Dendritic cell-specific ICAM-3 grabbing non-integrin (DC-SIGN or CD299) and DC-SIGN related protein (DC-SIGNR, DC-SIGN2, L-SIGN or CD209L) are type II membrane proteins that are mannose-specific calcium-dependent (C-type) lectins. The two proteins share 77% amino acid identity. DC-SIGN mediates interactions between dendritic cells (DCs) and T cells. Both DC-SIGN and DC-SIGNR have been shown to bind HIV, hepatitis C glycoproteins, Ebola virus glycoproteins and the cellular adhesion protein ICAM-3 (1‑4). DC-SIGN and DC-SIGNR appear to selectively recognize and bind viral proteins containing a large portion of high-mannose oligosaccharides (5). Though DC-SIGN and DC-SIGNR are found on the same chromosome, they are not expressed in the same tissue. DC-SIGN is expressed solely on Dendritic cells while DC-SIGNR is found on endothelial cells in the liver and lymph node sinuses and in a significant portion of capillary endothelial cells in term placenta (1, 4).

Human DC-SIGNR/CD299 and DC-SIGN transfected 3T3 mouse embryonic fibroblast cell line were stained with Mouse Anti-Human DC-SIGNR/CD299 Monoclonal Antibody (Catalog # MAB162, filled histograms) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0102B).
Detection of Human DC-SIGNR/CD299/CLEC4M by Immunocytochemistry/Immunofluorescence
In situ localization of Ptx3-LECs and transition between Ptx3-LECs and Marco-LECs in human LNs. (A) Expression of CD36/Cd36 in LN LEC subsets of human and mouse. Dots indicate mean log-normalized transcript count. (B–D) Identification of CD36high Ptx3-LECs in human head and neck LNs by immunostaining. (B,C) Immunofluorescence of PROX-1, MARCO and CD36 (B), or PROX-1, LYVE-1 and CLEC4M (C). Zoomed-in images (inset marked by blue dotted lines) in (B) and (C) demonstrate CD36high LYVE-1+ paracortical sinuses (filled arrowhead). Scale bars = 500 μm (left panels) and 100 μm (right panel inset). (D) CD36high LYVE-1+ Ptx3-LECs (filled arrowhead) can be seen associated with MARCO+ CLEC4M+ Marco-LECs (empty arrowhead) in human LNs. Scale bars = 100 μm. CD36high Ptx3-LECs were detected in four out of seven human LNs. Images are representative of four biological replicates.
