Abstract
Histone modifying enzymes have vital roles in the growth and survival of both parasites and humans. Targeting the epigenome can be a new strategy for the treatment of parasitic diseases. Compounds modulating histone acetylation/deacetylation have recently been reported hampering Plasmodium, Schistosoma, Leishmania, and Trypanosoma infections. Beside new histone deacetylase inhibitors, PfGCN5 and bromodomain inhibitors have been recently described to inhibit Plasmodium proliferation. Sm histone deacetylase 8 and SmSIRT2, as well as Leishmania and Trypanosoma sirtuins (SIR2rps), seem to be the most reliable targets to effectively fight the related protozoan infections. The selectivity toward parasite over mammalian cells is still an open question, and significant optimization efforts of epidrugs are still required to improve potency/selectivity and decrease toxicity. Recent reports on the alteration of cellular signaling pathways provoked by parasite infection through changes in the host acetylation/deacetylation status at gene promoters may suggest novel therapeutic strategies to treat these diseases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
