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.
Detailed explanation-2: -Type IV hypersensitivity, often called delayed-type hypersensitivity, is a type of hypersensitivity reaction that can take a day or more to develop. Unlike the other types, it is not humoral (not antibody-mediated) but rather is a type of cell-mediated response.
Detailed explanation-3: -Immediate hypersensitivity (type I) is also known as immediate contact urticaria or contact urticaria syndrome, and the reaction occurs very rapidly. Common causes include insect bites and ingested peanuts. It is mediated by IgE antibodies, which bind to the surface of mast cells.
