Webb25 okt. 2010 · During Fcγ receptor (FcR)-mediated phagocytosis by macrophages, cytoplasm advances over IgG-coated particles by the sequential ligation of FcR in plasma membranes. If FcR signaling was strictly autonomous, then the signals generated during phagocytosis should be proportional to the number of ligated receptors. WebbB cells play a central role in antibody-mediated rejection and certain autoimmune diseases. However, B cell–targeted therapy such as anti-CD20 B cell–depleting antibody (aCD20) has yielded mixed results in improving outcomes. In this study, we investigated whether an accelerated B cell reconstitution leading to aCD20 depletion resistance could account …

"Webb1 feb. 2007 · This process requires formation of clathrin-coated vesicles and occurs independent of actin polymerization. In contrast, agLDL, acLDL and oxLDL are internalized through receptor mediated phagocytosis which occurs by an clathrin-independent mechanism but is ATP- and actin-dependent and involves formation of pseudopodia.

Mechanics of receptor-mediated endocytosis PNAS

WebbIntegrin- and Fc receptor (FcR)–mediated uptake are examples of receptor-mediated phagocytosis, through which particles are internalized into membrane-bound vacuoles called phagosomes. FcRs mediate uptake of antibody-opsonized particles (e.g., … WebbFunctionally, FrLRR mediated and promoted bacteria-binding and phagocytosis, and FrLRR antibody blocking or Grb2 knockdown inhibited FrLRR-mediated phagocytosis. Interestingly, we found that human Slit2-N (hSlit2-N) also mediated direct bacteria-binding and phagocytosis which was inhibited by Slit2-N antibody blocking or Grb2 knockdown.

WebbPI3K and NADPH oxidase were crucial for both cytokine secretion and ROS generation, whereas Syk signaling mediated only cytokine production. Our results highlight the mechanism by which phagocytosis tightly controls the activation of phagocytes by fungal pathogens and strongly suggest that actin cytoskeleton dynamics are an essential … WebbCRs-Mediated Phagocytosis and Measurement Regulation of CR-mediated phagocytosis is more complicated than simple activation of adhesion within cells. A few decades ago, scientists reported that macrophages can bind complement-opsonized targets but can't phagocytose them without an attached signal.

Both processes are actin-mediated and both involve …

WebbIn receptor-mediated endocytosis, binding of molecules such as hormones, antibodies and other proteins, and lipids to specific receptors in the plasma membrane is followed by their clustering (i.e., concentration) at specific membrane sites, which are then internalized by the cell. The process is depicted diagrammatically in Figure 15-44. WebbReceptor-mediated phagocytosis was required for mTORC1 activation, which could not be achieved by phagocytosis of latex beads.
