通过对抗IL-10驱动的MARCH 1介导的泛素化和MHC II类的降解,CD 83可以增强树突状细胞的免疫原性。有效的疫苗佐剂必须诱导树突状细胞(DC)上的主要组织相容性(MHC)II类蛋白和共刺激分子CD 86的表达。然而,一些佐剂引起细胞因子的产生,导致不利的炎症后果。开发选择性增加MHC II类和CD 86表达而不触发不需要的细胞因子产生的药物需要更好地理解影响DC中MHC II类和CD 86产生和降解的分子机制。在这里,我们研究如何CD 83,成熟的DC表面上表达的免疫球蛋白,促进MHC II类和CD 86的表达。使用具有N-乙基-N-亚硝基脲诱导的突变的小鼠消除CD 83的跨膜(TM)区域,我们发现CD 83的TM结构域通过阻断MHC II类与泛素连接酶MARCH 1的结合来增强MHC II类和CD 86的表达。CD 83的TM区阻断DC中IL 10驱动的MARCH 1依赖性泛素化和MHC II类和CD 86的降解。利用这一翻译后途径促进DC上的MHC II类和CD 86表达可能提供增强疫苗免疫原性的机会。
By opposing IL-10–driven, MARCH1-mediated ubiquitination and degradation of MHC class II, CD83 may boost the immunogenicity of dendritic cells. Effective vaccine adjuvants must induce expression of major histocompatability (MHC) class II proteins and the costimulatory molecule CD86 on dendritic cells (DCs). However, some adjuvants elicit production of cytokines resulting in adverse inflammatory consequences. Development of agents that selectively increase MHC class II and CD86 expression without triggering unwanted cytokine production requires a better understanding of the molecular mechanisms influencing the production and degradation of MHC class II and CD86 in DCs. Here, we investigate how CD83, an immunoglobulin protein expressed on the surface of mature DCs, promotes MHC class II and CD86 expression. Using mice with an N-ethyl-N-nitrosourea–induced mutation eliminating the transmembrane (TM) region of CD83, we found that the TM domain of CD83 enhances MHC class II and CD86 expression by blocking MHC class II association with the ubiquitin ligase MARCH1. The TM region of CD83 blocks interleukin 10–driven, MARCH1-dependent ubiquitination and degradation of MHC class II and CD86 in DCs. Exploiting this posttranslational pathway for boosting MHC class II and CD86 expression on DCs may provide an opportunity to enhance the immunogenicity of vaccines.
