ILD is an umbrella term, with idiopathic pulmonary fibrosis (IPF) being a prime focus because of its progressive and severe form. Out of 300 underlying etiologies, ILD is one of the major reasons for global morbidity and mortality. This review offers a comprehensive overview of six main categories of ILD covering autoimmune, idiopathic interstitial pneumonia, hypersensitivity pneumonitis, drug-induced, infection-related, and unclassified ILD that underscore the complexity of diagnosis and treatment challenges. This review also provides an evidence-based overview of recent advancements in the diagnosis and management of ILD, with precision pharmacotherapy, multidisciplinary care, and emerging therapeutic strategies. From clinical trial data, it also recommends the disease-specific use of pharmacological agents-such as pirfenidone and nintedanib for IPF, and mycophenolate mofetil for connective tissue disease-associated ILD. The manuscript also emphasizes the evolving role of non-pharmacological interventions, including the 6-minute walk test and pulmonary rehabilitation, in enhancing functional capacity and quality of life. To address the current global health concerns, topics of post-COVID-19 ILD and immune checkpoint inhibitor-associated lung disease are integrated. Additionally, future directions are explored, including the role of lung transplantation and novel antifibrotic therapies like anti-Transforming Growth Factor (TGF)-β antibody cocktails. Together, these insights aim to refine diagnostic precision, personalize treatment, and improve clinical outcomes across the heterogeneous ILD spectrum.</p>","PeriodicalId":8949,"journal":{"name":"Biomolecules & Therapeutics","volume":" ","pages":"785-803"},"PeriodicalIF":3.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12408203/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144844326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional treatments such as topical corticosteroids, calcineurin inhibitors, and systemic immunosuppressants provide symptomatic relief but often fail to provide long-term disease control. The emergence of targeted biologics and Janus kinase inhibitors has transformed AD management by offering more precise and effective therapeutic options.

In this review, we explore the evolving therapeutic landscape of AD, emphasizing the emerging role of biomarker-guided treatment strategies.

This review offers novel insight into how the convergence of biomarker research and therapeutic innovation can address current gaps in AD care.

Currently, there is an absence of efficacious therapeutic options available for the management of MASLD. Consequently, an in-depth exploration of the roles of FFAs and ferroptosis in the progression of MASLD may reveal hitherto unidentified therapeutic targets. In the study, we established an early lesion model of MASLD, namely NAFL, and comprehensive analyses of lipid metabolism, hepatocellular injury, iron homeostasis, and ferroptosis were performed. The HFD and FFAs treatment significantly elevated the expression of enzymes associated with lipid synthesis, including ACC1 and FASN, leading to enhanced lipid accumulation in hepatocytes. Additionally, HFD and FFAs resulted in increased iron loading and a reduction in the levels of the antioxidant enzyme GPX4, which ultimately triggers ferroptosis. In contrast, the administration of melatonin effectively inhibited the activity of lipid synthesis-related enzymes, decreased hepatic lipid deposition, alleviated free fatty acid-induced iron dysregulation, and mitigated liver damage. Mechanistically, melatonin has been shown to attenuate hepatocyte ferroptosis by modulating the KEAP1/NRF2/HO-1 pathway, which in turn diminishes free fatty acids-induced oxidative stress. In conclusion, melatonin alleviates MASLD progression by curbing FFAs-induced oxidative stress and ferroptosis.
