Fibrogenic Disorders in Human Diseases: From Inflammation to Organ Dysfunction

Fibrosis is an inadequate response to tissue stress with very few therapeutic options to prevent its progression to organ dysfunction. There is an urgent need to identify drugs with a therapeutic potential for fibrosis, either by designing and developing new compounds or by repurposing drugs already in clinical use which were developed for Other indications. In this Perspective, we summarize some pathways and biological targets involved in fibrosis development and maintenance, focusing on common mechanisms between organs and diseases. We review the therapeutic agents under experimental development, clinical trials, or in clinical use for the treatment of fibrotic disorders, evaluating the reasons for the discrepancies observed between preclinical and clinical results. We also discuss the improvement that we envision in the development of therapeutic molecules able to achieve improved potential for treatment, including indirect modulators, targeting approaches, or drug combinations.
