Dynamic macrophage “probing” is required for the efficient capture of phagocytic targets
Binding of ligands by immunoreceptors is thought to be a passive, stochastic process. Contrary to this notion, we found that binding of IgG-opsonized particles by Fcγ receptors was inhibited in macrophages, dendritic and microglial cells by agents that interfere with actin assembly or disassembly. Changes in the lateral mobility of the receptors--assessed by single-particle tracking--or in the ...

WASH is required for lysosomal recycling and efficient autophagic and phagocytic digestion
Wiskott-Aldrich syndrome protein and SCAR homologue (WASH) is an important regulator of vesicle trafficking. By generating actin on the surface of intracellular vesicles, WASH is able to directly regulate endosomal sorting and maturation. We report that, in Dictyostelium, WASH is also required for the lysosomal digestion of both phagocytic and autophagic cargo. Consequently, Dictyostelium cells...

15 صفحه اولP-71: Construction of Required DNA Plasmids for Validation of Predicted MicroR-NA Targets
Background: The micro-ribonucleic acids (miRNAs) are noncoding RNA molecules that are conserved developmentally and include usually 18-25 nucleotides. MiRNA regulates gene expression through mRNA degradation or inhibiting of its translation. These biomolecules contribute in cellular physiologic and pathologic processes and most of them may act as oncogenes or tumor inhibitors. Identification of...
