Abstract

The aim of the study was to evaluate the type-1 immune response by analyzing T-bet expression in circulating T and B cells in Primary Progressive (PP) and Secondary Progressive (SP) Multiple Sclerosis (MS) patients. We found higher percentages of circulating CD4 +T-bet + and CD8 +T-bet + T cells in SPMS and PPMS than in remitting-relapsing MS patients and controls. Moreover, in SPMS, we observed a positive correlation between the percentages of circulating CD4 +T-bet + or CD8 +T-bet + T cells and disease severity. The increased percentages of Th1 and Tc1 cells suggest that MS progressive forms, unlike RRMS, are characterized by a permanent peripheral type-1 immune activation.
