Defective Angiogenesis in the Inflammatory Granulation Tissue in Histidine Decarboxylase–deficient Mice but not in Mast Cell–deficient Mice
We have analyzed the role of histamine in the angiogenesis of the granulation tissue in histidine decarboxylase-deficient (HDC(-/-)) mice, mast cell-deficient mice (WBB6F1-W/W(V)), and their corresponding wild-type mice (HDC(+/+) and WBB6F(1)(+/+)). In HDC(+/+) mice, subcutaneous implantation of a cotton thread in the dorsum induced granulation tissue formation with angiogenesis, while the topi...
متن کاملLack of histamine alters gastric mucosal morphology: comparison of histidine decarboxylase-deficient and mast cell-deficient mice.
Histamine plays an important role in the regulation of gastric acid secretion; however, its role in maintenance of gastric morphology remains unclear. To clarify the necessity of histamine for gastric mucosal development and maintenance, we evaluated two different kinds of mice that lacked either mast cells (one of the gastric histamine-producing cell types) or histidine decarboxylase (HDC; a h...
متن کاملHistidine Decarboxylase Deficiency Prevents Autoimmune Diabetes in NOD Mice
Recent evidence has highlighted the role of histamine in inflammation. Since this monoamine has also been strongly implicated in the pathogenesis of type-1 diabetes, we assessed its effect in the nonobese diabetic (NOD) mouse model. To this end, we used mice (inactivated) knocked out for the gene encoding histidine decarboxylase, the unique histamine-forming enzyme, backcrossed on a NOD genetic...
متن کاملHistidine decarboxylase in Enterobacteriaceae revisited.
With a modification of Taylor's decarboxylation broth, histidine decarboxylase was detected in Enterobacter aerogenes, Morganella morganii, Raoultella ornithinolytica, and some strains of Citrobacter youngae and Raoultella planticola. This method provides a useful confirmatory test for identification of E. aerogenes strains.
متن کاملHistidine Decarboxylase in Hyaline Membrane
During the latter part of pregnancy, the foetal rat produces large quantities of histamine which may be concerned with the growth of the foetus (Kahlson and Rosengren, 1959). Kahlson (1960) reported increased formation of histamine by the human foetus as well: recently Davis (1961) suggested that the antagonism of such excess histamine might account for the beneficial effect of an antihistamine...
