OBJECTIVE Apoptotic monocytes release membrane microparticles which may play a major role in thrombogenicity through a P-selectin glycoprotein ligand (PGSL-1)-mediated mechanism. We have studied systematically the regulation of PSGL-1 expression and function in apoptotic monocytic cells. METHODS AND RESULTS PSGL-1 expression (flow cytometry, immunofluorescence microscopy, immunoblot) was virt...
The aspartic protease cathepsin D (CD) is a key mediator of induced-apoptosis and its proteolytic activity has been generally involved in this event. During apoptosis, CD is translocated to the cytosol. Since CD is one of the lysosomal enzymes that requires a more acidic pH to be proteolytically-active relative to the cysteine lysosomal enzymes such as cathepsin-B and cathepsin-L, it is therefo...
AIM To determine the effect of dilute hydrochloric acid on the in situ end labelling (ISEL) reaction, with and without a variety of different proteolytic enzymes. METHODS Sections of tissue fixed in buffered formalin were pretreated with trypsin, protease XIV (at two different concentrations), or protease XXIV (for two different incubation times), with and without subsequent 1 M hydrochloric ...
The apoptotic protease-activating factor 1 (Apaf-1) receives the death signal in the intrinsic ormitochondrial pathway of apoptosis. Upon the releasing of cytochrome c from theintermembrane space of mitochondria and binding to Apaf-1 molecules, a heptamericapoptosome complex is formed and triggers the downstream cascade of caspases. Here, for thefirst time we present spontaneous mutations and r...
Both necrotic and apoptotic neuronal death are observed in various neurological and neurodegenerative disorders. Calpain is activated in various necrotic and apoptotic conditions, while caspase 3 is only activated in neuronal apoptosis. Despite the difference in cleavage-site specificity, an increasing number of cellular proteins are found to be dually susceptible to these cysteine proteases. T...
Apoptotic cells were shown to induce dendritic cell immune tolerance. We applied a proteomic approach to identify molecules that are secreted from apoptotic monocytes, and thus may mediate engulfment and immune suppression. Supernatants of monocytes undergoing apoptosis were collected and compared using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and differentially exp...
