    Chloroquine endosomal escape mechanism

    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 lysosomotropic agent that prevents endosomal acidification 1. 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 pH, and prevents fusion of endosomes and lysosomes. With an octaarginine peptide R8 in liposomal escape from endocytic vesicles, using octalysine K8 as a control cationic peptide; the mechanism of endosomal escape of liposomes was also investigated. Gene expression of condensed plasmid DNA encapsulated in R8-modified nanoparticles was more than 1 The efficiency of functional delivery, in the presence and absence of endosomal escape enhancing compounds 25 μM chloroquine and 5 μM UNC10217832A, was analyzed by quantifying percentage of RFP.

    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 enhances endosomal escape by the proton sponge effect. Membrane permeable chloroquine is pro- tonated during endosome maturation resulting in Cl - and H 2 O influx, endosome swelling. Other endosomal escape mechanisms. Exogenous additives, such as chloroquine and inactivated adenovirus, have been exploited to promote endosomal escape and enhance the efficiency of nucleic acid delivery. This observation confirmed that the bulk of GFPβ11-S-S-TAT peptide remained trapped in endosomes and also demonstrated the ability of the split-GFP assay to detect additional endosomal escape. Unfortunately, Chloroquine, as well as other endosomal escape or endolytic agents, are often too toxic for use in preclinical models or eventual.
