Mice lacking matrix metalloproteinase-3 (MMP-3; stromelysin-1) demonstrated significantly less injury than their normal counterparts following the formation of IgG-containing immune complexes in the alveolar wall or in the wall of the peritoneum. Likewise, mice lacking MMP-3 demonstrated less lung injury following intra-tracheal instillation of the chemotactic cytokine macrophage inhibitory protein-2 (MIP-2) than did mice with MMP-3. There was a relationship between tissue injury (evidenced histologically) and accumulation of anti-laminin 111 immunoreactive material in the bronchoalveolar lavage (BAL) or peritoneal lavage (PL) fluid. There was also a relationship between tissue injury and influx of neutrophils into the BAL or PL fluid. Taken together, these data demonstrate an important role for MMP-3 in acute inflammatory tissue injury.

D018345 Mice, Knockout Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

D018925 Chemokines Class of pro-inflammatory cytokines that have the ability to attract and activate leukocytes. They can be divided into at least three structural branches: C; (CHEMOKINES, C); CC; (CHEMOKINES, CC); and CXC; (CHEMOKINES, CXC); according to variations in a shared cysteine motif.
