    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.

    Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. 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. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4.

    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.

    Chloroquine promotes escape of polyplexes or lipoplexes from endosome via increasing endosomal pH and hindering endosome fusion with lysosome. To date, chloroquine has been widely used to elucidate the uptake mechanism of non-viral nucleic acid delivery systems Legendre and Szoka Jr 1992 ; Simeoni, Morris et al. 2003 ; Lehto, Abes et al. 2010. Chloroquine was shown to inhibit LPS-induced activation of extracellular signal-regulated kinase ERK 1/2 in human PBMCs and the expression of the TNF-α promoter-driven reporter gene in human monocytic THP-1 cells, suggesting that chloroquine blocks transcription of the TNF-α gene by interfering in LPS-induced activation of the ERK1/2 signalling pathway. The chloroquine-induced decrease in IL-1β and IL-6 mRNA has not been studied in detail, and the underlying mechanism is unknown. 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 patient's hypotension resolved within 4.5 hours, serum potassium stabilized in 24 hours, and tachycardia gradually decreased over 3 days. Interactions.
