BACKGROUND If mast cells are stimulated they release multiple mediators that delineate markers for immunologic and nonimmunologic reactions; histamine and tryptase are the two best known. Although histamine can be assayed in plasma, it is a nonspecific marker with a very short half-life. Tryptase has a longer half-life, but its release has not been proven to be specific for anaphylaxis. The aut...
Sarcolemmal membranes prepared by "gas dissection" from monolayers of cultured neonatal rat heart cells were studied with respect to their ability to bind calcium. Lanthanum displacement of calcium was 168 +/- 7 nmol/mg sarcolammel protein. This represents 3.21 mmol Ca/kg dry weight original cells on the basis of the measured membrane protein: dry cell weight ratio of 19.1 g/kg. Lanthanum-displ...
The aim of this study was to determine the role of intracellular proteins in phagocytosis of opsonized Porphyromonas gingivalis by RAW264.7 cells, a murine macrophage-like cell line. This periodontopathogen was grown anaerobically and opsonized with an IgG2a murine monoclonal anti-P. gingivalis lipopolysaccharide antibody. RAW264.7 cells were preincubated with protein tyrosine kinase inhibitors...
