WebMar 4, 2024 · In this study, we identified a novel histamine production mechanism by the interaction of macrophages and Th2 cells, and revealed that Th2 cells and macrophages cooperatively induce nasal allergic inflammation through histamine signaling. Materials and methods Reagents [1][2]Histidine decarboxylase is the sole member of the histamine synthesis pathway, producing histamine in a one-step reaction. Histamine cannot be generated by any other known enzyme.[3] HDC is therefore the primary source of histamine in most mammalsand eukaryotes. See more The enzyme histidine decarboxylase (EC 4.1.1.22, HDC) is transcribed on chromosome 15, region q21.1-21.2, and catalyzes the decarboxylation of histidine to form histamine. In mammals, histamine is an important See more HDC decarboxylates histidine through the use of a PLP cofactor initially bound in a Schiff base to lysine 305. Histidine initiates the reaction by displacing lysine 305 and forming an See more HDC can be inhibited by α-fluoromethylhistidine and histidine methyl ester.
