Abstract

CXCL16 acts as a scavenger receptor for oxLDL in its membrane-bound form and induces migration of activated T cells in its soluble form. Due to these properties, CXCL16 has been suggested to play a role in both atherosclerosis and rheumatoid arthritis (RA). Our aim was to evaluate the contribution of soluble CXCL16 to the scavenging of oxLDL and its potential as a marker for cardiovascular disease (CVD) in patients with RA. We found that circulating CXCL16 was not correlated with plasma oxLDL or ApoB and was not related to the presence of CVD in RA patients. Moreover, CXCL16 did not bind and scavenge oxLDL in an in vitro setting. These data suggest that binding of oxLDL by soluble CXCL16 does not play a role in atherosclerosis and, although confirmation in larger studies is needed, that circulating CXCL16 is not related to the presence of CVD in patients with RA.
