Chronic kidney disease (CKD) is a global public health problem, involving about 10% of the global population. Unfortunately, there are currently no effective drugs. Kidney fibrosis is the main pathology of CKD, where integrins play crucial roles in renal fibrogenesis. Recently, Bexotegrast (PLN-74809) as a dual integrin αvβ1/αvβ6 inhibitor could reduce the degree of lung fibrosis in patients with idiopathic pulmonary fibrosis. However, the role of PLN-74809 remains unclear in fibrotic kidney disease. Here, we have revealed that PLN-74809 administration dose-dependently delayed the progression of renal fibrosis in both adenine diet- and unilateral ureteral obstruction (UUO)-induced mice. Mechanistically, PLN-74809 targeted integrin αvβ1/αvβ6 to inhibit FAK/Src/Akt/β-catenin cascade in fibrotic kidneys. In summary, our results for the first time highlighted the αvβ1/αvβ6 inhibitor PLN-74809 exerted potential therapeutic against kidney fibrosis.

Renal fibrosis is the most common pathway for the development of end-stage renal disease (ESRD) in various kidney diseases. Currently, the treatment options for renal fibrosis are limited. Ferroptosis is iron-mediated lipid peroxidation, triggered mainly by iron deposition and ROS generation.

In end-stage kidney disease requiring hemodialysis, patients at nutritional risk have a poor prognosis. The gut microbiota is important for maintaining the nutritional status of patients. However, it remains unclear whether an altered gut microbiota correlates with increased nutritional risk in patients undergoing hemodialysis.

Background: Patients with end-stage kidney disease (ESKD) have high rates of gastrointestinal bleeding due to several risk factors including platelet dysfunction, comorbid illness, and use of antiplatelet medications. Proton pump inhibitors (PPIs) reduce gastrointestinal bleeding and are recommended for high-risk patients such as those prescribed dual antiplatelet therapy (DAPT). Whether inappropriate duration of DAPT therapy and/or lack of appropriate PPI use contribute to the known elevated risk of gastrointestinal bleeding in hemodialysis patients is not known.
