Historically, ligands for GPCRs have been identified before their receptor counterparts. With the cloning revolution, several unidentified receptors have been found and were labelled as “orphan although it is widely accepted that medium‐chain fatty acids (MCFAs) can bind to and activate this receptor and 2. which ligands can be used as tool compounds to study the function and biology of this receptor CXCR2 and the adenosine A3 receptor (Gaidarov et al., 2018).

August 2022 "Despite the importance of members of the GPCR superfamily as targets of a broad range of effective medicines many GPCRs remain poorly characterised. GPR84 is an example. Expression of GPR84 is strongly up regulated in immune cells in a range of pro-inflammatory settings and clinical trials to treat idiopathic pulmonary fibrosis are currently ongoing using ligands with differing levels of selectivity and affinity as GPR84 antagonists. Although blockade of GPR84 may potentially prove effective also in diseases associated with inflammation of the lower gut there is emerging interest in defining if agonists of GPR84 might find utility in conditions in which regulation of metabolism or energy sensing is compromised. Here, we consider the physiological and pathological expression profile of GPR84 and, in the absence of direct structural information, recent developments and use of GPR84 pharmacological tool compounds to study its broader role and biology.
