Transcriptome data of wt, Rbx1- or Ube2m- deficient Treg cells from mice

Project description:Cullin-RING Ligases (CRLs), upon activation by neddylation, play the key roles in regulating many biological processes. However, how CRL-neddylation regulates the function of Treg cells remains elusive. Here we show that mice with Treg-specific deletion of Rbx1, a RING component of CRLs required for its activity, developed an early-onset fetal inflammatory disorders and death at day ~25 after birth with disrupted homeostasis and impaired suppressive functions of Treg cells. Specifically, Rbx1 is essential for maintenance of the effector subpopulations in Treg cells, and regulates several inflammatory pathways. Similar phenotypes were seen in mice with deletion of Ube2m, a neddylation E2, in Treg cells, but with much lesser severity. Interestingly, Treg-specific deletion of Rbx2/Sag or Ube2f, the family member of Rbx1 or Ube2m, respectively, had no obvious phenotype. Thus, the Ube2m-Rbx1 axis is required for the maintenance of homeostasis and functions of Treg cells; and Rbx1 has Ube2m-independent roles in the fitness of Treg cells, suggesting a layer of complexity in neddylation activation of CRLs. We use the tranpritome dara to show the mechanism of the function of Rbx1 and Ube2m in Treg cells, also research the relationship of Rbx1 and Ube2m in Treg cells.

Transcriptome data of Foxp3-Cre, Rbx1&Sag-deficient Treg cells from mice

Project description:Neddylation is necessary for activation of Cullin-RING Ligases (CRLs) which degrade various immune regulatory proteins. Our recent study showed that while depletion of neddylation E2-E3 pair Ube2f-Sag in regulatory T cells (Treg cells) had no obvious phenotype, the same depletion of either Ube2m or Rbx1 caused inflammation disorders with different severity. Whether these E2s or E3s compensate each other in functional regulations of Treg cells is, however, previously unknown. In this report, we generated Foxp3Cre;Ube2mfl/fl;Ube2ffl/fl or Foxp3Cre;Rbx1fl/fl;Sagfl/fl double null mice by simultaneously deletion of both neddylation E2s or E3s in Treg cells, respectively. Remarkably, Ube2m&Ube2f double null mice developed much severe autoimmune phenotypes than Ube2m-null mice, indicating Ube2m significantly compensates Ube2f in Treg cells. The minor worsen autoimmune phenotypes seen at very early stage in Rbx1&Sag double null than Rbx1-null mice, is likely due to already severe phenotypes of the later, indicating a minor compensation of Rbx1 for Sag. The RNA profiling-based analyses revealed that up- and down-regulations of few signaling pathways in Treg cells are associated with the severity of autoimmune phenotypes. Finally, severer inflammation phenotypes seen in mice with double E3-null than with double E2-null Treg cells indicate a neddylation-independent mechanism of two E3s, also known to serve as the RING component of CRLs in regulation of Treg cell fitness.
