Specifically, exogenous C16-ceramide enhanced parasite development and nuclear replication, while sphingomyelin in the host cell membrane was essential for parasite invasion. Live microscopy studies using NBD labeled sphingolipids further found that exogenous lipids are actively transported into the PV with sphingolipid scavenging occurring at all tested time points throughout the liver stage. This was, in part, supported by the host ceramide transporter, CERT1. CERT1 was enriched at the PV and genetic disruption significantly reduced both\n                      <jats:italic toggle=\"yes\">P. berghei<\/jats:italic>\n                      load and ceramide trafficking into the PV.

Despite the existence of antimalarial treatments, the emergence of drug-resistant parasites highlights the urgent need to identify novel therapeutic targets. The\n                        <jats:italic toggle=\"yes\">Plasmodium<\/jats:italic>\n                        liver stage represents a promising avenue for drug discovery as inhibiting parasite development would prevent both symptomatic disease and transmission to the mosquito vector. In this study, we examined the role of host sphingolipids and found that members perform distinct functions, supporting parasite invasion and\/or development. We also identified several host proteins that influence\n                        <jats:italic toggle=\"yes\">Plasmodium<\/jats:italic>\n                        liver stage viability and contribute to sphingolipid acquisition.
