Antigen induced arthritis in beige (Chediak-Higashi) mice.
Mice with the beige mutation, which are known to be deficient for leucocyte elastase and cathepsin G, were used to investigate the role of neutral proteases in a model for antigen induced arthritis. Surprisingly, it was shown that in this model of arthritis, using methylated bovine serum albumin as an antigen, C57/black/6 'beige' mice (deficient for leucocyte neutral proteases) developed a more...
متن کاملExperimental arthritis in C57black/6 normal and beige (Chediak-Higashi) mice: in vivo and in vitro observations on cartilage degradation.
Mice with the beige mutation are known to be deficient for polymorphonuclear leucocyte (PMN) elastase and cathepsin G and can therefore be used as a model for protease dependence of tissue destruction in inflammatory conditions. The in vitro and in vivo effect of PMN activation on cartilage damage in C57black/6 normal and beige mice was measured. In vitro it was found that stimulation of normal...
متن کاملBeige rat: a new animal model of Chediak-Higashi syndrome.
Although Chediak-Higashi syndrome (CHS) has been found in various mammalian species, it has not been described in rats. Since giant granules characterizing CHS are easily recognizable in mast cells of beige (CHS) mice, we screened mast-cell granules in the auricle of some mutant rats, of which coat color was diluted by mutation. Giant granules of mast cells were found in a mutant trait that occ...
متن کاملNeurobeachin: A protein kinase A-anchoring, beige/Chediak-higashi protein homolog implicated in neuronal membrane traffic.
We describe the identification and initial characterization of neurobeachin, a neuron-specific multidomain protein of 327 kDa with a high-affinity binding site (K(d), 10 nm) for the type II regulatory subunit of protein kinase A (PKA RII). Neurobeachin is peripherally associated with pleomorphic tubulovesicular endomembranes near the trans sides of Golgi stacks and throughout the cell body and ...
متن کاملSpecific protease deficiency in polymorphonuclear leukocytes of Chediak- Higashi syndrome and beige mice
Peripheral blood leukocytes of three patients with Chédiak-Higashi syndrome (CHS) contained very low or undetectable levels of elastase, the major neutral protease in these cells. Likewise, peritoneal exudate leukocytes of beige mice (the murine counterpart of CHS) contained correspondingly reduced levels of their major neutral protease, a serine enzyme of mol wt 27,000. The elastase deficiency...
