Outline of Final Research Achievements |
The component of cryoglobulin was determined in a patient with chronic hepatitis C who underwent antiviral treatment and cleared HCV RNA. Three types of antibodies concentrated in the cryoprecipitate were identified by comparing antibody profiles purified from cryoprecipitate and serum. Two of the three antibodies were autoantibodies and had cross-reactivity with HCV. Several human proteins including PAFAH1B3 were found as candidates for autoantigens. Total RNA extracted from peripheral blood specimens showed a patient-specific antibody sequence repertoire.
