    Chloroquine lysing the endosome


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Drug release from liposomes in the endosome-lysosomal organelles into cytoplasm is critical to cytotoxicity and anticancer effects. Chloroquine is a lysosomotropic agent that has been reported to enhance in vitro cytotoxicity of basic anticancer drugs. To investigate the mechanism of chloroquine triggering basic anticancer drugs release from liposomes and the potential to treat solid tumors in clinic, daunorubicin was loaded into folate-targeted liposomes by ammonium sulfate remote loading. Sep 15, 2013 Chloroquine is a lysosomotropic agent as it is usually prepared as a diprotic weak base pKa 8.5. The unprotonated form of chloroquine preferentially accumulates in lysosomes as it rapidly diffuses across cell/organelle membranes. The Toll-like receptors TLRs are key initiators of innate and adaptive immune responses through production of proinflammatory cytokines and chemokines, upregulation of costimulatory molecules and activation of antigen presentation Akira and Takeda, 2004. The signaling receptor for lipopolysaccharide LPS is TLR4/MD-2 receiving LPS from CD14.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  4. Aug 22, 2005 Severe acute respiratory syndrome SARS is an emerging disease that was first reported in Guangdong Province, China, in late 2002. The disease rapidly spread to at least 30 countries within months of its first appearance, and concerted worldwide efforts led to the identification of the etiological agent as SARS coronavirus SARS-CoV, a novel member of the family Coronaviridae.

    • Chloroquine is a potent inhibitor of SARS coronavirus..
    • Endocytic pathways regulate Toll-like receptor 4 signaling and link..
    • Chloroquine is a potent inhibitor of SARS coronavirus infection and spread.

    The TLR pathway is then activated, and IFN-α is secreted by these activated pDCs. As chloroquine could potentially inhibit the acidification of the endosome, where the most important steps in pDC activation occurs, it might have potential uses as an anti-AIDS drug by acting to inhibit immune activation and slow disease progression. Aug 13, 2012 Chloroquine could disrupt the endosomal TLR pathway by inhibiting the acidification of the endosome, which is crucial for pDC activation and subsequent IFN-α secretion. 10 Consequently, it is. The addition of chloroquine neutralises the luminal pH, revealing the presence of any tagged receptors within the lumen of the endosome Fig. 4A and B. Following agonist treatment for 90 min, both the M2R and M2R-0cK can clearly be seen internalized from the plasma membrane onto the limiting membrane of the enlarged endosomal structures Supplemental Figs. 3B and C.
