Abstract

TNF plays a dual, still enigmatic role in melanoma, either acting as a cytotoxic cytokine or favoring a tumorigenic inflammatory microenvironment. Herein, the tumor growth of melanoma cell lines expressing major histocompatibility complex class I molecules at high levels (MHC-I(high)) was dramatically impaired in TNF-deficient mice, and this was associated with enhanced tumor-infiltrating CD8(+) T lymphocytes. Immunodepletion of CD8 T cells fully restored melanoma growth in TNF(-/-) mice. Systemic administration of Etanercept inhibited MHC-I(high) melanoma growth in immunocompetent but not in immunodeficient (IFNγ(-/-), nude, or CD8(-/-)) mice. MHC-I(high) melanoma growth was also reduced in mice lacking TNF-R1, but not TNF-R2. TNF(-/-) and TNF-R1(-/-) mice as well as Etanercept-treated WT mice displayed enhanced intratumor content of high endothelial venules surrounded by high CD8(+) T-cell density. Adoptive transfer of activated TNF-R1-deficient or -proficient CD8(+) T cells in CD8-deficient mice bearing B16K1 tumors demonstrated that TNF-R1 deficiency facilitates the accumulation of live CD8(+) T cells into the tumors. Moreover, in vitro experiments indicated that TNF triggered activated CD8(+) T cell death in a TNF-R1-dependent manner, likely limiting the accumulation of tumor-infiltrating CD8(+) T cells in TNF/TNF-R1-proficient animals. Collectively, our observations indicate that TNF-R1-dependent TNF signaling impairs tumor-infiltrating CD8(+) T-cell accumulation and may serve as a putative target to favor CD8(+) T-cell-dependent immune response in melanoma.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Other published reports showed evidence in mouse models that anti-TNF-a enhances the antitumor activity of combined anti-PD-1 and anti-CTLA-4 immunotherapy, reinforces both CD8 T-cell-dependent immunity and anti-PD-1 therapy, by preventing anti-PD-1-induced cell death of tumor infiltrating lymphocytes as well as PD-L1 and Tim-3 expression.

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.
