Summary: Tumor cells undergo uncontrolled proliferation driven by enhanced anabolic metabolism including glycolysis and glutaminolysis. Targeting these pathways to inhibit cancer growth is a strategy for cancer treatment. Critically, however, tumor-r

BackgroundEnterobacterales are often responsible for urinary tract infection (UTI) in kidney transplant recipients. Among these, Escherichia coli or Klebsiella species producing extended-spectrum beta-lactamase (ESBL) are emerging. However, there are

The efficacy of T-cell-based cancer immunotherapies can be compromised by T cell exhaustion. Here the authors develop a human ex vivo exhaustion model and, based on a CRISPR-Cas9 screen, identify SNX9 as a regulator of T cell exhaustion, showing that

Summary: CD28 provides the prototypical costimulatory signal required for productive T-cell activation. Known molecular consequences of CD28 costimulation are mostly based on studies of protein signaling molecules. The microRNA cluster miR-17∼92 is
