    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.

    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. As antigen processing is an acidic, pH-dependent phenomenon, chloroquine turns off the process of antigen presentation by decreasing the number of autoantigenic peptides appearing on the cell surface. 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.

    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.

    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 lysosomotropic drug chloroquine has been added to cultures containing peripheral blood mononuclear cells PBMC and allogeneic antigen-presenting cells obtained from the epidermis of normal human skin or from skin of patients with psoriasis.
