Abstract

The C-type lectin dendritic cell-specific ICAM 3-grabbing nonintegrin (DC-SIGN)/CD209 efficiently binds several pathogens, including HIV-1. DC-SIGN is expressed on monocyte-derived DCs in culture, and importantly, it is able to sequester HIV-1 within cells and facilitate transmission of virus to CD4+ T cells. To investigate DC-SIGN function, we have generated new mAbs. We report in this study that these and prior anti-DC-SIGN mAbs primarily label macrophages in the medullary sinuses of noninflamed human lymph node. In contrast, expression is not detected on most DCs in the T cell area, except for occasional cells. We also noted that IL-4 alone can induce expression of DC-SIGN in CD14+ monocytes and circulating blood DCs. However, blockade of DC-SIGN with Abs and DC-SIGN small interfering RNA did not result in a major reduction in the capacity of these DCs to transfer HIV to T cells, confirming significant DC-SIGN-independent mechanisms. The blocking approaches did reduce HIV-1 transmission by DC-SIGN-transfected cells by >90%. DC-SIGN blockade also did not reduce the ability of DCs to stimulate T cell proliferation in the MLR. These results indicate that DC-SIGN has the potential to contribute to macrophage function in normal human lymph node, and that DCs do not require DC-SIGN to transmit HIV or to initiate T cell responses.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • There exists a DC-SIGN-independent mechanism of trans-infection with HIV-1 viral particles.

    “However, the results of other studies indicate the existence of a DC-SIGN-independent mechanism of trans-infection with HIV-1 viral particles [81,82,83,84].”

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.
