    Do i need to use chloroquine in lentiviral transduction


    The term is often used whatever the delivery tool but actually it should not! Transfection of DNA or RNA into animal cells has to be restricted to non-viral systems that transiently open pores into the cell membrane to permit the entry of nucleic acids.

    Unfortunately, results are not always living up to expectations. To prevent failure, several parameters must be taken into account. We describe in this article 10 best practices to follow for a good transduction efficiency. In order to efficiently transduce the cells of interest, the transduction mix has to be left on the seeded cells for a minimal amount of time enhancer + complete cell culture media + viral supernatant. All lentiviral vectors present in the transduction mix need at least 5 hours to penetrate the cells of interest. For CaPO3, I use chloroquine, which inhibits DNA degradation by lysosomes by raising their pH - but this is toxic to the cell, so media must be changed after 6-8 hr. PEI also prevents DNA.

    If DNA or RNA is introduced into cells by using viral vector carriers, then the technique is called Transduction, and the resulting cells are said to be transduced! It non only includes chemical-based products such as calcium phosphate, cationic polymers (PEI) and liposomes, but also non-chemical methods such as electroporation.

  4. Answer. For hard to transfect, non-dividing cells, Lentiviral transfection offers a high efficiency solution for attaining good expression levels. However, the time and difficulty associated with lentiviral production makes this method difficult and time consuming. In addition, a proper safety-level lab is necessary for production and use.

    Lentiviral production and transduction. Once you have cloned your gene of interest into lentiviral transfer vector, the next step is to produce the viral particles themselves. For this you will first need to transfect producing cells, usually 293T cells, with your transfer plasmid and your packaging plasmids. Introduction. This protocol can be used to generate stable cell lines expressing a gene of interest from an integrated lentiviral vector. Unlike the short term protein expression observed using transient transfection approaches, generating cell lines using lentiviral vectors enables long-term protein expression studies. If you’re planning on using lentivirus for your next experiment, chances are you’re wondering how much virus to use. For in vitro work, multiplicity of infection MOI is the theoretical number of virus particles applied per target cell. That is to say, if you have 1 million cells and you want an MOI of 5, you need 5 million lentivirus particles for your transduction.

    Dosing schedules not well established in children Case reports describe dosage regimens that are effective yet tolerated, such as 12.5 mg PO twice weekly over 2 yr in a child aged 4-6 yr, and 100 mg PO twice weekly over 5 months in a child aged 12 yr; mg/kg dosing not reported Hypersensitivity to chloroquine, 4-aminoquinolones Psoriasis, porphyria, retinal or visual field changes For prevention, may use proguanil concomitantly Shown to cause severe hypoglycemia including loss of consciousness that could be life-threatening in patients treated with or without antidiabetic medications; patients should be warned about risk of hypoglycemia and associated clinical signs and symptoms; patients presenting with clinical symptoms suggestive of hypoglycemia during treatment with chloroquine should have blood glucose level checked and treatment reviewed as necessary Not effective in most areas; CDC recommends mefloquine or atovaquone/proguanil - check CDC traveler information for specific recommendations for region May cause hemolysis in glucose-6 phosphate dehydrogenase (G-6-PD) deficiency; blood monitoring may be needed as hemolytic anemia may occur, in particular in association with other drugs that cause hemolysis Monitor CBC periodically with prolonged therapy Caution with history of auditory damage Caution with hepatic disease, alcoholism, and coadministration with other hepatotoxic drugs May provoke seizures in patients with history of epilepsy Antacids and kaolin reduce chloroquine absorption; separate administration by at least 4 hr Irreversible retinal damage observed in some patients; significant risk factors for retinal damage include daily doses of chloroquine phosphate 2.3 mg/kg of actual body weight, durations of use greater than five years, subnormal glomerular filtration, use of some concomitant drug products such as tamoxifen citrate, and concurrent macular disease A baseline ophthalmological examination should be performed within the first year of initiating therapy; for individuals with significant risk factors, monitoring should include annual examinations; discontinue if ocular toxicity is suspected; patient should be closely observed given that retinal changes (and visual disturbances) may progress even after cessation of therapy In individuals of Asian descent, retinal toxicity may first be noticed outside macula; it is recommended that visual field testing be performed in visual field of central 24 degrees instead of central 10 degrees May exacerbate heart failure Not effective against chloroquine- or hydroxychloroquine-resistant strains of Plasmodium species; information regarding geographic areas where resistance to chloroquine occurs, is available at the Centers for Disease Control and Prevention (gov/malaria) Does not treat hypnozoite liver stage forms of Plasmodium and will therefore not prevent relapses of malaria due to P. ovale; additional treatment with an anti-malarial agent active against these forms, such as an 8-aminoquinoline, is required for the treatment of infections with P. ovale Cases of cardiomyopathy resulting in cardiac failure, in some cases with fatal outcome, reported during long term therapy at high doses; monitor for signs and symptoms of cardiomyopathy and discontinue chloroquine if cardiomyopathy develops; chronic toxicity should be considered when conduction disorders (bundle branch block / atrio-ventricular heart block) diagnosed; if cardiotoxicity suspected, prompt therapy discontinuation may prevent life-threatening complications QT interval prolongation, torsades de pointes, and ventricular arrhythmias reported; risk is greater if chloroquine is administered at high doses; fatal cases reported; use with caution in patients with cardiac disease, a history of ventricular arrhythmias, uncorrected hypokalemia and/or hypomagnesemia, or bradycardia ( There are no adequate and well-controlled studies evaluating the safety and efficacy of chloroquine in pregnant women; usage during pregnancy should be avoided except in prophylaxis or treatment of malaria when benefit outweighs potential risk to fetus Because of the potential for serious adverse reactions in nursing infants from chloroquine, a decision should be made whether to discontinue nursing or to discontinue drug, taking into account potential clinical benefit of drug to mother A: Generally acceptable.
