Transcriptional profiles of CD27 negative and positive MAIT cells from PBMC of diabetic obese patients


ABSTRACT: Our previous observation found CD27 negative MAIT cell subset is associated with T2D progression in overweight/obese patients. To identify the difference of functional properties between CD27 negative and positive MAIT subsets under obesity related T2D condition, we isolated circulating CD27+ or CD27- CD3+ CD161+ TCR Va7.2+ MAIT cells from PBMC of three diabetic obese patients and performed bulk RNA-seq based on Smart-seq2 protocol. By the comparison of CD27- and CD27+ MAIT cells, we found CD27- MAIT cell exhibit an increased mitochondrial mass and decreased response to bacterium transcriptional pattern compared to CD27+ MAIT cells in diabetic obese patients, indicating the imbalanced cell-bacteria interaction might contribute to T2D progression in overiweight/obese people.
