerated or dysregulated immune response to an antigen, leading to tissue injury in the host These reactions typically occur in individuals previously sensitized to the antigen, implicating memory immune components in the response
