Article Abstract

To verify the serological response mounted against antigenic peptides from HERV-Wenv protein, we analyzed 80 multiple sclerosis (MS) serum samples, 27 of which were re-analyzed after a 6-month follow-up IFN-β therapy, and 73 healthy controls. Indirect ELISAs were carried out to detect antibodies specific for all the synthetic peptides derived from HERV-Wenv. Two antigenic peptides, HERV-Wenv93-108 (31.25%, p<0.0001) and HERV-Wenv248-262 (15%, p=0.02), were highly recognized by MS patients' antibodies when compared to healthy subjects. Moreover, antibody titer against these two peptides slightly decreased after six months of IFN-β-based therapy.
