It is also called DTH(delayed type hypersensitivity) is cell mediated instead of antibody
Allergen
4
there are 4. Viruses, Bacteria, Fungi, and Protoza
IAIB (4)
There are mainly 4 types ofScience... in which Biology,Chemistryand Physics are 3 Main categories type and Maths is other type.
Type IV Hyper sensitivity. AKA delayed hypersensitivity. Can be classified into: -contact -tuberculin -granuloma
Type I hypersensitivity reaction http://en.wikipedia.org/wiki/Asthma
Type II hypersensitivity is also known as cytotoxicity hypersensitivity and it may affect variety of organs and tissues. The antigens are endogenous and exogenous chemicals. Type III Hypersensitivity complex type of hypersensitivity and it may affect individual organs like skin, Liver etc.
Yes, in type I hypersensitivity IgE antibodies are bound to mast cells.
generally, pernicious anemia, if autoimmune, is a type 2 hypersensitivity
The most common type of immediate hypersensitivity is type I hypersensitivity, also known as allergic reactions. This type of hypersensitivity involves the production of IgE antibodies in response to an allergen, which leads to the release of histamine and other mediators that cause symptoms such as itching, hives, and anaphylaxis.
Hypersensitivity
I think type 2....
Type IV
Hypersensitivity reactions are classified into four categories: Type I (immediate hypersensitivity), which involves IgE-mediated responses leading to allergic reactions; Type II (antibody-mediated cytotoxicity), where antibodies target specific cells; Type III (immune complex-mediated), characterized by the formation of antibody-antigen complexes that trigger inflammation; and Type IV (delayed-type hypersensitivity), which is mediated by T cells and manifests hours to days after exposure to the allergen. Each type involves distinct immune mechanisms and clinical manifestations.
contact dermatitis
B-cells primarily modulate hypersensitivity types I, II, and III. In type I hypersensitivity, B-cells produce IgE antibodies in response to allergens, leading to allergic reactions. In type II, B-cells generate IgG or IgM antibodies that target specific cell surfaces, resulting in cytotoxic effects. Type III hypersensitivity involves the formation of immune complexes by B-cell-produced antibodies, which can deposit in tissues and trigger inflammation.
