    Chloroquine is a widely used biological research tool for studying autophagy inhibition. Research studies demon-strate that chloroquine accumulates in acidic lysosomes and increases the lysosomal pH. This inhibits lysosomal hydrolases and prevents autophagosomal fusion and degradation, which can result in apoptotic or necrotic cell death 1-4. Chloroquine is an aminoquinoline that is an inhibitor of autophagy and has antimalarial and anticancer activities. 1,2,3 Chloroquine inhibits autophagosome-lysosome fusion in HeLa cells when used at a concentration of 100 µM. 1 It is active against the chloroquine-sensitive GC03 strain of P. falciparum IC 50 = 29.2 nM but has decreased activity against mutant pfcrt P. falciparum IC 50 s. May 11, 2015 However, V-ATPase-deficient lysosomes remain competent to fuse with autophagosomes and endosomes, resulting in a time-dependent formation of giant autolysosomes. In contrast, BafilomycinA1 prevents autophagosome–lysosome fusion in these cells, and this defect is phenocopied by depletion of the Ca 2+ pump SERCA.

  5. Chloroquine treatment of cells leads to accumulation of light chain 3-II LC3-II 1-3. This autophagy marker resides within autophagosomal membranes during the autophagic process and is degraded upon fusion with lysosomes. Chloroquine inhibition of these fusion events effectively blocks LC3-II degradation.

    This is where currently clinically available drugs including chloroquine CQ and hydroxychloroquine HCQ inhibit autophagy by decreasing autophagosome/lysosome fusion. Newer. Jan 23, 2017 Chloroquine analog is a diprotic weak base. The unprotonated form of chloroquine diffuses spontaneously and rapidly across the membranes of cells and organelles to acidic cytoplasmic vesicles such as endosomes, lysosomes, or Golgi vesicles and thereby increases their pH Al‐Bari 2015. In this Commentary, we will summarize the current knowledge regarding autophagosome–lysosome fusion, focusing on mammals, and discuss the remaining questions and future directions of the field. Macroautophagy autophagy is a highly conserved intracellular degradation system that is essential for homeostasis in eukaryotic cells. Due to the.
