    Chloroquine antigen presentation


    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.

    Jul 13, 2012 They hypothesized that a short course of chloroquine could favour cross-presentation by blocking endosomal and phagosomal acidification, thus protecting antigens from degradation and favouring. The leaking proteins may become ubiquitinated in the cytosol and then, enhancing major histocompatibility complex MHC class I cross-presentation by antigen presenting cells. Therefore, administration of chloroquine promotes an increase in ubiquitinated proteins in cytosol that will be degraded in the proteasomes. CEL-SCI corporation announced that it is developing a preferentially directed immunotherapy using ligand antigen epitope presentation system LEAPS peptide technology to reduce COVID-19 viral load and consequent lung damage. Expert consensus on chloroquine phosphate for the treatment of novel coronavirus pneumonia.

    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.

    Antigen presentation plays a central role in initiating and maintaining an appropriate immune response to antigen. The process is tightly controlled at several levels as follows • different types of antigen-presenting cell APC are brought into play depending on the situation. Minocycline 0.1–0.4 mM gave significant inhibition of T cell response to TT and was equivalent to chloroquine. Inhibition was not observed when TT was incubated with APC before minocycline, indicating that presentation of preprocessed antigen was not inhibited. Chloroquine also reduces the proliferative responses to antigen and mitogen, possibly explained by impaired antigen processing 17, 18 and IL‐2 production 19. In contrast to these suppressive effects, chloroquine stimulates other cell functions like endothelial cell protease generation and cell migration 20.

    Plaquenil - Uses, Side Effects, Interactions - Plaquenil Hydroxychloroquine belongs to a group of medications known as anti-inflammatories and antimalarials. It is used alone or in combination with other anti-arthritic medications to treat rheumatoid arthritis. It helps to reduce pain, stiffness, and swelling in joints.
