CD73+ memory CD4 T cells are a long-lived population with elevated effector function and prone to differentiate into TRM-like cells [RNA-seq]

Project description:The understanding of heterogeneity of human memory T cells will help to know the function, development and maintenance of memory population, then to improve the recall response or effective immunotherapy. Ecto-5’-nucleotidase CD73 expression in four subsets of memory T cells decreases with aging. The resistance to apoptosis and high expression of IL7R entitle CD73+ memory T cells to be long-lived population. We found antigen-specific memory T cells have overwhelming CD73 expression. The transcriptional and chromatin accessibility profiles indicate the elevated effector functions in CD73+ memory CD4 T cells comparing to CD73- counterparts. Homer analysis and Transcriptional factor (TF)-regulatory element-target gene triplet network clearly show the crucial role of RUNT and NR family TFs in CD73+ cells. Furthermore, CD73+ memory CD4 T cells were prone to differentiate into TRM-like cells under in-vitro sequential TCR and TGF/IL-15 signaling. The decreased percentage of CD73+ memory T cells with age leads to the less replenishment of TRM cells from peripheral blood.

Expression data from CD73 positive adipose derived mesenchymal stem cells (CD73+ AD-MSCs) and CD73 negative adipose derived mesenchymal stem cells (CD73- AD-MSCs) of mouse

Project description:MSCs are a heterogeneous population and the specific population of MSCs may exhibit a selective ability for tissue repair. The aim of our research was to adapt the CD73+ subgroup of adipose derived MSCs (AD-MSCs) for the therapy of myocardial infarction (MI). Our results revealed that CD73+ AD-MSCs played more effective role in the acceleration function of cardiac recovery by promoting angiogenesis in a rat model of MI compared to mixed AD-MSCs and CD73- AD-MSCs. Microarray analysis shows differences between CD73+ and CD73- AD-MSCs when transcription profile of these two subgroups were compared, especially in VEGF pathway.

Retinoic acid signaling during priming licenses intestinal CD103+ CD8 TRM cell differentiation

Project description:CD8 tissue-resident memory T (TRM) cells provide front-line protection at barrier tissues; however, mechanisms regulating TRM cell development are not completely understood. Priming dictates the migration of effector T cells to the tissue, while factors in the tissue induce in situ TRM cell differentiation. Whether priming also regulates in situ TRM cell differentiation uncoupled from migration is unclear. Here, we demonstrate that T cell priming in the mesenteric lymph nodes (MLN) regulates CD103+ TRM cell differentiation in the intestine. In contrast, T cells primed in the spleen were impaired in the ability to differentiate into CD103+ TRM cells after entry into the intestine. MLN priming initiated a CD103+ TRM cell gene signature and licensed rapid CD103+ TRM cell differentiation in response to factors in the intestine. Licensing was regulated by retinoic acid signaling and primarily driven by factors other than CCR9 expression and CCR9-mediated gut homing. Thus, the MLN is specialized to promote intestinal CD103+ CD8 TRM cell development by licensing in situ differentiation.

CD73 knockdown effect in pancreatic cancer cell lines

Project description:Recent studies have shown that non-enzymatic function of CD73 play a key role in tumor progression, but this function of CD73 in pancreatic cancer cells has not been studied. In the present study, PANC-1 cell lines were transfected with CD73 siRNA, and proliferation ability and cell cycle was significantly inhibited. However, little is known about the mechanisms involved in CD73 regulation in tumors.

Effector TH17 cells give rise to long-lived TRM cells that are essential for an immediate response against bacterial infection

Project description:Mucosal barrier surfaces serve as the critical first line of defense separating our bodies from the plethora of pathogenic microorganisms that inhabit our environment. Adaptive immunity provides life-long protection through the generation of a central and effector memory T-cell pool, memory B cells and the recently described population of tissue resident memory cells (TRM). The cellular origin of TRM CD4 cells is unknown and the contribution of this CD4 memory population to host defense still remains elusive. By using IL-17A tracking-fate-mouse models we found that a significant fraction of the CD4 TRM cells derive from IL-17A producing effector (TH17) cells following primary immunization. Maintenance of these resting exTH17 TRM cells is mediated by IL-7, produced by lymphatic endothelial cells. During a memory response, we show that neither antibodies, nor gd T cells, nor circulatory memory T cells are sufficient for the rapid host defense required to eliminate the pathogen. Using parabiosis and depletion studies, we demonstrated that CD4 exTH17 TRM cells play an important role in respiratory defense and bacterial clearance. Upon infection, exTH17 TRM cells rapidly produce IL-17A and IFN-γ to promote neutrophil infiltration and bacterial clearance. These studies delineate the origin, function and importance of airway CD4 TRM cells during bacterial infection, offering novel strategies for targeted vaccine design, which is especially imperative for those pathogens that are resistant to antibiotic treatment.
