Abstract：
:Chrysotile asbestos permeabilizes the plasma membrane of rabbit polymorphonuclear leukocytes (PMNs) which is evident from the release of the cytoplasmic enzyme lactate dehydrogenase (LDH) from the cell. When Ca2+ is present in the medium exocytosis is observed, evident from the release of the granule associated enzyme lysozyme which is not liberated in the absence of Ca2+. Asbestos-induced enzyme release is inhibited by polyanions or by removal of positive charges on asbestos, and resembles enzyme release induced by synthetic polycations. Pretreatment of PMNs with neuraminidase does not affect the ability of asbestos to induce enzyme release from these cells. Asbestos induces release of glucose from glucose-loaded liposomes, and this effect can be inhibited by the polyanion poly-D-glutamic acid. The results are compatible with the view that positive charges play a decisive role in the interaction between PMNs and asbestos, and that the primary target of asbestos could be the lipid bilayer of the membrane. The interaction results in a permeabilized plasma membrane. When Ca2+ is present in the medium it moves into the cell and causes exocytosis of the granule enzyme lysozyme. Inhibition of cytotoxicity by polyanion may cause a diminished Ca2+-influx and hence inhibition of lysozyme release.
