Abstract

DC-SIGN is a C-type lectin, highly expressed on the surface ofimmature dendritic cells (DCs), that mediates efficient infection of Tcells in trans by its ability to bind HIV-1, HIV-2, and SIV. Inaddition, the ability of DC-SIGN to bind adhesion molecules on surfacesof naïve T cells and endothelium also suggests its involvementin T-cell activation and DC trafficking. To gain further insights intothe range of expression and potential functions of DC-SIGN, weperformed a detailed analysis of DC-SIGN expression in adult and fetaltissues and also analyzed its regulated expression on cultured DCs andmacrophages. First, we show that DC-SIGN expression is restricted tosubsets of immature DCs in tissues and on specialized macrophages inthe placenta and lung. There were no overt differences between DC-SIGNexpression in adult and fetal tissues except that DC-SIGN expression inalveolar macrophages was only present after birth. Similarly, intissues, DC-SIGN was observed primarily on immature (CD83-negative)DCs. Secondly, in the peripheral blood, we found expression of DC-SIGNon a small subset of BDCA-2+ plasmacytoid DC precursors (pDC2),concordant with our finding of large numbers of DC-SIGN-positive cellsin allergic nasal polyps (previously shown to be infiltrated by DC2). Triple-label confocal microscopy indicated that DC-SIGN was colocalizedwith BDCA-2 and CD123 on DCs in nasal polyp tissue. Consistent withthis finding is our observation that DC-SIGN can be up-regulated onmonocyte-derived macrophages upon exposure to the Th2 cytokine, IL-13. In summary, our data demonstrate the relevant populations of DC andmacrophages that express DC-SIGN in vivo where it may impact theefficiency of virus infection and indicate that DC-SIGN expression maybe involved in the Th2 axis of immunity.

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.
