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.

Sep 01, 1979 Variations of endocytic and of lysosomal functions during the cell cycle have been investigated in synchronized hepatoma cells derived from Morris hepatoma 7288c by following the cellular uptake of horseradish peroxidase, dextran mol wt. 70,000, and chloroquine. Chloroquine does not inhibit BMP-mediated Smad signalling and transcription of target genes. Since chloroquine inhibits the internalization of BMPR-II, it is possible that signalling downstream of the receptor could be adversely affected by this intervention. In addition, off-target effects of chloroquine might negatively impact BMP signalling. 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 . Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.

Unfortunately, Chloroquine, as well as other endosomal escape or endolytic agents, are often too toxic for use in preclinical models or eventual clinical trials of macromolecular therapeutics. Chloroquine is known to be a non-specific antiviral agent, but its effect on the Zika virus replication has not been evaluated yet. This is the first report of inhibitory effects of chloroquine on ZIKV replication, which, given the ongoing epidemics, may become interesting both for the scientific knowledge of the virus and for the clinical. Endocytosis occurs by a variety of mechanisms that are being dictated by the diversity of cargoes and cargo-specific transport kinetics, with the involvement of many genes. Table 1 lists the commonly studied genes involved in endocytosis and their antibodies cited among the articles in Labome's Validated Antibody Database.
