Histidine 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 کاملBone marrow-derived mast cell differentiation is strongly reduced in histidine decarboxylase knockout, histamine-free mice.
Mast cells are differentiated in vitro from bone marrow precursors. In this study the development of bone marrow-derived mast cells was examined from histidine decarboxylase deficient (HDC-/-) and wild-type mice in the presence of IL-3. The number of non-adherent, tryptase- and c-kit-positive mast cells in bone marrow-derived cultures of HDC(-/-) mice was decreased compared to that of wild-type...
متن کاملCrucial role of histamine for regulation of gastric acid secretion ascertained by histidine decarboxylase-knockout mice.
Histidine decarboxylase (HDC) represents the sole enzyme that produces histamine in the body. The present work investigated the role of endogenous histamine in carbachol- and gastrin-induced gastric acid secretion with HDC-knockout (HDC-/-) mice. Acid secretion was measured in either mice subjected to acute fistula production under urethane anesthesia or conscious mice that had previously under...
متن کاملHistidine Decarboxylase Deficiency Causes Tourette Syndrome: Parallel Findings in Humans and Mice
Tourette syndrome (TS) is characterized by tics, sensorimotor gating deficiencies, and abnormalities of cortico-basal ganglia circuits. A mutation in histidine decarboxylase (Hdc), the key enzyme for the biosynthesis of histamine (HA), has been implicated as a rare genetic cause. Hdc knockout mice exhibited potentiated tic-like stereotypies, recapitulating core phenomenology of TS; these were m...
متن کاملThe regulation of histidine decarboxylase gene expression.
Histamine is a biogenic amine, which is involved in a variety of biologic processes comprising inflammation, allergic responses, neurotransmission and regulation of gastric acid secretion. The key enzyme for the generation of histamine is histidine decarboxylase (HDC), which converts the amino acid L-histidine to histamine. In this article, we review the history, biochemistry and molecular biol...
