PG - 1596-1605 LID - 10.1111/jphp.13009 [doi] AB - OBJECTIVES: Pethidine hydrochloride (PH) and fentanyl citrate (FC) are opioid receptor agonists commonly used to treat pain clinically. PH and FC have been reported to have a high potential for pseudoallergic effects, but the underlying mechanism has not been well studied. MRGPRX2 is a novel atypical opioid receptor that is mainly expressed in human mast cells and considered to mediate drug-induced pseudoallergic reactions. This study aimed to investigate the allergy effect of these two opioid receptor agonists and the possible association of MRGPRX2 with this response. METHODS: HEK293-MRGPRX2/CMC assay, molecular docking assay, calcium mobilization assay, the test of beta-hexosaminidase, histamine and cytokine release assay were performed in this article. KEY FINDINGS: PH but not FC induced LAD2 cell activation and degranulation dose-dependently. Histamine, tumour necrosis factor (TNF)-alpha, interleukin (IL)-8, monocyte chemotactic protein 1 (MCP-1) and macrophage inflammatory protein (MIP-1beta) levels were upregulated by PH, but not FC. The PH-induced activation of mast cell was MRGPRX2-dependent. CONCLUSIONS: PH but not FC activated mast cells, leading to degranulation mediated via MRGPRX2 receptors, which could be greatly significant in future clinical applications of opioid receptor drugs.
