K1 T cells K1 Células T K1 Nicotinamide adenine dinucleotide K1 Nicotinamida adenina dinucleótido AB CD4+ CD25+ Foxp3+ Tregs have been shown to play a central role in immune homeostasis whilepreventing from fatal inflammatory responses, while Th17 cells have traditionally been recognizedas pro-inflammatory mediators implicated in a myriad of diseases. Studies have shown the potentialof Tregs to convert into Th17 cells, and Th17 cells into Tregs. Increasing evidence have pointed outCD25 as a key molecule during this transdifferentiation process, however molecules that allow suchdevelopment remain unknown. Here, we investigated the impact of NAD+ on the fate of CD4+ CD25+Foxp3+ Tregs in-depth, dissected their transcriptional signature profile and explored mechanismsunderlying their conversion into IL-17A producing cells. Our results demonstrate that NAD+ promotesTreg conversion into Th17 cells in vitro and in vivo via CD25 cell surface marker. Despite the reducednumber of Tregs, known to promote homeostasis, and an increased number of pro-inflammatoryTh17 cells, NAD+ was able to promote an impressive allograft survival through a robust systemicIL-10 production that was CD4+ CD25+ Foxp3+ independent. Collectively, our study unravels a novelimmunoregulatory mechanism of NAD+ that regulates Tregs fate while promoting allograft survivalthat may have clinical applications in alloimmunity and in a wide spectrum of inflammatory conditions.
