IgE synthesis results from a complex interaction between T cells, B cells, and allergen presenting cells under the control of T cell and mast cell-/basophil-derived cytokines (IL-4, IL-5, and IL-6). IL-4 provides a first and crucial signal, which does not, however, suffice for the induction of IgE synthesis by human B cells. A second signal is required, which then leads to B cell activation and production of IgE+ B cells. Cognate as well as non-cognate T/B cell interactions or stimulation by Epstein-Barr (EB) virus infection, the ligand for CD40, ACTH, hydrocortisone etc. can provide this signal. Based on this concept of a multicomponent network new approaches may lead to the development of more effective strategies for the treatment of IgE-mediated allergic diseases.

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
D007073	Immunoglobulin E	An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE).	IgE
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000707	Anaphylaxis	An acute hypersensitivity reaction due to exposure to a previously encountered ANTIGEN. The reaction may include rapidly progressing URTICARIA, respiratory distress, vascular collapse, systemic SHOCK, and death.

D000938	Antigen-Presenting Cells	A heterogeneous group of immunocompetent cells that mediate the cellular immune response by processing and presenting antigens to the T-cells. Traditional antigen-presenting cells include MACROPHAGES; DENDRITIC CELLS; LANGERHANS CELLS; and B-LYMPHOCYTES. FOLLICULAR DENDRITIC CELLS are not traditional antigen-presenting cells, but because they hold antigen on their cell surface in the form of IMMUNE COMPLEXES for B-cell recognition they are considered so by some authors.

D001402	B-Lymphocytes	Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D015847	Interleukin-4	A soluble factor produced by activated T-LYMPHOCYTES that induces the expression of MHC CLASS II GENES and FC RECEPTORS on B-LYMPHOCYTES and causes their proliferation and differentiation. It also acts on T-lymphocytes, MAST CELLS, and several other hematopoietic lineage cells.
