WebDec 13, 2024 · The H 4 receptor is the latest histamine receptor described in this family. The H 4 receptor is a Gα i/o ‐coupled receptor, and its agonists‐induced stimulation leads to an inhibition of AC and downstream cAMP responsive elements as well as the activation of MAPK and PLC with calcium mobilization (Shahid et al., 2009; Panula et al., 2015).
