Mice were classified as arthritic upon positive confirmation by histological analysis. a+Ab denotes group injected with arthritogenic clone B2 and then treated with anti-hTNF antibody 2 weeks after injection. b 'Lung' refers to a population of hTNF-secreting lung fibroblasts derived from hTNF/TAg double transgenic mice. hTNF, human tumor necrosis factor; RAG, recombinant activating gene; TAg, large tumor antigen; wt, wild-type.
