    Summary:Tumor-specific cytotoxic T cells unleashed by the blockade of immune checkpoints have to overcome a hostile tumor microenvironment (TME). They start from very small numbers of T cells with tumor antigen specificity and, despite expansion, likely remain at a numerical disadvantage to the tumor cells they target. To overcome these obstacles, we propose that T cells need to change the TME to…

    Profiling of circulating immune cells provides valuable insight to the pathophysiology of acute rejection in organ transplantation. Herein we characterized the peripheral blood mononuclear cells in simultaneous kidney-pancreas transplant recipients. We conducted a retrospective analysis in a biopsy-matched cohort (n = 67) and compared patients with biopsy proven acute rejection (BPAR; 41%) to…
