Megjegyzések:	The chemokine, epithelial neutrophil-activating peptide-78 (ENA-78), is a potent neutrophil chemotaxin whose expression is increased in inflamed synovial tissue and fluid in human rheumatoid arthritis compared with osteoarthritis. Since ENA-78 has been implicated in the pathogenesis of RA, we examined the expression of an ENA-78-like protein during the development of rat adjuvant-induced arthritis (AIA). Using an ELISA assay, we found increased levels of antigenic ENA-78-like protein in the sera of AIA animals compared with control normal animals by day 7 postadjuvant injection. ENA-78-like protein levels continued to increase as AIA developed. ENA-78-like protein levels in joint homogenates were increased in AIA animals later in the development of the disease, by day 18 during maximal arthritis, compared with control animals. Expression of ENA-78-like protein in both the AIA serum and joint correlated with the progression of inflammation of the joints. Anti-human ENA-78 administered before disease onset modified the severity of AIA, while administration of anti-ENA-78 after clinical onset of AIA did not modify the disease. These data support a role for an ENA-78-like protein as an important chemokine in the progression and maintenance of AIA.

Megjegyzések:	To examine cytokine and chemokine production during the evolution of rat adjuvant-induced arthritis (AIA), a model of rheumatoid arthritis. METHODS: Clinical and laboratory assessment of the course of AIA was performed over a 47-day period. Levels of the cytokines tumor necrosis factor a (TNFalpha), interleukin-1beta (IL-1beta), and IL-6, as well as levels of the chemokines macrophage inflammatory protein 1alpha (MIP-1alpha) and JE, the murine homolog of monocyte chemoattractant protein 1, were determined by enzyme-linked immunosorbent assay in the sera and joints of AIA and control rats. Synovia from AIA rats were (immuno)histochemically analyzed. Results of cytokine and chemokine measurements were correlated with clinical and laboratory markers of inflammation and histology. RESULTS: Early (before day 14 post adjuvant injection) and later phases of AIA could be distinguished. Cytokine and chemokine production was increased in AIA versus control rats. The production of TNFalpha, IL-1beta, MIP-1alpha, and, as determined earlier, epithelial neutrophil-activating peptide 78-like protein was abundant prior to and during the course of AIA, while that of IL-6 and JE was elevated in the late phase of AIA. Cytokine and chemokine levels were correlated with the clinical symptoms of arthritis and blood neutrophil counts. Joint levels of IL-1beta showed correlation with synovial lining proliferation and neutrophil ingress into AIA synovium. CONCLUSION: Cytokines and chemokines are involved in the clinical, laboratory, and histologic changes underlying AIA. The production of these mediators may be temporally and spatially regulated. These findings may be important for the optimal timing of cytokine and chemokine targeting.
