Detailed explanation-1: -Type I hypersensitivity is also known as an immediate reaction and involves immunoglobulin E (IgE) mediated release of antibodies against the soluble antigen. This results in mast cell degranulation and release of histamine and other inflammatory mediators.
Detailed explanation-2: -Accumulating evidence suggests the importance of the innate immune system in the development of allergy susceptibility.
Detailed explanation-3: -A hypersensitivity reaction happens when the immune system mistakenly identifies harmless substances as harmful.
