Transcriptional profiling of Regulatory T cells isolated from mice exposed to Smoke, Morphine and Smoke plus Morphine

Purpose: The goals of this study were to identify gene expression signatures that are unique to Tregs from mice upon treatments with smoke, morphine and smoke plus morphine Methods and results: Wild-type mice were treated with cigarette smoke (SM) for a period of eight weeks, and/or the chronic continuous administration of morphine (M) via mini-pumps for the final four weeks CD4+CD25highCD127low Tregs from spleen were purified by cell sorting to generate mRNA transcription. Transcriptional profiling revealed a unique Treg signatures in SM, M or SM + M relative to control mice. Conclusion: Our study represents the first detailed analysis of splenic Treg transcriptome in mice exposure to smoke plus morphine. Overall design: Spleen treg mRNA profiles of mice treated with smoke, morphine, or smoke plus morphine.
