Figure 2

(a, b) Sections of synovial tissue of a patient with rheumatoid arthritis. The sections were stained for demonstration of TNF-alpha (a) and for TNF-alpha after preabsorption with TNF-alpha antigen (b). Inflammatory cells show specific immunoreaction in (a) (arrows). There are no specific immunoreactions in these in (b) (arrows). The inflammatory cells had in parallel sections been identified via staining for routine morphology (htx eosin).
