Notably, B-cell Neu1 levels are strong predictors of remission as defined by two stringent remission criteria for rheumatoid arthritis (RA) [9,10,11], whereas B-cell ST6Gal1 levels are associated only with remission status, as defined by the 2005 modified American Rheumatism Association (ARA) criteria [11]. This evidence concerns the gene ST6GAL1 and rheumatoid arthritis.
