Abstract

The escape of malignant cells from the immune response against the tumor may result from a defective differentiation or function of professional antigen-presenting cells (APC), ie, dendritic cells (DC). To test this hypothesis, the effect of human renal cell carcinoma cell lines (RCC) on the development of DC from CD34(+) progenitors was investigated in vitro. RCC cell lines were found to release soluble factors that inhibit the differentiation of CD34(+) cells into DC and trigger their commitment towards monocytic cells (CD14(+)CD64(+)CD1a-CD86(-)CD80(-)HLA-D Rlow) with a potent phagocytic capacity but lacking APC function. RCC CM were found to act on the two distinct subpopulations emerging in the culture at day 6 ([CD14(+)CD1a-] and [CD14(-)CD1a+]) by inhibiting the differentiation into DC of [CD14(+)CD1a-] precursors and blocking the acquisition of APC function of the [CD14(-)CD1a+] derived DC. Interleukin-6 (IL-6) and macrophage colony-stimulating factor (M-CSF) were found to be responsible for this phenomenon: antibodies against IL-6 and M-CSF abrogated the inhibitory effects of RCC CM; and recombinant IL-6 and/or M-CSF inhibited the differentiation of DC similarly to RCC CM. The inhibition of DC differentiation by RCC CM was preceeded by an induction of M-CSF receptor (M-CSFR; CD115) and a loss of granulocyte-macrophage colony-stimulating factor receptor (GM-CSFR; CD116) expression at the surface of CD34(+) cells, two phenomenon reversed by anti-IL-6/IL-6R and anti-M-C…

Recomputing p-values needs the paper’s full text.

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?

  • CSF-2 in isolation also promotes differentiation of monocytes into a dendritic cell lineage, which maintains a phagocytic phenotype (CD68 immunopositive).

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.
