The expression of adhesion molecules on peripheral blood leucocyte in patients with multiple sclerosis / 中国免疫学杂志

ABSTRACT

Objective:To explore the levels of adhesion molecules in peripheral blood leucocyte from patients with multiple sclerosis(MS) and after intravenous methylprednisolone(MP) treatment.Methods:The positive percentag of intercellular adhesion molecule 1(CD54)?integrin LFA 1 ? subunit(CD18)?very late antigen 4 ??? subunit(CD49d?CD29) and L selectin(CD62L) were determined on lymphocytes and monocytes by flow cytometry from 28 patients with relapsing remitting MS (relapses n=20,remission n=8) and 20 controls.Results:The positive percentage of CD49d?CD29 on lymphocytes and monocytes,CD54 and CD62L on monocytes in relapses MS group were higher than in remission MS group and controls(P0.05).Conclusion:The adhesion molecules expression on peripheral blood leucocyte were elevated in MS patients and it may be suitable to be as a marker of MS activity.
