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

Contents

Tissue distribution

H4 is highly expressed in bone marrow and white blood cells and regulates neutrophil release from bone marrow and subsequent infiltration in the zymosan-induced pleurisy mouse model.[4] It is also expressed in the colon, liver, lung, small intestine, spleen, testes, thymus, tonsils, and trachea.[5]

Function

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]

Therapeutic potential

By inhibiting the H4 receptor, asthma and allergy may be treated.[7]

The highly selective histamine H4 antagonist VUF-6002 is orally active and inhibits the activity of both mast cells and eosinophils in vivo,[8]and has antiinflammatory and antihyperalgesic effects.[9]
