摘要

Antigen-presenting cells participate and are implicated in the pathogenesis of multiple sclerosis. In our study we assessed the frequency of plasmacytoid (pDC) and myeloid (mDC) dendritic cells and the classical, intermediate and non-classical monocytes subsets, as well as their phenotypic and functional profile. We evaluated peripheral blood from relapsing-remitting patients treated with IFN-beta in remission and relapse phases and from healthy subjects. In remission, we observed a decrease of mDC/pDC ratio and a return to normal values in relapse. In both phases the frequency of non-classical monocytes decreases. Concerning the phenotypic characterization, an increased HLA-DR expression was observed in remission and a decrease in relapse, revealing alterations in monocytes and dendritic cells homeostasis.
