Histamine is a monoamine signaling molecule that acts via four G-protein-coupled histamine receptors; H1, H2, H3 and H4. Histamine mediates numerous biological activities stimulated by various immunological and non-immunological stimuli, through differential expression of H1-4 on effector cells, such as mast cells and basophils.
Histamine has a critical role in immumomodulation and allergic diseases. Other biological activities include cell proliferation, differentiation, hematopoiesis, embryonic development, regeneration, wound healing, aminergic neurotransmission, secretion of pituitary hormones and regulation of gastrointestinal and circulatory functions.
