The knowledge of the basic principles of lymphatic function, still remains, to a large degree, rudimentary and will require significant research efforts. Recent studies of the physiology of the mesenteric lymphatic vessels (MLVs) suggested the presence of an endothelium-derived relaxing factor (EDRF) other than nitric oxide. In this study we tested the hypothesis that lymphatic endothelium-derived histamine relaxes MLVs. We measured and analyzed parameters of lymphatic contractility in isolated and pressurized rat mesenteric lymphatic vessels under control conditions and after pharmacological blockade of nitric oxide by Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME, 100 μM) or/and histamine production by α-methyl-DL-histidine dihydrochloride (α-MHD, 10 μM). Effectiveness of α-MHD was confirmed immunohistochemically. We also used immunohistochemical labeling and western blot analysis of the histamine-producing enzyme, histidine decarboxylase (HDC). Additionally we blocked HDC protein expression in MLVs by transient transfection with vivo-morpholino oligos. We found that only combined pharmacological blockade of nitric oxide and histamine production completely eliminates flow-dependent relaxation of lymphatic vessels, thus confirming a role for histamine as an EDRF in MLVs. We also confirmed the presence of histidine decarboxylase and histamine inside lymphatic endothelial cells. Our study supports a role for histamine as an EDRF in MLVs.
