Plasmodium falciparum calcineurin and its association with heat shock protein 90: mechanisms for the antimalarial activity of cyclosporin A and synergism with geldanamycin.

Abstract excerpt

Geldanamycin (GA), an antibiotic of the ansamycin family and an inhibitor of heat shock protein 90 (Hsp90), was previously shown to inhibit the malarial parasite, Plasmodium falciparum. Here we report that cyclosporin A (CsA), an inhibitor of parasitic cyclophilin (Cyp) and protein phosphatase 2B (calcineurin, CN), acted synergistically with GA to inhibit the erythrocytic growth of the parasite. Parasitic...
