Modulation of lysosomal protease-esterase and lysozyme in Kupffer cells and peritoneal macrophages infected with Nocardia asteroides
Abstract
Virulent Nocardia asteroides reduces lysosomal acid phosphatase activity in murine macrophages. A computer-assisted imaging photometry system was used to quantitate lysozyme and nonspecific esterase-neutral protease levels within individual macrophages following ingestion of nocardiae. In contrast to acid phosphatase, lysozyme and esterase-neutral protease activity was either unchanged or increased following infection by increasing numbers of nocardial cells.
