    Chloroquine transfection mechanism


    Transfections allow for transient expression of a gene of interest in a target cell line and can be useful for short term studies of protein function. We specifically use this protocol with Lenti-X 293T cells, a cell line optimized for production of lentiviral vectors.

    Despite the potent immunogenicity of viral vectors, their developed cell entry mechanism and high transfection efficiency in both dividing and non-dividing cells is desirable. Nowadays, non-viral vectors with minimal toxicity and immunogenicity have been developed to mimic the receptor-mediated cell entry mechanism of viruses. Recently, an altered chloroquine-transporter protein CG2 of the parasite has been related to chloroquine resistance, but other mechanisms of resistance also appear to be involved. Research on the mechanism of chloroquine and how the parasite has acquired chloroquine resistance is still ongoing, as other mechanisms of resistance are likely. Chloroquine is a member of quinolone family and is a weak intercalating agent. Chloroquine is used for treating amebiasis, rheumatoid arthritis, discoid and systemic lupus erythematosus. Application DNA intercalator. Also used to increase transfection efficiency. Chloroquine diphosphate salt has been used • in in vitro antiplasmodial assays

    Last Upload: June 10, 2016 Day 0: Seed Lenti-X 293T cells (this cell line is optimized for production of lentiviral vectors) Day 1 (pm): Transfect Cells Day 2 (am): 18h post transfection - Remove media, replace with fresh media Day 3 or more (am): Observe fluorescence, harvest cells, or perform your experiment *Pro-Tips* Different brands and lots of FBS can promote or inhibit transfection. This approach can be adapted for different cell lines and different transfection reagents.

  5. Chloroquine, which buffers lysosomes, enhanced the transfection efficiency of N‐quaternized PEIs and polylysine by 2–3‐fold. In contrast, chloroquine did not improve the transfection efficiency of PEI. The measured average pH environment of PEI vectors was 6.1, indicating that they successfully avoid trafficking to acidic lysosomes.

Chloroquine has been frequently used in cell culture gene transfection studies Cotton et al. 1992, Wagner et al. 1992, Lucas et al. 1995, but has not been reported yet to be successful for enabling gene transfection in vivo. As mentioned above, the mechanisms of action of chloroquine seems to be related to elevating the intravesicular pH.

    Stopping plaquenil. DailyStrength Hello all, I am currently new to this site and ran across the discussion about stopping Plaquenil. I have been taking Plaquenil for about 8-9 months and thought that it was not helping me because I still have a fair amount of joint pain, fatigue, muscle pain and so many other issues.

    Do either hydroxychol/Plaquenil put you at risk for.
