GERDSZYMULA and others38 hypothesized that molecular mimicry of bacterial peptides from oral commensals (digesting Prevotella lytoltica, codigenet sputum, codigenet flavus) in SS patients could induce an immune response by activating SSA/Ro60 reactive T cells, which may be a potential trigger for autoimmunity in SS patients. Here, RO60 is linked to synovial sarcoma.
