    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. Chloroquine and hydroxychloroquine can prevent the development and progression of pulmonary hypertension induced by monocrotaline in rats. Chloroquine therapy, via inhibition of autophagy, increases apoptosis and inhibits proliferation of pulmonary artery smooth muscle cells in pulmonary hypertensive arteries. DNA delivered in nonviral vectors or as naked DNA must overcome a number of extracellular and intracellular barriers to transfection. Since many vectors deliver DNA into cells by the endocytic route, DNA degradation by lysosomal nucleases has been proposed as a significant barrier to transfection, despite the fact that this has not yet been formally demonstrated to occur. To test this.

  6. The chloroquine enhanced transfection procedure provides a reliable and reproducible assay of released protein and its effect is presumably mediated through its pH elevating effect on the lysosomal compartment, thereby, protecting DNA molecules from nuclease degradation.

    Dual treatment with inhibitors of the UPS MG312 and autophagy chloroquine or bafilomycin or ablation of autophagy pathway by sh-RNA mediated Beclin1 or p62 knockdown revealed that autophagy-lysosomal pathway plays a crucial role in degradation of EBNA3C and possibly along with other protein aggregates caused by UPS inhibition. Activity of lysosomal enzymes such as proteases and nucleases. Moreover, the increased pH deact ivates P-gp in lysosomal mem-brane and finally leads to the drug efflux from lysosomes 17,18, 2 it can act as an osmotic agent increasing the osmotic pressure of the endosomes resulting in swelling and rupture of endosomal membrane 16. What i mean is just as follow The autophagy inhibitor,chloroquine, functions when autophagosome fuses to lysosome. As a result, use of chloroquine makes it blocked for LC3B-II to degrade in lysosome. Here comes the question When cell stressedfor examplestarvation, chloroquine will furthermore get LC3B-II.

    Stopping Plaquenil - General Discussion - Life With Lupus My new rheumy, after running a trillion tests, has said that if it weren't for my previous rheumy's test results, he would say I did not have lupus. So, I asked about coming off of plaquenil. He said that I could stop plaquenil cold turkey. It slowly decreases effectiveness in the body.
