Chloroquine is a lysosomotropic agent that prevents endosomal acidification [1].

Oral administration of chloroquine, which inhibits autophagy, did not suppress damage to microglia and pericytes, but greatly reduced neuronal vacuolation and eliminated neuronal cells with abnormal inclusions. Thus, decreasing autophagy appears to prevent neuronal degeneration. Chloroquine diphosphate is an antimalarial and anti-inflammatory drug widely used to treat malaria and rheumatoid arthritis. Chloroquine diphosphate is an inhibitor of autophagy and toll-like receptors TLRs.

    This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes. TLR7/8-Mediated Activation of Human NK Cells Results in Accessory Cell-Dependent IFN- Production. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes.

  7. Chloroquine inhibits autophagic flux by decreasing autophagosome-lysosome fusion. We show that CQ mainly inhibits autophagy by impairing autophagosome fusion with lysosomes rather than by affecting the acidity and/or degradative activity of this organelle. which might contribute to the fusion impairment. Strikingly, HCQ-treated mice.

    Chloroquine inhibits autophagy by blocking acidification of the lysosome, preventing fusion with the autophagosome. In a stressed cell, dependent on autophagy, this last step when blocked results in increased generation of autophagosomes, eventually undergoing either apoptotic or necrotic cell death. These studies provide evidence that autophagy serves as a survival pathway in tumor cells treated with apoptosis activators and a rationale for the use of autophagy inhibitors such as chloroquine in combination with therapies designed to induce apoptosis in human cancers. 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.

    Suppression: 400 mg (310 mg base) orally on the same day every week Comments: -Suppressive therapy should begin 2 weeks prior to exposure; however, failing this, an initial dose of 800 mg (620 mg base) may be taken in 2 divided doses (6 hours apart).
