    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.

    Inhibition by chloroquine of the class II major histocompatibility complex-restricted presentation of endogenous antigens varies according to the cellular origin of the antigen-presenting cells. 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. The inhibition of antigen presentation by chloroquine is specific for the antigen processed in the presence of chloroquine A 20-1.11 B lymphoma accessory cells T cell hybridoma IL-2 production First antigen' Chloroquineb Second antigenC OVA specific KLH pulse treatment pulse DO-II specific after AODK 1.16 first antigen OVA 640 0 OVA KLH 640.

    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.

    A low pH is required for digestion of the protein by acidic hydrolases in the lysosome, for assembly of the α–β–peptide complex and for its transport to the cell surface. Chloroquine and hydroxychloroquine are weak diprotic bases that can diffuse across the cell membrane and raise the pH within cell vesicles.

Invariant chain CLIP peptide and chains of MHC class II molecules CLIP A peptide of the invariant chain blocks the MHC molecule binding site. Antigen presentation describes a vital immune process which is essential for T cell immune response triggering. Because T cells recognise only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment, now bound to the major histocompatibility complex MHC, is transported to the surface of the cell, a process known as presentation, where it can.
