Dummer R, Mittelman A, Fanizzi FP, Lucchese G, Willers J, Kanduc D: Non-self-discrimination as a driving concept in the identification of an immunodominant HMW-MAA epitopic peptide sequence by autoantibodies from melanoma cancer patients. Int J Cancer. 2004 Sep 20;111(5):720-6.
We analyzed the sera of patients with melanoma to define the human humoral autoantibody profile towards HMW-MAA. Computational proteome scanning using the non-self-discrimination principle as a guide led to the individuation of the low-similarity HMW-MAA781-789RATVWMLRL peptide fragment as an immunodominant B-cell epitope. Linear B-cell determinant individuation was experimentally validated by dot blot immunoassay and NMR spectroscopy analysis. Regulation of physiologic self-reactivity by the non-self-discrimination principle is discussed. |
