Lung fibrosis development utilizes alveolar macrophages, with mechanisms that are incompletely understood. Here, we fate map connective tissue during mouse lung fibrosis and observe disassembly and transfer of connective tissue macromolecules from pleuro-alveolar junctions (PAJs) into deep lung tissue, to activate fibroblasts and fibrosis. Disassembly and transfer of PAJ macromolecules into deep lung tissue occurs by alveolar macrophages, activating cysteine-type proteolysis on pleural mesothelium.

Article Synopsis
  • Despite improvements in targeted therapy for Acute Myeloid Leukemia (AML), the prognosis remains poor, particularly for patients with relapsed or refractory disease.
  • Allogeneic hematopoietic stem cell transplantation (alloSCT) is the main curative option for high-risk patients, but the best conditioning approach is still uncertain for those who are chemotherapy-refractory.
  • A study on seven AML patients who received CXCR4-directed endoradiotherapy (ERT) combined with total body irradiation and chemotherapy prior to alloSCT showed promising outcomes, with 6 out of 7 patients achieving response and successful engraftment, offering insights into a potentially effective treatment strategy for advanced cases.

From the pioneering moment in 1987 when the insulinotropic effect of glucagon-like peptide 1 (GLP-1) was first demonstrated in humans, to today's pharmaceutical gold rush for GLP-1-based treatments of obesity, the journey of GLP-1 pharmacology has been nothing short of extraordinary. The sequential conceptual developments of long-acting GLP-1 receptor (GLP-1R) mono-agonists, GLP-1R/glucose-dependent insulinotropic polypeptide receptor (GIPR) dual-agonists, and GLP-1R/GIPR/glucagon receptor (GcgR) triple agonists, have led to profound body weight-lowering capacities, with benefits that extend past obesity and towards obesity-associated diseases. The GLP-1R/GIPR dual-agonist tirzepatide has demonstrated a remarkable 23% body weight reduction in individuals with obesity over 72 weeks, eclipsing the average result achieved by certain types of bariatric surgery.
