Histamine receptor family consists of four members, namely, H1, H2, H3, and H4. The histamine H4 receptor is the most recently identified G protein-coupled histamine receptor that binds to several neuroactive drugs, including amitriptyline and clozapine. So far, H4 receptors have been found only on haematopoietic cells. This signifies its important role as a drug target for the treatment of inflammatory diseases.

Application Examples
Figure 1. Histamine-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/H4/Gα15 and CHO-K1/Gα15 cells. The cells were loaded with Calcium-4 prior to stimulation with a H4 receptor agonist, Histamine. The intracellular calcium change was measured by FlexStation. The relative fluorescent units (RFU) were plotted against the log of the cumulative doses (10-fold dilution) of Histamine (Mean ± SD, n = 2). The EC50 of Histamine on H4 co-expressing with Gα15 in CHO-K1 cells was 147 nM. The S/B of Histamine on H4 co-expressing with Gα15 in CHO-K1 cells was 39.
