Pharmacological targeting of adaptor proteins in chronic inflammation.

Abstract

Inflammation, a biological response of the immune system, can be triggered by various factors such as pathogens, damaged cells, and toxic compounds. These factors can lead to chronic inflammatory responses, potentially causing tissue damage or disease. Both infectious and non-infectious agents, as well as cell damage, activate inflammatory cells and trigger common inflammatory signalling pathways, including NF-κB, MAPK, and JAK-STAT pathways. These pathways are activated through adaptor proteins, which possess distinct protein binding domains that connect corresponding interacting molecules to facilitate downstream signalling. Adaptor molecules have gained widespread attention in recent years due to their key role in chronic inflammatory diseases. In this review, we explore potential pharmacological agents that can be used to target adaptor molecules in chronic inflammatory responses. A comprehensive analysis of published studies was performed to obtain information on pharmacological agents. This review highlights thetherapeutic strategies involving small molecule inhibitors, antisense oligonucleotide therapy, and traditional medicinal compounds thathave been found to inhibit the inflammatory response and pro-inflammatory cytokine production. These strategies primarily block the protein-protein interactions in the inflammatory signaling cascade.Nevertheless, extensive preclinical studies and risk assessment methodologies are necessary to ensure their safety.
