Autoimmune-Like Mechanism in Heart Failure Enables Preventive Vaccine Therapy.

Background: Heart failure (HF) is strongly associated with inflammation. In pressure overload (PO)-induced HF, cardiac stress triggers adaptive immunity, ablation or inhibition of which blocks disease progression. We hypothesized that PO-HF might fulfill the often-used criteria of autoimmunity: if so, the associated adaptive immune response would be not only necessary but also sufficient to induce HF; it should also be possible to identify self-antigens driving the autoimmune response.

Monitoring circulating tumor DNA liquid biopsy in stage III BRAF-mutant melanoma patients undergoing adjuvant treatment.

Background: The introduction of adjuvant therapies for patients with resected cutaneous melanoma (CM) has increased the need for sensitive biomarkers for risk stratification and disease monitoring. This study aims to investigate the utility of circulating tumor DNA (ctDNA) assessment in predicting and reflecting disease status during adjuvant therapy.

Methods: We enrolled 32 patients with resected BRAF-mutated stage III CM receiving adjuvant targeted therapy or immunotherapy.

Circulating cell-free DNA in liver transplantation: A pre- and post-transplant biomarker of graft dysfunction.

Background: Liver transplantation (LT) is still limited by organ shortage and post-transplant monitoring issues. While machine perfusion techniques allow for improving organ preservation, biomarkers like donor-derived cell-free DNA (dd-cfDNA) and mitochondrial cfDNA (mt-cfDNA) may provide insights into graft injury and viability pre- and post-LT.

Methods: A prospective observational cohort study was conducted on LT recipients (n = 45) to evaluate dd-cfDNA as a biomarker of graft dysfunction during the first 6 months after LT.

Apoliprotein E-mediated ferroptosis controls cellular proliferation in chronic lymphocytic leukemia.

Unraveling vulnerabilities in chronic lymphocytic leukemia (CLL) represents a key approach to understand molecular basis for its indolence and a path toward developing tailored therapeutic approaches. In this study, we found that CLL cells are particularly sensitive to the inhibitory action of abundant serum protein, apolipoprotein E (ApoE). Physiological concentrations of ApoE affect CLL cell viability and inhibit CD40-driven proliferation.
