Idiopathic pulmonary fibrosis-relevant signaling pathway targets

Idiopathic pulmonary fibrosis-relevant signaling pathway targets is a descriptive category used to classify molecular entities and signaling cascades that contribute to the pathogenesis of Idiopathic Pulmonary Fibrosis (IPF), a progressive and fatal lung disease [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4319193/]. This term is frequently employed as a placeholder for therapeutic targets that have not been fully molecularly identified or for drugs that demonstrate anti-fibrotic efficacy through the simultaneous modulation of multiple pathways. Key signaling networks involved in this category include the Transforming growth factor beta (TGF-beta) pathway, which is the master regulator of fibrosis, as well as the Wnt/beta-catenin, Hedgehog, and Notch pathways [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3411131/]. Additionally, various receptor tyrosine kinases (RTKs) such as those for Platelet-derived growth factor (PDGF) and Fibroblast growth factor (FGF) are critical nodes within this signaling landscape [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4319193/]. Drugs like Pirfenidone are often associated with these unknown targets because their precise primary binding partners remain elusive despite their proven clinical utility in slowing disease progression [https://pubmed.ncbi.nlm.nih.gov/21571510/]. Characterizing these unidentified targets is a major focus of current research to improve the precision and safety of future IPF treatments.

The mechanism of action for agents in this category typically involves the pleiotropic modulation of pro-fibrotic and pro-inflammatory signaling cascades, such as the inhibition of Transforming growth factor beta production and the reduction of fibroblast-to-myofibroblast transition, without a single defined molecular binding partner [https://pubmed.ncbi.nlm.nih.gov/26303307/].
