Study TitleMetabolomic study of T effector and T regulatory cells in severe allergic patients
Study SummaryMetabolism has a profound impact on T cell fate and function. Uncovering the metabolome of circulating human CD4+ T effector memory (Teff) and T regulatory (Treg) cells would enable better understanding of Th2-driven diseases, such as allergy or asthma. Here, we demonstrated that in healthy humans, energy metabolism and functions of memory CD4+ Teff cells mainly relied on amino acids, whereas Treg cells predominantly used fatty acids. Arginine and phenylalanine increased T cell receptorinduced glycolysis and oxidative phosphorylation in total and memory CD4+ T cells, but high levels of phenylalanine limited CD4+ T cell proliferation via disrupting mitochondrial respiration and activation of L-phenylalanine oxidase, IL4I1. Accordingly, lowest levels of phenylalanine were linked with the pathogenic Th2a cells, and impaired Treg cells in patients with the most severe forms of allergies. It all suggests that phenylalanine is a metabolic checkpoint of pathogenic Th2 cells development.

Collection:

Collection ID:CO003245
Collection Summary:Whole blood was drawn from the participants into heparin tubes and serum in silica tubes. Next, PBMCs were isolated using Ficoll Plaque by gradient density centrifugation according to manufacturer instructions. Isolated PMBCs were then immediately frozen and kept at -80˚C until analysis. Teff and Treg cell subpopulations were determined through FlowJo X (v.10.7.1.) and FlowSOM (v.2.6).
Sample Type:Blood (whole)
Storage Conditions:-80℃

Treatment:

Treatment ID:TR003261
Treatment Summary:After cell sorting, the only treatment received was the addition of a volume of 50 uL of MeOH to each sample and then cells were frozen at -80 ºC until metabolomics and lipidomic analysis.

Sample Preparation:

Sampleprep ID:SP003259
Sampleprep Summary:Frozen cells in MeOH were thawed at 4˚C. Then a first extraction targeted at lipid metabolites was performed by adding MTBE to a final concentration of MTBE: MeOH (1:4). Samples were then sonicated for a total of 15 min at 15W (3 rounds of 5 min sonication), thoroughly vortexed, and centrifuged for 10 min at 16000 g to remove any debris. The supernatant was collected. Then a second extraction took place to obtain the most polar metabolites in the sample. To that extent, 100 μl of a mixture of H2O:MeOH (1:4) was added and the sample was sonicated again for a total of 15 min at 15W (3 rounds of 5 min sonication), thoroughly vortexed and centrifuged for 10 min at 16000 g to remove any debris. The supernatant was collected. Polar samples were kept at 4 degrees until their analysis. Extraction solvents were used as a blank and followed the same procedure as the samples. Quality control (QC) samples were prepared by pooling equal volumes of samples from the same cell type separately. Additionally, to select features produced only by cells, a calibration curve was made of Teff or Treg cells, respectively. Samples were divided into 2 groups depending on the type of subpopulation they belong to either Teff or Treg, and randomized.

Chromatography:

Chromatography ID:CH003895
Chromatography Summary:For polar metabolites separation, 2 μL of the sample were injected into a Zorbax Extend C18 (4.6 × 50 mm, 1.8 μm; Agilent, Waldbronn, Germany), with a guard column Zorbax Extend C18 (3 × 5 mm, 1.8 μm; Agilent), both maintained at 60 °C. The flow rate was set at 0.6 mL/min. The elution gradient involved a mobile phase consisting of: (A) water containing 0.1% of formic acid and (B) acetonitrile containing 0.1% of formic acid. The initial conditions were set at 5% phase B for 1 min, which increased linearly to 80% phase B in 7 min. Then in 4.5 min it increased until 100% of phase. Then the equipment returned to the initial conditions in 0.5 min, which were held for 3 min for column reconditioning.

Chromatography Summary:For the lipidic extraction, the Agilent 1290 Infinity II Multisampler system, equipped with a multi-wash option, was used to uptake 1 and 2 µL of extracted samples in positive and negative ionization modes, respectively. The multisampler temperature was maintained at 15 °C to preserve lipids in a stable environment and avoid precipitation. An Agilent InfinityLab Poroshell 120 ECsingle bondC18 (3.0 × 100 mm, 2.7 µm) (Agilent Technologies) column and a compatible guard column (Agilent InfinityLab Poroshell 120 ECsingle bondC18, 3.0 × 5 mm, 2.7 µm) were used and maintained at 50 °C. The chromatography gradient started at 70% of B at 0 – 1 min, 86% at 3.5 – 10 min, 100% B at 11–17 min. The starting conditions were recovered by minute 17, followed by a 2 min re-equilibration time; the total running time was 19 min. The mobile phases used for both positive and negative ionization modes consisted of (A) 10 mM ammonium acetate, 0.2 mM ammonium fluoride in 9:1 water/methanol and (B) 10 mM ammonium acetate, 0.2 mM ammonium fluoride in 2:3:5 acetonitrile/methanol/isopropanol. The flow rate was held constant, set at 0.6 mL/min. The multi-wash strategy consisted of a mixture of methanol:isopropanol (50:50, v/v) with the wash time set at 15 s, and aqueous phase:organic phase (30:70, v/v) mixture to assist in the starting conditions.
