Abstract

Lymphodepletion with total body irradiation (TBI) increases the efficacy of adoptively transferred tumor-specific CD8(+) T cells by depleting inhibitory lymphocytes and increasing homeostatic cytokine levels. We found that TBI augmented the function of adoptively transferred CD8(+) T cells in mice genetically deficient in all lymphocytes, indicating the existence of another TBI mechanism of action. Additional investigation revealed commensal gut microflora in the mesenteric lymph nodes and elevated LPS levels in the sera of irradiated mice. These findings correlated with increased dendritic cell activation and heightened levels of systemic inflammatory cytokines. Reduction of host microflora using antibiotics, neutralization of serum LPS using polymyxin B, or removal of LPS signaling components using mice genetically deficient in CD14 and TLR4 reduced the beneficial effects of TBI on tumor regression. Conversely, administration of microbial ligand-containing serum or ultrapure LPS from irradiated animals to nonirradiated antibody-lymphodepleted mice enhanced CD8(+) T cell activation and improved tumor regression. Administration of ultrapure LPS to irradiated animals further enhanced the number and function of the adoptively transferred cells, leading to long-term cure of mice with large B16F10 tumors and enhanced autoimmune vitiligo. Thus, disruption of the homeostatic balance between the host and microbes can enhance cell-based tumor immunotherapy.

  • The gut microbiome can influence anti-tumor immune responses through innate and adaptive immunity.

    “A number of studies have shown that the gut microbiome may influence anti-tumor immune responses via innate and adaptive immunity (11, 12)”
  • In mouse models, certain gut commensals mediate the efficacy of anticancer therapies including chemotherapy, radiotherapy, adoptive T cell transfer, intratumoral CpG-oligonucleotides, and immune checkpoint inhibitors.

    “In mouse models, certain gut commensals mediate efficacy of anticancer therapies, including chemotherapy, radiotherapy, and immunotherapies such as adoptive T cell transfer, intratumoral CpG-oligonucleotides, and ICIs.”
  • Total-body irradiation improved tumor-specific T cell transfer efficacy by moving bacterial lipopolysaccharide from the gut lumen to secondary lymphoid organs.

    “total-body irradiation, which enhanced the efficacy of tumor-specific T cell transfer through translocation of a bacterial product, the toll-like receptor 4L (TLR4L) lipopolysaccharide, from the intestinal lumen to secondary lymphoid organs (10).”
  • In a murine melanoma adoptive cell therapy model, antibiotics substantially reduced anti-tumor activity.

    “administration of antibiotics significantly abrogated anti-tumor activity in a murine model of adoptive cell therapy for melanoma”

  • Bacterial lipopolysaccharide activates toll-like receptor 4, thus activating immune T cell-mediated response against cancer cells.

    “For example, the widely studied bacterial lipopolysaccharide (LPS), a major component of the outer membrane in gram-negative bacteria, activates the host’s cell surface receptor toll-like receptor 4 (TLR4), belonging to the family of pattern recognition receptors (PRRs), thus activating immune T cell-mediated response against cancer cells [40].”

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.
