免疫环境是宿主对潜在自身抗原反应的重要决定因素。系统性红斑狼疮中靶向的自身抗原聚集在凋亡细胞的表面泡内,在离散的亚细胞包装内产生高浓度的自身抗原。我们在这里证明,当辛德毕斯病毒感染诱导细胞凋亡时,病毒抗原和自身抗原仅在凋亡细胞的小表面泡中共同聚集。这些水泡的表面富含病毒糖蛋白,可以看到病毒粒子从它们的表面起泡。我们认为,这些混合外来和自我起源的水泡定义了一种新的免疫环境,可能会挑战自我耐受。
Immune context is an essential determinant of the host response to potential autoantigens. The clustering of the autoantigens targeted in systemic lupus erythematosus within surface blebs of apoptotic cells generates high concentrations of autoantigen within discrete subcellular packages. We demonstrate here that when apoptosis is induced by Sindbis virus infection, viral antigens and autoantigens cocluster exclusively in small surface blebs of apoptotic cells. The surface of these blebs is rich in viral glycoproteins, and virions can be seen blebbing from their surface. We propose that these blebs of mixed foreign and self-origin define a novel immune context that may challenge self-tolerance.
