Histamine H4 Receptors

Supporting information

Histamine H4 receptors are Gαi/o-protein-coupled receptors that were initially cloned in 2000. H4 receptors are expressed at high levels in the gastrointestinal tract, spleen, thymus, medullary cells, bone marrow and peripheral hematopoietic cells, including eosinophils, basophils, mast cells, T lymphocytes, leukocytes and dendritic cells. Moderate expression levels are detected in the brain, heart, liver and lung.

H4 receptors have an important role in inflammation, hematopoiesis and immunity and their expression is regulated by stimuli such as IFN, TNF-α and IL-6. Activation of this receptor mediates chemotaxis of mast cells and eosinophils and also controls cytokine release from dendritic and T cells. Furthermore, H4 receptors have a role in the differentiation of myeloblasts and promyelocytes.

The human gene encoding the H4 receptor is localized to chromosome 18q11.2
