BACKGROUND: Pulmonary tuberculosis (TB) and lung cancer (LC) have similar clinical symptoms and atypical imaging findings which are easily misdiagnosed. There is an urgent need for a noninvasive, rapid and accurate biomarker for distinguishing LC from TB.
For metabolic profiling of human CD4+ T cells，stable isotope labeling (SIL) and metabolomics SIL experiments were performed with in vitro-activated T cells using liquid chromatography (LC) coupled to mass spectrometry (MS).
For metabolic profiling of mouse CD4+ T cells, stable isotope labeling (SIL) experiments were performed with in vitro-activated T cells using gas chromatography (GC) coupled to mass spectrometry (MS).
