CD163 and endothelial dysfunction: In this study, we analyzed sTWEAK and sCD163 plasma levels and other known markers of inflammation (high-sensitivity C-reactive protein [hsCRP], interleukin 6 [IL-6] and soluble tumor necrosis alpha receptor II [sTNFRII]), endothelial dysfunction (soluble vascular cell adhesion molecule 1 [sVCAM-1] and asymmetric dimethylarginine [ADMA]) and thrombotic activity (D-dimer) in healthy subjects and patients with HIV.
