Cell-bound antibody reacts with antigen Type I to release physiologically active substance is which type of hypersensitivity reactions? What is not involved in type I reactions? Complement Free antibody reacts with antigen Type II associated with cell surfaces in which type of hypersensitivity reactions? What plays a major role in producing Complement tissue damage in type II reactions? Antibody reacts with soluble antigen to Type III form complexes that precipitate in the tissues in which type of hypersensitivity reaction? Complement a major role in Type III producing tissue damage in which type of hypersensitivity reactions? type of hypersensitivity reaction Type IV differs from the other three because sensitized T-cells rather than antibody are responsible for the symptoms that develop? What is not involved in type IV Complement hypersensitivity reactions? Which hypersensitivity types have Types I-III previously been referred to as immediate hypersensitivity because symptoms develop within a few minutes to a few hours? type of hypersensitivity has been Type IV called hypersensitivity because delayed its manifestations are not seen until hours after contact with antigen? The short lag time, usually seconds to Type I minutes, between exposure to antigen and the onset of clinical symptoms is the distinguishing feature of which type of hypersensitivity? What is the key reactant present in type IgE I, or immediate, hypersensitivity reactions? In type I hypersensitivity, what are the Atopic antigens, or allergens antigens called that trigger the formation of IgE? An inherited tendency to respond to Atopy naturally occurring inhaled and ingested
