For instance, PR:PROJECT_SUMMARY maturation can be influenced by host nutrient status or circadian rhythm. Here PR:PROJECT_SUMMARY we observed in mice that systemic host inflammation, induced by PR:PROJECT_SUMMARY lipopolysaccharide (LPS) conditioning or ongoing acute malaria infection, slowed PR:PROJECT_SUMMARY the progression of a single cohort of parasites from one generation of RBC to PR:PROJECT_SUMMARY the next. LPS-conditioning and acute infection both triggered substantial PR:PROJECT_SUMMARY changes to the metabolomic composition of plasma in which parasites circulated. PR:PROJECT_SUMMARY This altered plasma directly slowed parasite maturation in a manner that could PR:PROJECT_SUMMARY not be rescued by supplementation, consistent with the presence of inhibitory PR:PROJECT_SUMMARY factors. Single-cell transcriptomic assessment of mixed parasite populations, PR:PROJECT_SUMMARY exposed to a short period of systemic host inflammation in vivo, revealed PR:PROJECT_SUMMARY specific impairment in the transcriptional activity and translational capacity PR:PROJECT_SUMMARY of trophozoites compared to rings or schizonts.

Mice were euthanized by CO2 asphyxiation and their CO:COLLECTION_SUMMARY blood was taken by cardiac puncture into lithium-heparin coated tubes. Samples CO:COLLECTION_SUMMARY were spun for 5 min at 5000 rpm (approx. 7,043 × g) and plasma was immediately CO:COLLECTION_SUMMARY aliquoted into 1.5 mL tubes. In addition, a global sample pool containing equal CO:COLLECTION_SUMMARY volumes of each sample was prepared as quality control (QC) and four aliquots CO:COLLECTION_SUMMARY were transferred into 1.5 mL tubes. Finally, collection tube blank extractions CO:COLLECTION_SUMMARY were performed in triplicate by adding 1x PBS (same volume as blood collection) CO:COLLECTION_SUMMARY to lithium-heparin tubes and then transferring an aliquot into a 1.5 mL tube CO:SAMPLE_TYPE Blood (plasma) #TREATMENT TR:TREATMENT_SUMMARY Genotype: Treatment C57BL/6J Naïve: Control, C57BL/6J mice were TR:TREATMENT_SUMMARY intraperitoneally injected (200 uL) with saline (0.9%) 9 hours prior to plasma TR:TREATMENT_SUMMARY acquisition. C57BL/6J Acute: Infected, C57BL/6J mice were infected with 10^5 TR:TREATMENT_SUMMARY Plasmodium berghei ANKA parasitised red blood cells 5 days prior to plasma TR:TREATMENT_SUMMARY acquisition and intraperitoneally injected (200 uL) with saline (0.9%) 9 hours TR:TREATMENT_SUMMARY prior to plasma acquisition for analysis. C57BL/6J LPS: LPS treatment, C57BL/6J TR:TREATMENT_SUMMARY mice were intraperitoneally injected (200 uL) with lipopolysaccharides (LPS) TR:TREATMENT_SUMMARY (0.75 mg/mL), from E.coli O127:B8, 9 hours prior to plasma acquisition. rag1-/- TR:TREATMENT_SUMMARY Naïve: Immune deficient control, C57BL/6J.rag1-/- mice were intraperitoneally TR:TREATMENT_SUMMARY injected (200 uL) with saline (0.9%) 9 hours prior to plasma acquisition. TR:TREATMENT_SUMMARY rag1-/- Acute: Immune deficient infected control, C57BL/6J.rag1-/- mice were TR:TREATMENT_SUMMARY infected with 10^5 Plasmodium berghei ANKA parasitised red blood cells 5 days TR:TREATMENT_SUMMARY prior to plasma acquisition and intraperitoneally injected (200 uL) with saline TR:TREATMENT_SUMMARY 9 hours prior to plasma acquisition for analysis. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Ten-times the sample volume of ice-cold butanol/methanol (1:1) containing 50 SP:SAMPLEPREP_SUMMARY µg/mL antioxidant 2,6-di-tert-butyl-4-methylphenol (BHT) was added to each SP:SAMPLEPREP_SUMMARY sample and vortexed for 10 s. Samples were snap frozen and transported on dry SP:SAMPLEPREP_SUMMARY ice. Subsequently, samples were thawed on ice and labelled in a randomized SP:SAMPLEPREP_SUMMARY order. Samples were sonicated for 15 min in an ice-cold water bath sonicator, SP:SAMPLEPREP_SUMMARY stored for 2 hrs at -30oC and then centrifuged for 15 min at 16,000 × g (4oC). SP:SAMPLEPREP_SUMMARY Lastly, samples were aliquoted, dried down using a vacuum concentrator and SP:SAMPLEPREP_SUMMARY stored at -80oC until LC/MS analysis #CHROMATOGRAPHY CH:CHROMATOGRAPHY_SUMMARY Metabolite separation was performed on a Zorbax HILIC Plus RRHD (95Å, 1.8 µm, CH:CHROMATOGRAPHY_SUMMARY 2.1x100mm) analytical column connected to a 3 x 5 mm Zorbax HILIC Plus UHPLC CH:CHROMATOGRAPHY_SUMMARY guard column. The autosampler and column temperature were set to 4°C and 40°C, CH:CHROMATOGRAPHY_SUMMARY respectively. In positive and negative mode, eluent A was 10 mM ammonium acetate CH:CHROMATOGRAPHY_SUMMARY (pH neutral) in acetonitrile/milliQ water (95:5, v/v) and eluent B was 10 mM CH:CHROMATOGRAPHY_SUMMARY ammonium acetate (pH neutral) in acetonitrile/milliQ water (50:50, v/v). Total CH:CHROMATOGRAPHY_SUMMARY method runtime was 12 min with the following gradient for both modes: 0 min (1% CH:CHROMATOGRAPHY_SUMMARY eluent B) - 3.5 min (50% B) - 5.5 min (99%B) - 6.5 min (99% B) - 6.7 min (1% B) CH:CHROMATOGRAPHY_SUMMARY - 12 min (1% B). Flow rate was set to 0.5 mL/min. CH:CHROMATOGRAPHY_TYPE HILIC CH:INSTRUMENT_NAME Agilent 1290 Infinity II CH:COLUMN_NAME Agilent Zorbax HILIC Plus RRHD (95Å, 1.8 µm, 2.1x100mm) #ANALYSIS AN:ANALYSIS_TYPE MS #MS MS:INSTRUMENT_NAME Agilent 6545 QTOF MS:INSTRUMENT_TYPE QTOF MS:MS_TYPE ESI MS:ION_MODE NEGATIVE MS:MS_COMMENTS MS acquisition: The LC/MS platform consisted of a 1290 Infinity II UHPLC coupled MS:MS_COMMENTS to a 6545 QTOF mass spectrometer via Dual AJS ESI source (Agilent, Santa Clara, MS:MS_COMMENTS USA) and was controlled using MassHunter data acquisition software (v.10.1). MS:MS_COMMENTS Assessment of MS instrument performance and usage of reference ions were also MS:MS_COMMENTS performed as described previously. Full scan MS data (m/z 50-1700) was acquired MS:MS_COMMENTS at a scan rate of 2.5 spectra/sec (equals 3224 transients/spectrum) with the MS:MS_COMMENTS following source conditions: Gas temperature 250°C, gas flow 13 L/min, sheath MS:MS_COMMENTS gas temperature and flow at 400°C and 12 L/min, respectively, nebulizer 30 psi, MS:MS_COMMENTS fragmentor 135, capillary voltage at +4500 V and -4000 V, nozzle voltage was MS:MS_COMMENTS zero. Data processing: Positive and negative mode data was analysed separately. MS:MS_COMMENTS Data files (30 sample files, 6 QC files and 3 tube blank extraction files) were MS:MS_COMMENTS loaded into MassHunter Profinder (v 10 SP1, Agilent) and assigned to sample MS:MS_COMMENTS groups. Spectral feature extraction was performed using the recursive feature MS:MS_COMMENTS extraction method employing default settings with minor adjustments: Peak MS:MS_COMMENTS extraction was restricted to retention time (Rt) range 0-6.5 min, compound MS:MS_COMMENTS binning and alignment tolerances were set to 1% + 0.3 min for Rt and 20 ppm + 2 MS:MS_COMMENTS mDa for mass, integrator Agile 2 was used for peak integration, peak filters MS:MS_COMMENTS were set to at least 2500 counts and features must have satisfied filter MS:MS_COMMENTS conditions in at least 75 % of files in at least one sample group. Feature peak MS:MS_COMMENTS area was exported and data cleaning was performed using an in-house R script MS:MS_COMMENTS compiled of the following steps. Features were deleted if they: had a mean MS:MS_COMMENTS QC/tube blank area ratio of < 10; were absent across all QC samples; and had MS:MS_COMMENTS duplicates present. In addition, samples with a TIC scaling factor more than 50% MS:MS_COMMENTS above or below the median TIC were removed.
