The histamine H4 receptor is, like the other three histamine receptors, a member of the G protein-coupled receptor superfamily.[1][2][3]

[edit] Location
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.[4] It is also expressed in the colon, liver, lung, small intestine, spleen, testes, thymus, tonsils, and trachea.[5]
[edit] Functions
They have been shown to mediate mast cell chemotaxis.[6] It seems to do this by the mechanism of Gi-coupled decrease in cAMP. [7]
[edit] Pharmacologic potential
By inhibiting the H4 receptor, asthma and allergy may be treated.[7]
