LXR agonism promotes macroscopic change in the tumor microenvironment

February 14, 2018

High activity of immunosuppressive cells in the tumor microenvironment (TME) is frequently found in patients who are nonresponders to different forms of immunotherapy, treatments which can demonstrate long-term benefits in the subset of patients who do respond. In a recent paper published in Cell, Tavazoie et al. aimed to elucidate the mechanism by...
