Gourt Home::Gourt :: H4 receptor
The H4 histamine receptor was first published by Nguyen et al in March of 2001, who also published the gene encoded it in a search of the GenBank databases. Like the other three histamine receptors, it is also a G protein-coupled receptor.
Where Found
H4 is highly expressed in bone marrow and white blood cells and regulates zymosan-induced neutrophil release from bone marrow and subsequent infiltration in the pleurisy model along with L-selectin. It is also expressed in the colon, liver, lung, small intestine, spleen, testes, thymus, tonsils, and trachea.
Functions
They have been shown to mediate mast cell chemotaxis. ...and more
