    Chloroquine and osmotic lysis of endosome

    The cell's membrane is not large enough to accommodate the excess fluid, causing the membrane to break open, or lyse. Maintaining an osmotic balance is a very basic but very important function of the cell membrane to prevent cytolysis.

    Mar 11, 2002 In the case of influenza virus, inhibitors of lysosomal acidification have been shown to be effective as prophylactics and in shortening the course of disease 12, 28. In the case of human immunodeficiency virus HIV, electron microscopy has been used to document viral fusion with the plasma membrane. Chloroquine is a weak base that can rapidly penetrate the plasma membrane, accumulate in acidic vesicles and increase the pH of the acidic compartment Maxfield 1982; Mellman, Fuchs et al. 1986. Preventing endosome acidification may subsequently inhibit hydrolytic enzymes such as proteases and nucleases Cotten, Längle-Rouault et al. 1990. Chloroquine is effective in preventing the spread of SARS CoV in cell culture. Favorable inhibition of virus spread was observed when the cells were either treated with chloroquine prior to or after SARS CoV infection.

    Cells are the basic functional unit of the body and of life. Most of the things that cells do depend on the flow of certain ions into and out of the cell.

  7. Osmotic lysis of pinosomes has already been used with a number of cultured cell lines to study intracellular proteolysis, cytoplasmic pH changes, Ca 2+ movements, and uptake of toxins, and to introduce antibodies into the cytoplasm for the studies on microtubule function. Rates of pinocytosis are under physiological control, and they can be manipulated by growth conditions and various chemicals.

    Endosome lysis was seen at 45 min for PEI but not POL-containing endosomes, and PEI-containing endosomes showed increased osmotic fragility in vitro. The slowed endosomal acidification and enhanced Cl - accumulation and swelling/lysis were accounted for by the greater H + buffering capacity of endosomes containing PEI or PAM versus POL 90 m m versus 46 H + /pH unit. The aim of the present in vitro study was to ascertain the tendency of two quinoline quinine and chloroquine phosphate drugs to interfere with osmotic stability of three human erythrocyte genotypes, namely, HbAA, HbAS and HbSS. Spectrophotometric method was used for determination of the capacity of the erythrocyte genotypes to withstand.

    If you have high cholesterol, you’re also at higher risk for heart disease. You can lower your “bad” LDL cholesterol and raise your “good” HDL cholesterol. “I tell patients that you have to start somewhere and just keep going,” says Suzanne Steinbaum, DO, an attending cardiologist at Lenox Hill Hospital in New York City.

    Hydroxychloroquine Side-effects, uses, time to work Hydroxychloroquine is a disease-modifying anti-rheumatic drug DMARDregulates the activity of the immune system, which may be overactive in some conditions. Hydroxychloroquine can modify the underlying disease process, rather than simply treating the symptoms.
