    CPX-351 Exploits the Gut Microbiota to Promote Mucosal Barrier Function, Colonization Resistance, and Immune Homeostasis

    Investigators evaluated the impact of CPX-351 and “7+3” combination on mucosal barrier function, gut microbial composition and function, and antifungal colonization resistance in preclinical models of intestinal damage in vitro and in vivo and fecal microbiota transplantation.

    Non-Apoptotic FAS Signaling Controls mTOR Activation and Extrafollicular Maturation in Human B Cells

    Modeling initial T-dependent B cell activation with CD40L en vitro, researchers showed that FAS competent cells with transient FAS ligation showed specifically decreased mTOR axis activation without apoptosis.

    Human Uterine Natural Killer Cells Regulate Differentiation of Extravillous Trophoblast Early in Pregnancy

    By locating potential interaction axes between trophoblast and uterine NK (uNK) cells using single-cell transcriptomics and in vitro modeling of these interactions in organoids, investigators identified a uNK cell-derived cytokine signal that promoted trophoblast differentiation.

    C-C Chemokine Receptor Type 7 (CCR7) Regulates Hepatic CD8+ T Cell Homeostasis and Response to Acute Liver Injury

    Researchers analyzed liver tissue from two independent patient cohorts with acute liver failure and identified hepatic T cell infiltration as a prominent feature in human acute liver failure.

    Tumor Resistance to Anti-Mesothelin CAR-T Cells Caused by Binding to Shed Mesothelin Is Overcome by Targeting a Juxtamembrane Epitope

    Scientists developed an antibody (15B6) that bound next to the membrane at the protease-sensitive region, did not bind to shed mesothelin, and made CAR-T cells that had much higher anti-tumor activity than a CAR-T that bound to shed mesothelin.

    Tumor-Associated Neutrophils Suppress CD8+ T Cell Immunity in Urothelial Bladder Carcinoma through the COX-2/PGE2/IDO1 Axis

    The authors conducted a meta-analysis on the predictive value of neutrophil-lymphocyte ratio in immune checkpoint blockade response and investigated tumor-associated neutrophils’ role in urothelial bladder carcinoma.

    The Role of Graft T Cell Size in Patients Receiving Alemtuzumab Serotherapy for Non-Malignant Disorders: Results of an Institutional Protocol

    Investigators retrospectively analyzed 26 consecutive patients with non-malignant disorders grafted using alemtuzumab serotherapy and capping of graft T cells to a maximum of 600 million/kg.
