Subject Type:	Cultured cells
Subject Species:	Mus musculus
Taxonomy ID:	10090
Genotype Strain:	Fbxo7LacZ mice (Fbxo7tm1a(EUCOMM)Hmgu on a C57BL/6J background) were bred as heterozygous crosses
Age Or Age Range:	WT, heterozygous and homozygous littermates were harvested between 6-9 weeks.
Gender:	Male and female
Subject Comments:	All experiments in mice were performed in accordance with the UK Animals (Scientific Procedures) Act 1986 and ARRIVE guidelines. Animal licences were approved by the Home Office and the University of Cambridge's Animal Welfare & Ethical Review Body Standing Committee. Experiments were performed under Home Office licence PPL 70/9001.

Treatment:

Treatment ID:	TR002079
Treatment Summary:	To activate, cells were added to plates coated with 2 µg/mL α-CD3 (clone 145-2C11) and containing 2 µg/mL soluble α-CD28 (clone 37.51) and incubated for the indicated duration. Cell viability and activation were measured by flow cytometry by staining with antibodies to CD4-PE (clone GK1.5), CD25-PE/Cy7 (clone PC61), CD69-FITC (clone H1.2F3) and an eFluor™ 780 fixable viability dye (eBioscience) for 30 min at 4oC in the dark. Samples were analysed on a CytoFLEX S flow cytometer. For metabolite profiling (Fig. 4C & Supplementary Fig. 3C), murine CD4+ T cells were isolated and activated in a 12 well plate for 48 hours. For 13C stable isotope tracing (Fig. 4D), murine CD4+ T cells were isolated and activated in a 12 well plate with culture media containing 2g/L D-Glucose-1,2-13C2 (Sigma) for 24 hours.
