Fluid-phase uptake by macropinocytosis in Dictyostelium.
To study fluid-phase endocytosis in living cells and its relationship to changes in the cell cortex, we have used a green fluorescent protein (GFP)-tagged version of coronin, an actin-associated protein that localises to dynamic regions of the Dictyostelium cell cortex. In the confocal microscope, internalisation of fluorescently labelled dextran as a fluid-phase marker can be recorded simultan...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولThe pathogenesis of foam cell formation: modified LDL stimulates uptake of co-incubated LDL via macropinocytosis.
Previously, modified LDLs were shown to stimulate macropinocytosis in pigeon macrophages. Simultaneous intracellular trafficking of LDL and AcLDL, differentially labeled with colloidal gold, was done to determine whether uptake of LDL, which does not cause foam cell formation, was internalized via a separate route from AcLDL, which stimulates foam cell formation. AcLDL and LDL were followed at ...

15 صفحه اولMacropinocytosis is the endocytic pathway that mediates macrophage foam cell formation with native low density lipoprotein.
Previously, we reported that fluid-phase endocytosis of native LDL by PMA-activated human monocytederived macrophages converted these macrophages into cholesterol-enriched foam cells (Kruth, H. S., Huang, W., Ishii, I., and Zhang, W. Y. (2002) J. Biol. Chem. 277, 34573-34580). Uptake of fluid by cells can occur either by micropinocytosis within vesicles (<0.1 microm diameter) or by macropinocyt...
