    Block mhc chloroquine

    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.

    Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. Newly synthesized HLA class I molecules–β 2-microglobulin–peptide complexes are transported from the endoplasmic reticulum ER to the cell surface for presentation to and recognition by CD8 + CTLs. 33,34 The fungal product brefeldin A blocks the MHC class I processing pathway by specifically inhibiting the vesicular egress from the ER and the Golgi complex. 35,36 As demonstrated in Figure 4, incubation of DCs with brefeldin A reduced the lysis of MUC1 RNA-transfected DCs, while it had. Chloroquine per week starting at least 1 week before. traveling to the area where malaria transmission occurs. They should take one dose per week while there, and for 4 consecutive weeks after leaving. The weekly dosage for adults is 300mg base 500mg salt.

    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.

    Chloroquine treatment of antigen-presenting cells APC was explored as a tool to investigate the processing pathway for major histocompatibility complex MHC class II-restricted presentation of the endogenous secreted hen egg lysozyme HEL and transmembrane measles virus haemagglutinin HA. Chloroquine is known to block MHC class II-dependent antigen processing and presentation by affecting lysosomal acidification and invariant chain dissociation from the MHC class II molecules. Continuous treatment with high doses of chloroquine in vivo is an established immunosuppressive therapy for autoimmune diseases. In our proliferative assay in vitro, we found an inhibitory effect by using 20 μM, and some concerns may arise about the dosage of chloroquine that we used in our. This invention provides a pharmaceutical composition which comprises an amount of chloroquine effective to block MHC Class I recycling and an amount of a CD8+ T cell stimulatory agent effective to stimulate proliferation of CD8+ T cells to a concentration such that the resulting CD8+ T cells kill CD4+ T cells, and a pharmaceutically acceptable carrier.
