    Divergent response to radio-immunotherapy is defined by intrinsic features of the tumor microenvironment by Christian Klein, Maria Amann, Jacob Gadwa, Laurel B Darragh, Miles Piper, Diemmy Nguyen, Sana D Karam, Michael W Knitz, Justin Yu, Nicholas Olimpo, Sophia Corbo, Jessica I Beynor, Brooke Neupert, Alexander T Nguyen, Chloe Hodgson, Khalid NM Abdelazeem, Anthony Saviola, Laurene Pousse, Ali Bransi, Mudita Pincha

    Published 2025-01-01
    “…However, to date there are few preclinical models that accurately represent these disparate disease scenarios.Methods Using combinatorial radio-immunotherapy consisting of PD-1 blockade, IL2Rβγ biased signaling, and OX40 agonism we were able to generate preclinical tumor models with conflicting responses, where head and neck squamous cell carcinoma (HNSCC) models respond and pancreatic ductal adenocarcinoma (PDAC) progresses.Results By modeling these disparate states, we find that regulatory T cells (Tregs) are expanded in PDAC tumors undergoing treatment, constraining tumor reactive CD8 T cell activity. …”
