Lymphatic-derived oxysterols promote anti-tumor immunity and response to immunotherapy in melanoma by Mengzhu Sun, Laure Garnier, Romane Chevalier, Martin Roumain, Chen Wang, Julien Angelillo, Julien Montorfani, Robert Pick, Dale Brighouse, Nadine Fournier, David Tarussio, Stéphanie Tissot, Jean-Marc Lobaccaro, Tatiana V. Petrova, Camilla Jandus, Daniel E. Speiser, Manfred Kopf, Caroline Pot, Christoph Scheiermann, Krisztian Homicsko, Giulio G. Muccioli, Abhishek D. Garg, Stéphanie Hugues

“…We show in a lymphangiogenic murine melanoma that lymphatic endothelial cells (LECs) upregulate the enzyme Ch25h, which catalyzes the formation of 25-hydroxycholesterol (25-HC) from cholesterol and plays important roles in lipid metabolism, gene regulation, and immune activation. We identify a role for LECs as a source of extracellular 25-HC in tumors inhibiting PPAR-γ in intra-tumoral macrophages and monocytes, preventing their immunosuppressive function and instead promoting their conversion into proinflammatory myeloid cells that support effector T cell functions. …”

Conjugation of LasR Quorum-Sensing Inhibitors with Ciprofloxacin Decreases the Antibiotic Tolerance of P. aeruginosa Clinical Strains by Daria Bortolotti, Claudio Trapella, Alessandra Bragonzi, Paolo Marchetti, Vinicio Zanirato, Andrea Alogna, Valentina Gentili, Carlo Cervellati, Giuseppe Valacchi, Mariangela Sicolo, Giulia Turrin, Anna Fantinati, Dario Di Luca, Roberta Rizzo

“…During infection, P. aeruginosa produces a well-organized bacterial structure, called biofilm, activating the quorum-sensing (QS) signaling, a mechanism of gene regulation. In this work, we synthesized already known QS inhibitors (QSi) designed on the scaffold of the N-(3-oxododecanoyl) homoserine lactone (3O-C12-HSL) QS molecule and conjugated them with ciprofloxacin to inhibit P. aeruginosa biofilm formation and increase the antibiotic susceptibility of clinical strains. …”

“…Here we show a human CAR agonist/PXR antagonist, MI-883, which effectively regulates genes related to xenobiotic metabolism and cholesterol/bile acid homeostasis by leveraging CAR and PXR interactions in gene regulation. Through comprehensive analyses utilizing lipidomics, bile acid metabolomics, and transcriptomics in humanized PXR-CAR-CYP3A4/3A7 mice fed high-fat and high-cholesterol diets, we demonstrate that MI-883 significantly reduces plasma cholesterol levels and enhances fecal bile acid excretion. …”
