Proteome-Wide Epstein-BarrVirus Analysis of Peptide Sharing with Human Systemic Lupus Erythematosus Autoantigens

Summary

Background:

Although cross-reactions between Epstein-Barr virus (EBV) and human systemic lupus erythematosus (SLE) autoantigens occur, a complete analysis of the potential EBV peptide cross-reactome has not been performed.

Objectives:

To analyze the whole EBV proteome searching for peptides common to SLE-related proteins and endowed with an immunological potential.

Methods

: Fifty-one SLE-related proteins were analyzed for hexapeptide sharing with EBV proteome using publicly available databases.

Results

: An extremely high number of hexapeptides are shared between 34 human SLE autoantigens and EBV proteins. The peptide sharing mostly occurs with complement components C4 and Interleukin-10 (IL-10).

Conclusion

: This study thoroughly describes the EBV vs. SLE autoantigens peptide overlap and powerfully supports cross-reactivity as a major mechanism in EBV-associated SLE etiopathogenesis.
