CD40 stimulation obviates innate sensors and drives T cell immunity in cancer

Abstract

Cancer immunotherapies are more effective in tumors with robust T cell infiltrates, but mechanisms to convert T cell-devoid tumors with active immunosuppression to those capable of recruiting T cells remain incompletely understood. Here, using genetically engineered mouse models of pancreatic ductal adenocarcinoma (PDA), we demonstrate that a single dose of agonistic CD40 antibody with chemotherapy rendered PDA susceptible to T cell-dependent destruction and potentiated durable remissions. CD40 stimulation caused a clonal expansion of T cells in the tumor, but the addition of chemotherapy optimized myeloid activation and T cell function. Although recent data highlight the requirement for innate sensors in cancer immunity, these canonical pathways-including TLRs, inflammasome, and type I interferon/STING-played no role in mediating the efficacy of CD40 and chemotherapy. Thus, CD40 functions as a non-redundant mechanism to convert the tumor microenvironment immunologically. Our data provide a rationale for a newly initiated clinical trial of CD40 and chemotherapy in PDA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
