A tight link has been established between inflammation and cancer. Liver regeneration is a widely used model to study the correlation between inflammation and proliferation. IL-6 is essentially involved in liver regeneration and in cancer. Recently, IL-17A has been shown to regulate not only inflammation, but also cell proliferation. Here, we analyze the role played by IL-17A signaling in liver regeneration by comparing cell proliferation in Wild Type and IL-17RA mice. Partial hepatectomy experiments performed in IL-17RA mice showed a delay in expression of early-genes to prime the residual hepatocyte to proliferate, with subsequent delay in G/S-phase transition. We demonstrated that IL-17RA regulates, by recruitment of non-parenchymal cell, the expression of IL-6, which in turn triggers the proliferation of residual hepatocytes. Our data indicate an important role played by IL-17RA in liver proliferation via IL-6.

Enterococcus species, natural inhabitants of the human gut, have become major causes of life-threatening bloodstream infections (BSIs) and the third most frequent cause of hospital-acquired bacteremia. The rise of high-level gentamicin resistance (HLGR) in enterococcal isolates complicates treatment and revives bacteriophage therapy. This study isolated and identified forty E.

Bilio-biliary anastomosis (BBA) is a critical surgical procedure that is performed with the objective of restoring bile duct continuity. This procedure is often required in cases where there has been an injury to the extrahepatic bile ducts or during liver transplantation. Despite advances in surgical techniques, the healing of BBA remains a significant challenge, with complications such as stricture formation and leakage affecting patient outcomes.

Cirrhosis is a major cause of morbidity and mortality; however, there are no approved therapies except orthotopic liver transplantation. Preclinical studies showed that bone-marrow-derived macrophage injections reduce inflammation, resolve fibrosis and stimulate liver regeneration. In a multicenter, open-label, parallel-group, phase 2 randomized controlled trial ( ISRCTN10368050 ) in n = 51 adult patients with compensated cirrhosis and Model for End-Stage Liver Disease (MELD) score ≥10 and ≤17, we evaluated the efficacy of autologous monocyte-derived macrophage therapy (n = 27) compared to standard medical care (n = 24).

Background: Chemotherapy drugs may lead to hepatic injury, which is considered one of the limitations of these drugs.
Objectives: The aim of this study was to evaluate the effect of quercetin (QUE) on M1/M2 macrophage polarization and hepatoprotective effect in cyclophosphamide (CTX)-induced liver toxicity.
Methods: Twenty-four mice were divided into four groups (Control, QUE, CTX, CTX + QUE).
