Lysophosphatidic acid and itsreceptors: Role in bronchial asthma pathogenesis

Abstract

Lysophosphatidic acid (LPA) is a biologically active lipid mediator that regulates a number ofsignaling pathways involved in the pathogenesis of bronchial asthma. Attention to studying the relationship of LPA with LPA receptors (LPARs) and ion channels with transient receptor potential (TRP) is caused by their role in the initiation and development of bronchial obstruction, which suggests the development of new effective strategies for the treatment of bronchial asthma through blocking LPA synthesis and/or regulation of the activity of the ligand-receptor relationship.The aim of the review. To summarize ideas on the role of lysophosphatidic acid and its receptors in the pathogenesis of bronchial asthma based on the analysis of articles published in English in 2020–2023 from the PubMed database.Conclusion. The review summarizes recent literature data on the chemical structure, biosynthetic pathways and LPA receptors. It presents the information on the role of LPA, LPARs andTRP channels inthepathogenesis of bronchial asthma; summarizes the bronchial asthma therapeutic strategies targeting LPA, LPARs, andTRP channels. The review highlights not only a new perspective on understanding the mechanisms of initiation of asthmatic reactions, but also possible ways to manage them at the stage of correction of their development.
