CO:SAMPLE_TYPE T-cells CO:STORAGE_CONDITIONS -80℃ #TREATMENT TR:TREATMENT_SUMMARY For Th17 cell differentiation, isolated CD4+ cells were activated with a TR:TREATMENT_SUMMARY combination of plate-bound anti-CD3 (750 ng/24-well culture plate well; TR:TREATMENT_SUMMARY Immunotech/Beckman Coulter REF # IM-1304) and soluble anti-CD28 ((1ug/mL; TR:TREATMENT_SUMMARY Immunotech/Beckman coulter REF # IM1376) antibodies in serum-free X-Vivo 20 TR:TREATMENT_SUMMARY medium (Lonza), in the absence (Th0) or presence (Th17) of IL-6 (20ng/ml, Roche, TR:TREATMENT_SUMMARY Cat# 11138600 001); IL-1β (10ng/ml, R&D Systems Cat # 201 LB); TGF-β1 TR:TREATMENT_SUMMARY (10ng/ml, R&D Systems Cat# 240); anti-IL-4 (1 g/ml) R&D Systems Cat# MAB204) TR:TREATMENT_SUMMARY and anti-IFN-γ (1 μg/ml R&D Systems Cat#MAB-285). Differentiation of Th17 TR:TREATMENT_SUMMARY cells was confirmed by measuring IL-17 expression by quantitative real-time PCR, TR:TREATMENT_SUMMARY at 72 hours of Th17 / Th0 culturing. For iTreg cell culturing, after of CD25+ TR:TREATMENT_SUMMARY cells, done using LD columns and a CD25 depletion kit (Miltenyi Biotec), TR:TREATMENT_SUMMARY CD4+CD25− cells were activated with plate-bound anti-CD3 (500 ng/24-well TR:TREATMENT_SUMMARY culture plate well) and soluble anti-CD28 (500 ng/mL) at a density of 2 × 106 TR:TREATMENT_SUMMARY cells/mL of X-vivo 15 serum-free medium (Lonza). For iTreg differentiation, the TR:TREATMENT_SUMMARY medium was supplemented with IL-2 (12 ng/mL), TGF-β (10 ng/mL) (both from R&D TR:TREATMENT_SUMMARY Systems), all-trans retinoic acid (ATRA) (10 nM; Sigma-Aldrich), and human serum TR:TREATMENT_SUMMARY (10%) and cultured at 37°C in 5% CO2. Control Th0 cells were stimulated with TR:TREATMENT_SUMMARY plate-bound anti-CD3 soluble anti-CD28 antibodies without cytokines. For TR:TREATMENT_SUMMARY confirmation of iTreg cell differentiation, we used intracellular staining to TR:TREATMENT_SUMMARY measure, at 72 hours of iTreg culturing, expression of FOXP3 which is the major TR:TREATMENT_SUMMARY transcription factor driving Treg differentiation. Intracellular staining was TR:TREATMENT_SUMMARY performed using buffer sets of Human Regulatory T-cell Staining Kit TR:TREATMENT_SUMMARY (eBioscience/Thermo Fisher Scientific), following the manufacturer’s protocol. TR:TREATMENT_SUMMARY The following antibodies were used: anti-human FOXP3-PE (eBioscience, Cat. No. TR:TREATMENT_SUMMARY 12-4776-42) and rat IgG2a isotype control (eBioscience, Cat. No. 72-4321-77A). TR:TREATMENT_SUMMARY All samples were acquired by a flow cytometer (LSRII) and analyzed either with TR:TREATMENT_SUMMARY FlowJo (FLOWJO, LLC) or with Flowing Software. For Th1 and Th2 cells, purified TR:TREATMENT_SUMMARY naive CD4+ T-cells were activated with plate-bound anti-CD3 (500 ng/24-well TR:TREATMENT_SUMMARY culture plate well) and 500 ng/ml soluble anti-CD28 and cultured in the absence TR:TREATMENT_SUMMARY (Th0) or presence of 2.5 ng/ml IL-12 (R&D Systems) (Th1) or 10 ng/ml IL-4 (R&D TR:TREATMENT_SUMMARY Systems) (for Th2). At 48 hours following the activation of the cells, 17 ng/ml TR:TREATMENT_SUMMARY IL-2 (R&D Systems) was added to the cultures. Differentiation of Th1 and Th2 TR:TREATMENT_SUMMARY cells was confirmed by measuring (using flow cytometry) the expression of T-bet TR:TREATMENT_SUMMARY and Gata3 at 72 hours after cell activation. Briefly, cells were fixed and TR:TREATMENT_SUMMARY permeabilized using the Intracellular Fixation & Permeabilization Buffer Set TR:TREATMENT_SUMMARY (eBioscience / Thermo Fisher Scientific), according the manufacturer’s TR:TREATMENT_SUMMARY protocol. The following antibodies were used: anti-human GATA3-PE (eBioscience, TR:TREATMENT_SUMMARY 12-9966), anti-human T-bet-BV711 (BD, 563320) and corresponding isotype controls TR:TREATMENT_SUMMARY (BV711 Mouse IgG1, BD, 563044 and PE Rat IgG2b, eBioscience, 12-4031-82). TR:TREATMENT_SUMMARY Samples were acquired by BD LSRFortessa™ cell analyzer and data were analyzed TR:TREATMENT_SUMMARY using FlowJo software (FLOWJO, LLC). #SAMPLEPREP SP:SAMPLEPREP_SUMMARY The frozen cell preps were defrosted on ice. The samples were extracted using a SP:SAMPLEPREP_SUMMARY modified Folch method[1]. 1. Sen, P. et al.

Clin Transl Gastroenterol 10, 1-10, SP:SAMPLEPREP_SUMMARY doi:10.14309/ctg.0000000000000044 (2019). Briefly, 120 µL of cold (4 °C) SP:SAMPLEPREP_SUMMARY extraction solvent (CHCl3: MeOH, (2:1 v/v) was added to the samples. The SP:SAMPLEPREP_SUMMARY extraction solvent containing the following internal standards: C17 SP:SAMPLEPREP_SUMMARY Lactosyl(beta) ceramide (D18:1/17:0, 20 ppb), C17 Glucosyl(beta) ceramide SP:SAMPLEPREP_SUMMARY (D18:1/17:0, 20 ppb), C17 ceramide (D18:1/17:0, 20 ppb), C16 ceramide-d7 SP:SAMPLEPREP_SUMMARY (d18:1-d7/16:0, 16,57 ppb), C18 ceramide-d7 (d18:1-d7/18:0, 8.75 ppb), C24 SP:SAMPLEPREP_SUMMARY ceramide-d7 (d18:1-d7/24:0, 20 ppb), and C24:1 ceramide-d7 (d18:1-d7/24:1(15Z), SP:SAMPLEPREP_SUMMARY 9,96 ppb). The samples were the vortexed briefly and left on ice for 30 minutes. SP:SAMPLEPREP_SUMMARY The samples were then centrifuged (9400g, 5 min, 4 °C) and then 60 µL of the SP:SAMPLEPREP_SUMMARY bottom layer was transfer to a clean mass spectrometry vial (2 mL). The samples SP:SAMPLEPREP_SUMMARY were then stored at –80 °C. SP:PROCESSING_STORAGE_CONDITIONS -80℃ SP:EXTRACT_STORAGE -80℃ #CHROMATOGRAPHY CH:CHROMATOGRAPHY_SUMMARY Chromatographic separation was performed on an ACQUITY UHPLC BEH C18 column (2.1 CH:CHROMATOGRAPHY_SUMMARY mm × 100 mm, particle size 1.7 µm, Waters, Milford, MA, USA). The flow rate CH:CHROMATOGRAPHY_SUMMARY was set at 0.4 ml/min throughout the run with an injection volume of 1 µL. The CH:CHROMATOGRAPHY_SUMMARY following solvents were used for the gradient elution: Solvent A was H2O with 1% CH:CHROMATOGRAPHY_SUMMARY NH4Ac (1M) and HCOOH (0.1%) added. Solvent B was a mixture of ACN: IPA (1:1 v/v) CH:CHROMATOGRAPHY_SUMMARY with 1% NH4Ac (1M) and HCOOH (0.1%) added. The gradient was programmed as CH:CHROMATOGRAPHY_SUMMARY follows: 0 to 2 min 35-80% B, 2 to 7 min 80-100 % B, 7 to 14 min 100% B. The CH:CHROMATOGRAPHY_SUMMARY column was equilibrated with a 7min period of 35 % B prior to the next run. CH:CHROMATOGRAPHY_TYPE None (Direct infusion) CH:INSTRUMENT_NAME Waters Acquity UHPLC UNSPSC 41115709 CH:COLUMN_NAME Waters BEH C18 (2.1 mm × 100 mm, 1.7 µm ) #ANALYSIS AN:ANALYSIS_TYPE MS #MS MS:INSTRUMENT_NAME ABI Sciex 5500 QTrap MS:INSTRUMENT_TYPE Triple quadrupole MS:MS_TYPE ESI MS:ION_MODE POSITIVE MS:MS_COMMENTS The ceramides were quantified using a targeted multiple reaction monitoring MS:MS_COMMENTS (MRM) method using UHPLC as a separation technique. The LC separation was based MS:MS_COMMENTS on the global lipidomics method previously described 71. Briefly, the UHPLC was MS:MS_COMMENTS a Exion AD (Sciex) integrated system. The samples were held in a cool box at 15 MS:MS_COMMENTS °C prior to the analysis. The needle was washed with both a 10% DCM in MeOH and MS:MS_COMMENTS ACN: MeOH: IPA: H2O (1:1:1:1 v/v/v/v) with 1% HCOOH for a total of 7.5 seconds MS:MS_COMMENTS each. The solvents were delivered using a quaternary solvent and a column oven MS:MS_COMMENTS (set to 50 °C). The separation was performed on an ACQUITY UHPLC BEH C18 column MS:MS_COMMENTS (2.1 mm × 100 mm, particle size 1.7 µm, Waters, Milford, MA, USA). The flow MS:MS_COMMENTS rate was set at 0.4 ml/min throughout the run with an injection volume of 1 µL. MS:MS_COMMENTS The following solvents were used for the gradient elution: Solvent A was H2O MS:MS_COMMENTS with 1% NH4Ac (1M) and HCOOH (0.1%) added. Solvent B was a mixture of ACN: IPA MS:MS_COMMENTS (1:1 v/v) with 1% NH4Ac (1M) and HCOOH (0.1%) added. The gradient was programmed MS:MS_COMMENTS as follows: 0 to 2 min 35-80% B, 2 to 7 min 80-100 % B, 7 to 14 min 100% B. The MS:MS_COMMENTS column was equilibrated with a 7min period of 35 % B prior to the next run. The MS:MS_COMMENTS mass spectrometer was a Sciex 5500 QTRAP (Sciex) set in scheduled MRM mode. All MS:MS_COMMENTS lipids were identified for their fatty acid composition by MS/MS to confirm MS:MS_COMMENTS their exact identification, there was also a linear relationship between the MS:MS_COMMENTS increasing number of carbons in the lipid chain and its corresponding retention MS:MS_COMMENTS time. Due to the isobaric nature of sugars we were unable to differentiate Glc MS:MS_COMMENTS and Glc head groups. All data were integrated using the quantitation tool in MS:MS_COMMENTS MultiQuant (3.0.3), all peaks were manually checked. Any analytes which were MS:MS_COMMENTS over the concentration of the standard curve were diluted (1:25) with the same MS:MS_COMMENTS extraction solvent minus the internal standards. The quantification was MS:MS_COMMENTS performed using class-based internal standards and in the case of those ceramide MS:MS_COMMENTS species without an authentic standard in the standard curve mix, we used the MS:MS_COMMENTS closest related structure. The standard curve mixture contained: Glucosyl (beta) MS:MS_COMMENTS C12 ceramide, Lactosyl (beta)) C12 ceramide, C18 ceramide (D18:1/18:1), C18:1 MS:MS_COMMENTS dihydroceramide (d18:0/18:1(9Z)) and was run at the following levels (all in MS:MS_COMMENTS ppb): 100, 80, 60, 50, 40, 30, 20, 10 for the C12 standards and 10, 8, 6, 5, 4, MS:MS_COMMENTS 3, 2,1 for all C18 standards. #MS_METABOLITE_DATA MS_METABOLITE_DATA:UNITS ng/ml MS_METABOLITE_DATA_START Samples Th0(iTreg)_D1 Th0(iTreg)_D2 Th0(iTreg)_D3 Th0(iTreg)_D4 Th0(iTreg)_D5 iTreg_D1 iTreg_D2 iTreg_D3 iTreg_D4 iTreg_D5 Th0(Th17)_D1 Th0(Th17)_D2 Th0(Th17)_D3 Th0(Th17)_D4 Th17_D1 Th17_D2 Th17_D3 Th17_D4 Factors Cell Type:Th0(iTreg) | Treatment:Activated | Types:Control Cell Type:Th0(iTreg) | Treatment:Activated | Types:Control Cell Type:Th0(iTreg) | Treatment:Activated | Types:Control Cell Type:Th0(iTreg) | Treatment:Activated | Types:Control Cell Type:Th0(iTreg) | Treatment:Activated | Types:Control Cell Type:iTreg | Treatment:Differentiated | Types:Test Cell Type:iTreg | Treatment:Differentiated | Types:Test Cell Type:iTreg | Treatment:Differentiated | Types:Test Cell Type:iTreg | Treatment:Differentiated | Types:Test Cell Type:iTreg | Treatment:Differentiated | Types:Test Cell Type:Th0(Th17) | Treatment:Activated | Types:Control Cell Type:Th0(Th17) | Treatment:Activated | Types:Control Cell Type:Th0(Th17) | Treatment:Activated | Types:Control Cell Type:Th0(Th17) | Treatment:Activated | Types:Control Cell Type:Th17 | Treatment:Differentiated | Types:Test Cell Type:Th17 | Treatment:Differentiated | Types:Test Cell Type:Th17 | Treatment:Differentiated | Types:Test Cell Type:Th17 | Treatment:Differentiated | Types:Test Cer(d18:1/16:0) 1012.68546 672.5494055 1631.038852 1537.40139 1073.526994 916.4161778 783.3895333 644.6994082 889.0454995 1183.612282 1208.987674 1848.090598 1644.234001 1456.22755 1917.596306 1912.59949 2076.177883 2188.877779 Cer(d18:1/18:0) 31.69998438 10.04107875 53.17793096 52.27437215 33.03001516 47.04793078 51.48829384 22.72753944 48.84327948 97.8365176 58.79365442 89.06153928 80.98723773 70.31469624 128.0916673 135.5119388 130.6323193 144.4103987 Cer(d18:1/22:0) 146.8803686 79.27945659 178.6916896 192.9223662 138.4886749 199.7196865 174.300044 137.2307164 196.9364765 333.3164142 220.6288519 281.5388831 273.4716788 267.7221615 511.4423771 495.4775507 515.482932 565.4313422 Cer(d18:1/24:0) 389.9305013 210.2873494 538.0923199 603.7689079 422.4158359 1315.084264 1031.852612 946.4647354 1119.840092 1563.642477 697.6888838 944.5164007 885.3253591 889.3057942 1572.741065 1532.666602 1634.471765 1737.323141 Cer(d18:1/26:1) 10893.66635 4235.090247 6198.326337 22730.32735 9883.455612 23635.40418 14628.23588 48677.5029 13252.17558 33515.65859 8789.125064 12176.83632 12668.11377 7793.209188 37202.96873 34783.51404 37093.47208 39108.8451 HexCer(d18:1/16:0) 4031.586022 3503.966047 5368.640756 7986.347601 7750.515976 2197.621821 2068.408245 2292.54935 2028.447511 3041.60717 1885.585176 2586.797903 2342.261604 2478.32475 1289.857153 1431.209071 1539.770104 1476.422491 HexCer(d18:1/20:0) 228.2426075 159.6416653 272.9560419 353.3709547 409.6404729 18.26133503 10.44904789 22.64885251 18.55392972 75.9638476 90.01387958 125.7012623 120.9382479 140.6283528 67.56533389 83.08068558 100.0313345 86.13351254 HexCer(d18:1/22:0) 1406.418011 1246.166375 1715.332054 2160.890026 2042.927942 703.5393285 599.0440639 697.7010111 691.2897683 1072.80511 1048.024154 1134.183196 1229.914552 1429.282002 880.9766155 956.2313041 1045.014513 923.3870968 HexCer(d18:1/24:0) 1847.446237 1563.979819 2828.495808 3605.86386 2915.628344 3638.764382 3529.278992 3551.376184 3414.103204 5172.673136 2069.050924 2236.166767 2325.407861 2782.308729 1446.449699 1572.69181 1580.999736 1588.429659 HexCer(d18:1/24:1) 1987.455197 1537.495365 2988.36507 4159.119607 3692.777608 2385.852686 2123.61557 2362.762799 2367.933156 3744.750763 1079.93124 1200.970079 1238.341423 1536.570465 793.9807565 816.7697469 913.0796886 860.3830645 LacCer(d18:1/16:0) 1630.206593 1197.092313 2273.354913 1812.377691 1398.889882 2104.123133 1990.926258 2054.724746 2046.435071 2133.826934 2283.675799 2862.578361 2785.800904 2741.743115 4793.288873 5511.949178 4789.46175 5233.328886 MS_METABOLITE_DATA_END #METABOLITES METABOLITES_START metabolite_name PubChem ID KEGG ID Cer(d18:1/16:0) Cer(d18:1/18:0) Cer(d18:1/22:0) Cer(d18:1/24:0) Cer(d18:1/26:1) HexCer(d18:1/16:0) HexCer(d18:1/20:0) HexCer(d18:1/22:0) HexCer(d18:1/24:0) HexCer(d18:1/24:1) LacCer(d18:1/16:0) METABOLITES_END #END
