Phagosome Maturation: Aging with pH, Lysosome-associated membrane proteins, and Cholesterol; while staying young with Burkholderia cenocepacia

TL;DRAbstract

Phagocytosis is an innate immune response that is paramount in the clearance of pathogenic particles. Recognition of target particles by phagocytic receptors expressed on phagocytes induces modifications in the underlying actin cytoskeleton to form pseudopods that encircle and internalize the target particle into a membrane bound organelle called the phagosome. The nascent phagosome undergoes a maturation sequence that is characterized by substantial
\nremodeling of the membrane and its luminal contents through interactions with components of the endocytic pathway, culminating in an acidic and hydrolytic organelle capable of digesting and elminating pathogens. Phagosome maturation is a complicated pathway that involves many
\nprotein and lipid signaling molecules. Several factors that influence phagosome maturation particularly the participation of pH, lysosome-associated membrane proteins-1 and –2, cholesterol, in addition to the survival and escape mechanisms used by, Burkhol
