The histamine H4 receptor as a new therapeutic target for inflammation

Trends Pharmacol Sci. 2005 Sep;26(9):462-9. doi: 10.1016/


Following the sequencing of the human genome, data-mining efforts have revealed the existence of a new histamine receptor that is expressed at high levels in mast cells and leukocytes. The histamine H(4) receptor has a distinct pharmacological profile and the first compounds that act selectively on the H(4) receptor have been developed. Initial experiments in vivo with H(4) receptor antagonists indicate a role for the H(4) receptor in inflammatory conditions.
