Interaction among IgE-mediated hypersensitivity reaction, PCA reaction and delayed hypersensitivity reaction (at local skin sites of monkeys). 1979

T Yoshida, and H Mikawa, and K Shinomiya, and T Hirao, and R Okuda

The effect of the IgE-mediated reaction on the passive cutaneous anaphylaxis (PCA) reaction was studied at local skin sites of monkeys, and we found that the IgE-mediated reaction appeared to enhance the PCA reaction. Interactions among IgE-mediated reaction, PCA reaction and delayed hypersensitivity reaction were also determined. Contact dermatitis induced with DNCB was utilized as the delayed hypersensitivity reaction. The IgE-mediated reactior or PCA reaction, as well as simple serum irritation, enhanced the delayed hypersensitivity reaction. It is thus assumed that the IgE-mediated reaction enhances the PCA reaction and that this in turn accelerates the delayed hypersensitivity reaction.

UI MeSH Term Description Entries
D006967 Hypersensitivity Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen. Allergy,Allergic Reaction,Allergic Reactions,Allergies,Hypersensitivities,Reaction, Allergic,Reactions, Allergic
D006968 Hypersensitivity, Delayed An increased reactivity to specific antigens mediated not by antibodies but by sensitized T CELLS. Hypersensitivity, Tuberculin-Type,Hypersensitivity, Type IV,Tuberculin-Type Hypersensitivity,Type IV Hypersensitivity,Delayed Hypersensitivity,Delayed Hypersensitivities,Hypersensitivity, Tuberculin Type,Tuberculin Type Hypersensitivity,Tuberculin-Type Hypersensitivities,Type IV Hypersensitivities
D007073 Immunoglobulin E An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE). IgE
D010323 Passive Cutaneous Anaphylaxis An evanescent cutaneous reaction occurring when antibody is injected into a local area on the skin and antigen is subsequently injected intravenously along with a dye. The dye makes the rapidly occurring capillary dilatation and increased vascular permeability readily visible by leakage into the reaction site. PCA is a sensitive reaction for detecting very small quantities of antibodies and is also a method for studying the mechanisms of immediate hypersensitivity. Anaphylaxis, Passive Cutaneous,PCA,Cutaneous Anaphylaxis, Passive
D003877 Dermatitis, Contact A type of acute or chronic skin reaction in which sensitivity is manifested by reactivity to materials or substances coming in contact with the skin. It may involve allergic or non-allergic mechanisms. Contact Dermatitis,Dermatitis Venenata,Eczema, Contact,Hypersensitivity, Contact,Sensitivity, Contact,Contact Dermatitides,Contact Eczema,Contact Hypersensitivities,Contact Hypersensitivity,Contact Sensitivities,Contact Sensitivity,Dermatitides, Contact,Hypersensitivities, Contact,Sensitivities, Contact
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D000882 Haplorhini A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes). Anthropoidea,Monkeys,Anthropoids,Monkey
D012882 Skin Tests Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity. Skin Test,Test, Skin,Tests, Skin
