Thirty-nine patients with clinically definite multiple sclerosis (MS) entered the study. Of 28 subjects with a relapsing-remitting course, 19 were classified in acute relapse, 9 in remission; 11 patients had a progressive course without remissions. Furthermore, 6 subjects with inflammatory neurological disease (IND), and 10 with non-inflammatory and non-neoplastic neurological disease (NIND) were investigated. We simultaneously studied cerebrospinal fluid (CSF) and peripheral blood (PB) T-, B- and NK-cell subsets, as defined by following monoclonal antibodies: anti-CD3, -CD4, -CD8, -CD19, -CD16, -HLA-DR and -IL-2-R. We found a significant increase of CD4+ T-cells compared with controls in CSF, with respect to PB, of MS patients, particularly in acute relapse. An increase of HLA-DR+ cell percentages in the CSF than in the PB in all MS groups, especially in attacks of MS but also in remission, was also observed, with a positive correlation between CD4+ T-cell and DR+ cell percentages both in the CSF as well as in the PB of relapsing MS patients. These findings, together with the increase of IL-2-R+ cells in the PB, particularly in relapsing MS, give further support for the presence of a systemic T-cell activation in MS.

Abstract
Thirty-nine patients with clinically definite multiple sclerosis (MS) entered the study. Of 28 subjects with a relapsing-remitting course, 19 were classified in acute relapse, 9 in remission; 11 patients had a progressive course without remissions. Furthermore, 6 subjects with inflammatory neurological disease (IND), and 10 with non-inflammatory and non-neoplastic neurological disease (NIND) were investigated. We simultaneously studied cerebrospinal fluid (CSF) and peripheral blood (PB) T-, B- and NK-cell subsets, as defined by following monoclonal antibodies: anti-CD3, -CD4, -CD8, -CD19, -CD16, -HLA-DR and -IL-2-R. We found a significant increase of CD4+ T-cells compared with controls in CSF, with respect to PB, of MS patients, particularly in acute relapse. An increase of HLA-DR+ cell percentages in the CSF than in the PB in all MS groups, especially in attacks of MS but also in remission, was also observed, with a positive correlation between CD4+ T-cell and DR+ cell percentages both in the CSF as well as in the PB of relapsing MS patients. These findings, together with the increase of IL-2-R+ cells in the PB, particularly in relapsing MS, give further support for the presence of a systemic T-cell activation in MS.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
