  1. Microglial Phagocytosis of Bacteria and Synapses

    … pathogens - including bacteria and fungi - via phagocytosis. However, the mechanisms that regulate these phagocytic events are not clear. In this work, involvement of calreticulin, galectin-3, apolipoprotein E and β-amyloid in microglial phagocytosis of bacteria were studied. Microglia activated …

  4. Membrane Surface Charge and Lipid Signaling in Phagocytosis

    Phagocytosis is an important component of innate and adaptive immunity. The formation of phagosomes and the subsequent maturation that capacitates them for pathogen elimination and antigen presentation are complex processes that involve signal transduction, cytoskeletal reorganization and membrane …
