  • Bile metabolite of gut microbes boosts immune cells

    A new study has discovered a novel means by which bacterial colonies in the small intestine support the generation of regulatory T cells--immune cells that suppress autoimmune reactions and inflammation.

  • Trivalent CAR T Cells a Triple Threat to Leukemia Cells

    A trident can make spearfishing more of a sure thing. Similarly, a T cell engineered to brandish three prongs—chimeric antigen receptors (CARs)—can kill cancer cells more efficaciously than single-pronged or even double-pronged CAR T cells, let alone ordinary, unmodified T cel…

  • Diagnostics, meet CRISPR

    A new diagnostic test to quickly and easily monitor kidney transplant patients for infection and rejection relies on a simple urine sample and a powerful partner: the gene-editing technology CRISPR.

  • Genetic Mechanism behind Inflammatory Bowel Disease Discovered

    Scientists at Children's Hospital of Philadelphia (CHOP) say they have pinpointed a genetic variation responsible for driving the development of inflammatory bowel disease (IBD). The genetic pathway associated with this variation is involved in other immune disorders, suggesting t…

  • Researchers Move Closer to Industrial Production of Heparin in Cell Culture

    Scientists at the University of California-San Diego say they have moved one step closer to the ability to make heparin in cultured cells. Heparin is a potent anti-coagulant and the most prescribed drug in hospitals, yet cell-culture-based production of heparin is currently not po…

  • Grafted Stems Cells Repair Stroke Damaged Brains in Rats

    Repairing neurological damage has never been an easy task for scientists and physicians but remains the ultimate goal for much of the research in neuroscience. For instance, transplanting neuronal stem cells into damaged or diseased areas of the brain has been touted as a potentia…

  • New Tools for Studying Genetic Variation in Cancer

    In cancer genomics, researchers are "really missing a lot of things by not looking for them in the right way," says Shruti Iyer, a PhD candidate in the Genetics Program at Stony Brook University. In a recent talk in New York*, Iyer, who is pursuing her doctoral research in Dr. W. …

  • CRISPR-Cas9 Defies PAM Restrictions, Edits Genomic Regions Once Out of Bounds

    Unless you a re a bacterium, you may want to go PAMless. PAMs, or protospacer adjacent motifs, are what bacteria use to distinguish their own DNA from invasive viral DNA. That is, PAMs help spare bacterial DNA from being cut apart by the bacterial immune system known as CRISPR . P…

  • Breakthrough in unlocking genetic potential of ocean microbes

    Researchers have made a major breakthrough in developing gene-editing tools to improve our understanding of one of the most important ocean microbes on the planet. The international project unlocks the potential of the largest untapped genetic resource for the development of natur…
