PEPTIDE FRAGMENTS FROM HUMAN CYTOCHROME P450 IID6, PEPTIDE ANTI-FRAGMENT ANTIBODIES AND THEIR APPLICATIONS IN THE DIAGNOSIS OF AUTOIMMUNE HEPATITIS.

摘要

Human P450 IID6 cytochrome-derived peptide fragments, anti peptide anti fragment antibodies and applications thereof in the diagnosis of autoimmune hepatitis and more especially in the differential diagnosis between autoimmune hepatitis and other chronc viral forms of hepatitis, such as hepatitis C or B. Said human P450 cytochrome peptide fragment contains at least one P450 IID6 cytochrome immunodominant epitope and consists of an amino acid sequence comprising from 3 to 70 amino acids. Said peptide binds specifically with anti-LKM auto-antibodies produced in autoimmune hepatitis.
