Histamine 63-72 interleukin 1 complex Mus musculus 0-4 2312155-4 1990 IL-1 production was significantly blocked by either an H1 anti-histamine, diphenhydramine, or H2 anti-histamine ranitidine, in the absence of any exogenous histamine. Histamine 102-111 interleukin 1 complex Mus musculus 0-4 2312155-5 1990 Addition of exogenous histamine accentuated the IL-1 production by macrophages as a function of its dose. Histamine 22-31 interleukin 1 complex Mus musculus 48-52 2312155-6 1990 These results suggest that IL-1 production by mouse peritoneal macrophages is regulated by histamine synthesized in the system per se and that the effect of histamine is dependent on both H1 and H2 histamine receptors located on the surface of the cells. Histamine 91-100 interleukin 1 complex Mus musculus 27-31
