In vivo stable isotope labeling protocols. (a) Long-term ²H₂O administration. ²H₂O was given daily for 9 weeks after a priming regimen. T cells and monocytes/granulocytes were sampled at times shown. Urine and saliva were sampled as shown, to measure body ²H₂O enrichment. (b) ²H₂-glucose incorporation/die-away curves. ²H₂-glucose was given over 48 hours with follow-up blood draws for T cells as shown. Blood glucose enrichments were measured during the i.v. ²H₂-glucose infusion. Mono/granulo, monocytes/granulocytes; Glc, glucose. Arrows indicate times of stable isotope label administration or sample collection.
