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. TLR7/8-Mediated Activation of Human NK Cells Results in Accessory Cell-Dependent IFN- Production. Hydroxychloroquine and blood sugar Plaquenil and glaucoma Chloroquine treatment of cells leads to accumulation of light chain 3-II LC3-II 1-3. This autophagy marker resides within autophagosomal membranes during the autophagic process and is degraded upon fusion with lysosomes. Chloroquine inhibition of these fusion events effectively blocks LC3-II degradation. The LC3-II/I ratio reflects the conversion of the protein from the cytosolic form to the autophagosome associated form upon autophagy activation and was also calculated and showed significant increases for both bafilomycin and chloroquine treatments, although chloroquine was statistically further increased, albeit modestly, from bafilomycin. Feb 05, 2010 A similar concern is also true for the measurement of LC3-II. For example, if cells are cultured with chloroquine, an agent that impairs lysosomal acidification, LC3-II accumulates even under normal nonstarved conditions because turnover of LC3-II by basal autophagy is blocked Figure 6A. Thus, one cannot distinguish between bona fide induction of autophagy e.g. by starvation and impairment of autophagolysosomal maturation simply by measuring autophagosome numbers e.g. by electron. 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.

Chloroquine-induced autophagic vacuole accumulation and cell.. Methods in Mammalian Autophagy Research - PubMed Central PMC. Best way to quantitatively measure Autophagic Flux, Novus.. P62 is a receptor for cargo destined to be degraded by autophagy, including ubiquitinated protein aggregates destined for clearance. The p62 protein is able to bind ubiquitin and also to LC3, thereby targeting the autophagosome and facilitating clearance of ubiquitinated proteins. Invitrogen Molecular Probes tools enable Tracking p62 in live cells Since autophagy is a constitutive cellular degradation process, the use of an autophagy detection reagent will prevent the lysosomal degradation of LC3, allowing its quantification by flow cytometry. The monomeric GFP used in our fusion protein to LC3 is attached on the 5' end N-terminal fusion, protecting the GFP from Atg4 cleavage, thus, allowing its visualization within the autophagosomes. Immunocytochemistry Analysis A 0 dilution of this antibody detected LC3 in serum-starved, chloroquine-treated HeLa cells. A punctate distribution is seen, evidence of autophagy conditions within the cell.
