Fibrosis: mechanisms and targets

Fibrosis is characterized by the excess accumulation of extracellular matrix components, leading to disrupted tissue function in affected organs. Fibrosis can develop in nearly every part of the body, and is an important driver of end-stage organ failure and death in a variety of chronic diseases. The high proportion of individuals affected by organ fibrosis and the associated morbidity and mortality of fibrotic disease has led to ongoing efforts to understand the mechanisms involved in the activation of fibroblasts and abnormal deposition of extracellular matrix, with the aim of developing new therapeutic strategies to prevent or treat fibrotic disease. The goal of this collection is to highlight the latest developments in this field and provide insights into the pathological processes of fibrosis and efforts to identify therapeutic avenues.

The collection consists of Reviews and Research articles from several Nature journals, describing the latest advances in fibrosis research in various organs, including the liver, kidney, heart, skin and lung. It also includes relevant News and Opinion articles and additional content, including a selection of peer-reviewed procedures from Nature Protocols, and a PrimeView, which summarizes the main features of systemic sclerosis.

Liver fibrosis in 2015: Crucial steps towards and effective treatment 

Klaas Poelstra

Nature Reviews Gastroenterology & Hepatology: Year-in-Review commentary 

In 2015, new tools were developed to modulate fibroblast and macrophage activity to halt liver fibrogenesis and stimulate resolution. Essential factors for resolution were identified and clinical trials yielded potential new antifibrotic drugs. Although innovations were made this year, clinical trials are still hampered by the lack of methods to monitor disease progression.

 

Renal fibrosis in 2015: Understanding the mechanisms of kidney fibrosis 

Dong Zhou & Youhua Liu

Nature Reviews Nephrology: Year-in-Review commentary

The year 2015 has seen great progress in the renal fibrosis field, as key studies began to build a consensus on the importance of epithelial-to-mesenchymal transition, cell cycle arrest, and defective metabolism in the pathogenesis of kidney fibrosis. New findings also point to a role of developmental signalling in renal fibrogenesis.

 

The NASH drug dash 

Kelly Rae Chi

Nature Reviews Drug Discovery: News and Analysis 

Intercept Pharmaceuticals has announced plans for the first ever pivotal trial in non-alcoholic steatohepatitis (NASH), setting a high bar for a growing pipeline of drugs against the liver disease.

 

Lung mapping seeks to crack microbial code in cystic fibrosis 

Shraddha Chakradhar

Nature Medicine: News

In diseases such as cystic fibrosis, the movement of certain microbes to certain lung regions can determine the extent of disease and be responsible for flare-ups. Understanding the location and types of bacteria in the lungs could lead to drastically more-effective treatments for potentially fatal lung infections in people with cystic fibrosis. 

 

The cystic fibrosis drug market 

Basharut A. Syed & Bashar Hamad

Nature Reviews Drug Discovery: News and Analysis 

Cystic fibrosis (CF), also known as mucoviscidosis, is a lethal common autosomal-recessive disorder. The highest incidence of CF is among Caucasians of northern European descent, occurring in approximately 1 in 2,500 live births.Worldwide, over 75,000 people are affected by the condition.

 

False dawn for cystic fibrosis disease modifiers? 

David Holmes

Nature Reviews Drug Discovery: News and Analysis 

Recent results have cast doubt over how effective a breakthrough class of cystic fibrosis drugs can be in patients with the most common form of the disease.
