Abstract: | Deubiquitination of NF-κB members by CYLD is crucial in controlling the magnitude and nature of cell activation. The naturally occurring CYLD splice variant, devoid of exons 7 and 8, lacks TRAF2 and NEMO binding sites. The role of this splice variant in dendritic cell (DC) function was analyzed using CYLDex7/8 mice, which lack the full-length CYLD (FL-CYLD) transcript and over-express the short splice variant (sCYLD). Bone marrow derived DCs (BMDC) from CYLDex7/8 mice display a hyper-reactive phenotype in vitro and in vivo and have a defect in establishing tolerance using DEC205-mediated antigen targeting to resting DCs. This phenotype was accompanied by an increased nuclear translocation of the IκB molecule Bcl-3, and increased degradation of cytoplasmic p105 in CYLDex7/8 BMDCs after stimulation. This suggests that in contrast to FL-CYLD, sCYLD is a positive regulator of NF-κB activity and its over-expression induces a hyper-reactive phenotype in DCs. |
