In addition, hAAT completely suppressed macrophage inflammatory protein-2 (MIP-2)/monocyte chemotactic protein-1 (MCP-1) gene expression in lung [39]. Human AAT also enhanced anti-inflammatory cytokine IL-10 production from monocytes [15]. As a consequence of interfering with the cytokine/chemokine network, hAAT may also inhibit polymorphonuclear leukocyte (PMN) invasion into the joint. Churg et al. demonstrated that hAAT inhibited silica-induced PMN influx into the lung and partially suppressed nuclear transcription factor B (NF-B) translocation and increased inhibitor of NF-B (I-B) levels in a mouse model of acute PMN mediated inflammation [39]. Thus, it is possible
