Cationic protein-bearing granules of polymorphonuclear leukocytes: separation from enzyme-rich granules.

摘要: The cationic, antibacterial proteins of polymorphonuclear leukocytes are associated with a unique subcellular particle that is separable through zonal density gradient centrifugation from acid phosphatase-containing particles as well contain alkaline phosphatase and lysozyme. Normal macrophages, macrophages stimulated by bacillus Calmette-Guerin, liver cells lack this the group cationic proteins. Particles physically biochemically similar to slower sedimenting enzyme-rich shared all tlhree cell types.
