The soluble form of CD146 has been reported to be present in various inflammatory diseases and displays pro-inflammatory properties. However, little is known about sCD146 in multiple sclerosis (MS). Here we show that sCD146 is significantly elevated in the cerebrospinal fluid of patients with active MS compared with that of inactive MS or patients with non-demyelinating diseases. Moreover, abnormally increased sCD146 in the CSF of active MS patients correlated with albumin quotient, MBP antibody and MOO antibody from both CSF and sera. Importantly, the level of CSF sCD146 is correlated with levels of inflammatory factors, such as TNF alpha, IFN gamma, IL-2, and IL-17A in the CSF. We also found that CSF sCD146 might originate from membrane-bound CD146 on inflamed blood-brain barrier (BBB) endothelial cells. In addition, sCD146 promotes leukocyte transmigration in vitro, at least in part by stimulating the expression of ICAM-1 and VCAM-1 on endothelial cells. Our findings suggest that CSF levels of sCD146 may provide a potential marker for monitoring disease activity in MS patients. (C) 2013 IBRO. Published by Elsevier Ltd. All rights reserved.
