Influence of human allergic encephalitogenic peptide on platelet aggregation in multiple sclerosis

After addition of encephalitogenic peptide to the blood of multiple sclerosis patients a factor X with platelet aggregation activating property could be demonstrated in the supernatant serum. Factor X was able to induce a platelet aggregation or to enhance an ADP-induced platelet aggregation. These findings suggest an explanation for the well-known platelet alterations found in multiple sclerosis.
