    Chloroquine lysing the endosome

    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Chloroquine was shown to inhibit LPS-induced activation of extracellular signal-regulated kinase ERK 1/2 in human PBMCs and the expression of the TNF-α promoter-driven reporter gene in human monocytic THP-1 cells, suggesting that chloroquine blocks transcription of the TNF-α gene by interfering in LPS-induced activation of the ERK1/2 signalling pathway. The chloroquine-induced decrease in IL-1β and IL-6 mRNA has not been studied in detail, and the underlying mechanism is unknown. The addition of chloroquine neutralises the luminal pH, revealing the presence of any tagged receptors within the lumen of the endosome Fig. 4A and B. Following agonist treatment for 90 min, both the M2R and M2R-0cK can clearly be seen internalized from the plasma membrane onto the limiting membrane of the enlarged endosomal structures Supplemental Figs. 3B and C. The Toll-like receptors TLRs are key initiators of innate and adaptive immune responses through production of proinflammatory cytokines and chemokines, upregulation of costimulatory molecules and activation of antigen presentation Akira and Takeda, 2004. The signaling receptor for lipopolysaccharide LPS is TLR4/MD-2 receiving LPS from CD14.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

    Chloroquine Phosphate. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat amebiasis, an infection of the intestines caused by a parasite. Dec 22, 2006 Effect of chloroquine treatment on the levels of endosome-binding proteins in PC12 cells. PC12 cells were treated with 1 μM chloroquine for 5 days. A Cell lysates were subjected to Western blotting using CTB-HRP and specific antibodies.

    Evaluation of efficacy of combination of methotrexate and. This study evaluates the efficacy of the combination of methotrexate and hydroxychloroquine against leflunomide, a new DMARD as initial therapy in severe active rheumatoid arthritis. Hydroxychloroquine is known to increase the potency of methotrexate as well as increase its safety profile and reduce the dose.

    Which would you pick and why? - Plaquenil or Methotrexate
