In another article, in cultured patellae from mouse methylated bovine serum albumin induced arthritis, the authors reported high IL-17 protein levels in the supernatants 7 days after the induction of arthritis (while our evaluation was performed 24 days after the induction in our rat AIA model, at the end of the plateau phase) [30]. The gene discussed is IL17A; the disease is arthritic joint disease.
