Background: The relevance of human leukocyte antigen (HLA)-G in dimeric form in multiple sclerosis (MS) is still unknown. Objective: To investigate the contribution of cerebrospinal fluid (CSF) HLA-G dimers in MS pathogenesis. Methods: CSF amounts of 78-kDa HLA-G dimers were measured by western blot analysis in 80 MS relapsing-remitting MS (RRMS) patients and in 81 inflammatory and 70 non-inflammatory controls. Results: CSF amounts of 78kDa HLA-G dimers were more frequent in RRMS than in inflammatory (p<0.01) and non-inflammatory controls (p<0.001) and in magnetic resonance imaging (MRI) inactive than in MRI active RRMS (p<0.00001). Conclusion: Our findings suggest that HLA-G dimers may be implicated in termination of inflammatory response occurring in MS.

Abstract
Background: The relevance of human leukocyte antigen (HLA)-G in dimeric form in multiple sclerosis (MS) is still unknown. Objective: To investigate the contribution of cerebrospinal fluid (CSF) HLA-G dimers in MS pathogenesis. Methods: CSF amounts of 78-kDa HLA-G dimers were measured by western blot analysis in 80 MS relapsing-remitting MS (RRMS) patients and in 81 inflammatory and 70 non-inflammatory controls. Results: CSF amounts of 78kDa HLA-G dimers were more frequent in RRMS than in inflammatory (p<0.01) and non-inflammatory controls (p<0.001) and in magnetic resonance imaging (MRI) inactive than in MRI active RRMS (p<0.00001). Conclusion: Our findings suggest that HLA-G dimers may be implicated in termination of inflammatory response occurring in MS.
