Mouse spleen cells were incubated for 24 hours in the presence of histamine (10(-13)-10(-3) M). Aliquots of the histamine free supernatants were intravenously injected into either syngenic or allogenic mice which were subsequently analysed by the Jerne plaque assay in respect of their specific IgM response against red blood cells from sheep. Depending on the histamine concentration during the preincubation and the mouse strain, the effects of the supernatants were found to be suppressive or potentiating. Both the histamine induced suppressor and potentiating factor are generated by T-cells and can be precipitated by (NH4)2SO4. These precipitates were fractionated by gel filtration which revealed a molecular weight of both factors in the range of 20 to 50 kDa. Both lymphokines were found to be sensitive to trypsin, low pH, and heat treatment but were not affected by neuraminidase. They do only interfere with the early events of the IgM response within 24 hours after the administration of the antigen. The conclusion is that the bidirectional modulation of the humoral immune response by histamine in mice is partially due to the induction of these lymphokines by a different efficacy of the histamine receptor activation at different T-cell subsets.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D008222	Lymphokines	Soluble protein factors generated by activated lymphocytes that affect other cells, primarily those involved in cellular immunity.	Lymphocyte Mediators,Mediators, Lymphocyte
D008815	Mice, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D006632	Histamine	An amine derived by enzymatic decarboxylation of HISTIDINE. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and also a centrally acting neurotransmitter.	Ceplene,Histamine Dihydrochloride,Histamine Hydrochloride,Peremin
D000276	Adjuvants, Immunologic	Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

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.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.	Species Specificities,Specificities, Species,Specificity, Species
D013491	Suppressor Factors, Immunologic	Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-J) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory.
