Scientists at IRB Barcelona<\/a>\u2019s Cellular Plasticity and Disease<\/a> lab, led by\u00a0Dr. Manuel Serrano, have described the pivotal role of iron accumulation in the development of fibrotic diseases. The study, published in Nature Metabolism, points oints to a new therapeutic approach for the treatment of these pathologies, which represent 45% of all mortality in developed countries.<\/strong><\/p>\n

Fibrosis is associated with various chronic and life-threatening conditions, including pulmonary fibrosis, liver cirrhosis, kidney disease, and cardiovascular diseases, among others. These conditions collectively contribute to a substantial portion of mortality in developed countries, making fibrotic diseases a critical health problem requiring attention, research, and innovative approaches for diagnosis and treatment.<\/p>\n

Now, iIn this work, researchers have studied the link between iron accumulation, senescence (a phase where cells neither divide nor die) and the Senescence-Associated Secretory Phenotype (SASP)\u2014a communication system in ageing cells that prompts them to release harmful molecules. SASP has been associated with various age-related diseases, including fibrosis.<\/p>\n

The results show the potential of iron detection via magnetic resonance imaging (MRI) for non-invasive assessment of fibrotic burden in patients with renal fibrosis. Additionally, the team uncovers the potential of chemical compounds able to remove the accumulated iron, such as deferiprone (a clinically approved drug) to prevent fibrosis, thereby pointing to a new approach for treating fibrotic diseases.<\/p>\n

“Our study establishes iron accumulation as a clinically exploitable driver of pathological senescence and fibrosis and paves the way for new strategies in the early detection and treatment of fibrotic diseases,” says\u00a0Dr. Mate Maus<\/strong>. Dr. Maus is the leading author of the study, together with Dr. Serrano, and an IRB Barcelona alumnus. He is currently leading the\u00a0Aging and Cancer lab<\/a>\u00a0at the Vall d’Hebron Institute of Oncology (VHIO), in Barcelona, where he continues investigating age-related metabolic changes that promote chronic diseases and cancer.<\/p>\n

Systemic iron metabolism<\/strong><\/h3>\n

Iron accumulation had previously been reported in association with several fibrotic disorders. On the basis of the findings of this study, the scientists suggest it might be a common feature of most fibrotic diseases. This research highlights two distinct roles of iron in fibrogenesis. First, it shows that excessive extracellular iron can initiate fibrogenesis. For instance, this may occur in fibrotic diseases associated with small vascular injuries, where iron release from the vasculature may be a constant trigger for fibrogenesis Second, the study indicates that iron accumulation is an intrinsic characteristic of senescent cells, even under normal levels of extracellular iron. The accumulation of iron is a key event driving the SASP and its pro-fibrotic effects on the surrounding tissue.<\/p>\n

Halting fibrosis<\/strong><\/h5>\n

By addressing iron accumulation in senescent cells, the researchers aim to alleviate the SASP and, consequently, halt the progression of fibrosis. \u201cAlthough these findings mark a significant step forward in our understanding of fibrotic diseases, further research and clinical validation are crucial before translating these insights into tangible treatments,” concludes\u00a0Dr. Serrano<\/strong>.<\/p>\n
