    The autophagic process is also used to remove intracellular microbial pathogens. Several signaling pathways sense different types of cell stress, ranging from nutrient deprivation to microbial invasion, and converge to regulate autophagy at multiple stages of the process.

    Endosomal Acidification Inhibitor. 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. In vitro, optimal NDV infection of the host cells is significantly affected by drugs such as chloroquine that inhibit endosomal acidification Sanchez‐Felipe et al. 2013. NDV infection induces autophagy and inhibition of autophagy by the analog reduces the viral replication and infection Meng et al. 2012; Sun et al. 2013. Inhibitors of positive regulators of of the ULK complex and Beclin1 have been demonstrated to block autophagy. These include inhibitors to the MAP kinases, JNK1, ERK and p38. The induction of Atg protein and LC3 proteins is required for vesicle expansion and formation. Inhibitors of the class III PI3 kinases can block autophagy.

    Inhibitors of positive regulators of of the ULK complex and Beclin1 have been demonstrated to block autophagy. The primary step in inducing autophagy involves membrane nucleation, controlled by ULK complex and Beclin1.

  7. 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.

    Confluent LLC-PK cells cultured in 12 well plates were pre-treated with mock medium or an inhibitor of endosomal acidification chloroquine, 70 μM for 1 h. Cells were then infected with PEC at an MOI of 50 in the presence of chloroquine or mock at 37°C. Chloroquine has antiviral effects, which work by increasing endosomal pH resulting in impaired virus/cell fusion that requires a low pH. 32 33 Chloroquine also seems to act as a zinc ionophore, thereby allowing extra cellular zinc to enter inside the cell and inhibit viral RNA dependant RNA polymerase. Reported in other studies using CQ as an endosomal disrupting molecule 22,28–30. Endosomal escape remains one of the serious challenges in nucleic acid therapy. Among current solutions for enhanced endosomal escape, chloroquine is one of the promising can-didates by being inexpensive, physicochemically stable and effective.

    Hydroxychloroquine Uses, Dosage & Side Effects - Mar 17, 2019 Hydroxychloroquine is a quinoline medicine used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia.
