    Chloroquine and lysosome ph


    It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes.

    The chloroquine-mediated rise in endosomal pH modulates iron metabolism within human cells by impairing the endosomal release of iron from ferrated transferrin, thus decreasing the intracellular concentration of iron. Chloroquine raises the pH in host-cell lysosomes, which interferes with viruses’ attempts to acidify the lysosomes, a prerequisite to formation of the autophagosomes that cells use to eat themselves. In the Cell Research paper, the researchers found that the drug was effective at inhibiting the virus as it was both entering and exiting cells. Rlyso, a highly selective and sensitive pH sensor, can stain lysosomes with a novel lysosome-locating group, methylcarbitol. Rlyso was successfully used to detect lysosomal pH changes during apoptosis or induced by chloroquine while avoiding the “alkalizing effect” on lysosomes of current lysosomal

    Moreover, Chloroquine inhibits autophagy as it raises the lysosomal p H, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4]. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.

    Nov 25, 2019 Chloroquine is an anti-malaria medicine that works by interfering with the growth of parasites in the red blood cells of the human body. Parasites that cause malaria typically enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. Chloroquine is used to treat and to prevent malaria. It accumulates in the acidic lysosome as it becomes protonated, increasing the pH of the lysosome 35,36. Following exposure to concanamycin A, BMPR-II accumulates in the lysosome, but with chloroquine treatment BMPR-II appeared to be increased at the plasma membrane in addition to a degree of lysosomal accumulation. Hemozoin collects in the digestive vacuole as insoluble crystals. Chloroquine enters the red blood cell, inhabiting parasite cell, and digestive vacuole by simple diffusion. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4. 7; chloroquine then cannot leave by diffusion.
