Bilateral upregulation of receptor expression during antigen-induced arthritis. (a) Proportions of DRG neurons with binding of SP–gold in control animals and in different groups of animals with AIA. (b) Proportions of DRG neurons with binding of BK–gold in control animals and in different groups of animals with AIA. Results for DRG neurons from immunized animals without knee injection are shown at 0 days. White bars, contralateral to injected knee; black bars, ipsilateral to injected knee.
