Leukotrienes (LTB4 and LTD4): in vitro effects on human lymphocyte proliferation and transformation. 1984

J E Guttery, and A Tilden, and D K Herron, and P Gallagher, and S R Baker, and E W Ades

The effects of leukotrienes LTD4 and LTB4 on cell proliferation were assessed in a human in vitro lymphocyte transformation assay in the presence of optimal concentrations of PHA, Con A and PWM. Leukotriene D4 and LTB4 (10(-6) to 10(-11) M) did not alter the basal or mitogen-stimulated response. We therefore conclude that these two agents do not play a role in the modulation of human lymphocyte blastogenesis.

UI MeSH Term Description Entries
D007975 Leukotriene B4 The major metabolite in neutrophil polymorphonuclear leukocytes. It stimulates polymorphonuclear cell function (degranulation, formation of oxygen-centered free radicals, arachidonic acid release, and metabolism). (From Dictionary of Prostaglandins and Related Compounds, 1990) 5,12-HETE,5,12-diHETE,LTB4,Leukotriene B,Leukotriene B-4,Leukotrienes B,5,12 HETE,5,12 diHETE,B-4, Leukotriene,Leukotriene B 4
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci.

D013189 SRS-A A group of LEUKOTRIENES; (LTC4; LTD4; and LTE4) that is the major mediator of BRONCHOCONSTRICTION; HYPERSENSITIVITY; and other allergic reactions. Earlier studies described a "slow-reacting substance of ANAPHYLAXIS" released from lung by cobra venom or after anaphylactic shock. The relationship between SRS-A leukotrienes was established by UV which showed the presence of the conjugated triene. (From Merck Index, 11th ed) Slow Reacting Substance of Anaphylaxis
