    Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation. Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped. Protonated chloroquine then changes the lysosomal pH, thereby inhibiting autophagic degradation in the lysosomes. Jan 23, 2017 Chloroquine analog is a diprotic weak base. The unprotonated form of chloroquine diffuses spontaneously and rapidly across the membranes of cells and organelles to acidic cytoplasmic vesicles such as endosomes, lysosomes, or Golgi vesicles and thereby increases their pH Al‐Bari 2015.

  3. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4.

    Lysosome fusion are least understood, although there have been several recent advances. In this Commentary, we will summarize the current knowledge regarding autophagosome–lysosome fusion, focusing on mammals, and discuss the remaining questions and future directions of the field. Chloroquine has antiviral effects, which work by increasing endosomal pH resulting in impaired virus/cell fusion that requires a low pH. 32 33 Chloroquine also seems to act as a zinc ionophore, thereby allowing extra cellular zinc to enter inside the cell and inhibit viral RNA dependant RNA polymerase. The effect of Bafilomycin on autophagosome-lysosome fusion is complex and time dependent in each cell line. In neurons, an increase in the autophagosome marker LC3-II has been seen with Bafilomycin treatment. This occurs as autophagosomes fail to fuse with lysosomes, which normally stimulates the degradation of LC3-II.

    Plaquenil & weight loss Lupus Forums at The Lupus Site Just wondering if anyone else had problems with loss of appetite and weight loss while on plaquenil. I had my dose increased to 400mg a day about three weeks ago, and since then I have no appetite whatsoever. Weight is falling off me at a rather alarming rate - at least half a stone a week.

    Allergie au soleil symptômes & traitements Creapharma D’autres scientifiques et médecins pensent en fait qu’il ne s’agit pas vraiment d’une allergie au soleil mais plutôt une forme de douleur musculaire provoquée par le soleil. Parler d'”allergie au soleil” serait donc un abus de langage, car il n’a pas été de prouvé que le soleil était vraiment l’allergène.
