Malaria parasites regulate intraerythrocytic development duration via serpentine receptor 10 to coordinate with host rhythms

Project description:The intra-erythrocytic developmental cycle (IDC) of malaria parasites is synchronized with the time-of-day hosts feed, but the mechanism underpinning this coordination is unknown. Combining in vivo and in vitro approaches using rodent and human malaria parasites, we reveal that: (i) 57% of P. chabaudi genes exhibit 24 h “circadian” periodicity in expression; (ii) 58% of these genes lose rhythmicity when the IDC is out-of-synchrony with host rhythms; (iii) 6% of P. falciparum genes show circadian expression under free-running conditions; (iv) Serpentine receptor 10 (SR10) is circadian and disrupting it in rodent models shortens the IDC by 2-3 hours; (v) diverse processes, including DNA replication, the ubiquitin and proteasome pathways, are affected by disruption of SR10 and loss of coordination with host rhythms. Our results reveal that malaria parasites are at least in part responsible for scheduling their IDC, explaining the fitness benefits of coordination with host rhythms.

Malaria parasites regulate intra-erythrocytic development duration via serpentine receptor 10 to coordinate with host rhythms.

Project description:Malaria parasites complete their intra-erythrocytic developmental cycle (IDC) in multiples of 24?h suggesting a circadian basis, but the mechanism controlling this periodicity is unknown. Combining in vivo and in vitro approaches utilizing rodent and human malaria parasites, we reveal that: (i) 57% of Plasmodium chabaudi genes exhibit daily rhythms in transcription; (ii) 58% of these genes lose transcriptional rhythmicity when the IDC is out-of-synchrony with host rhythms; (iii) 6% of Plasmodium falciparum genes show 24?h rhythms in expression under free-running conditions; (iv) Serpentine receptor 10 (SR10) has a 24?h transcriptional rhythm and disrupting it in rodent malaria parasites shortens the IDC by 2-3?h; (v) Multiple processes including DNA replication, and the ubiquitin and proteasome pathways, are affected by loss of coordination with host rhythms and by disruption of SR10. Our results reveal malaria parasites are at least partly responsible for scheduling the IDC and coordinating their development with host daily rhythms.
