Fibrosis is involved in 30?45% of deaths in the U.S. The disease may involve a runaway positive feedback loop between fibroblasts and monocyte-derived fibrocytes. The signals from fibrocytes to fibroblasts include inflammatory cytokines such as TNF-?, but the signals from TNF-?-stimulated fibroblasts to fibrocytes are unknown. We find that one of these signals is the protein lumican, and show that lumican levels are increased in fibrotic lesions. The identification of lumican as a signal in fibrotic tissues that promotes fibrocyte differentiation represents a major advance in our understanding of the regulation of the innate immune system, supports the positive feedback loop model of fibrosis, and indicates that lumican-inhibiting drugs may be beneficial in regulating fibrosis.
