Histamine Genomics and Metabolomics

Research output: Chapter in Book/Report/Conference proceedingChapter


Histamine, one of the most abundantly studied general mediators, is a 112 Da biogenic amine generated by histidine decarboxylase (HDC) from L-histidine. Histamine binds to at least four different G-protein-associated plasma membrane receptors (H1-H4) with dissimilar tissue expression patterns and various biological functions. It plays an important role in the regulation of immune and inflammatory processes and, based on recent studies, is involved in malignant and normal cell proliferation. Both synthetizing and degradating enzymes, as well as histamine receptors, reveal significant, functionally relevant genetic polymorphism. The phenotype of the gene-targeted HDC-'knock-out' mice suggests that histamine, part of metabolome, is a major player in the regulation of mammalian physiology and pathophysiology.
