长期以来,人们一直认为,宿主对全血管同种异体器官移植的敏感化发生在移植物本身的外围。在这篇报告中,我们展示了供者来源的MHC II类阳性(Ia+)DL从小鼠心脏移植迅速迁移到受者的脾中,在那里它们定位于外周白髓,并主要与CD4+T淋巴细胞相联系。这为针对完全血管化的同种异体移植物提供了一条新的中枢致敏途径,并且很可能代表了一种针对从外周组织移行的血源性DL上的抗原产生免疫反应的途径。
It has been a long-standing dogma that host sensitization against fully- vascularized organ allografts occurs peripherally within the graft itself. In this report we show that donor-derived MHC class II-positive (Ia+) DL migrate rapidly out of mouse cardiac allografts into the recipients' spleens where they home to the peripheral white pulp and associate predominantly with CD4+ T lymphocytes. This provides a novel route for central sensitization against fully vascularized allografts, and most likely represents a pathway by which immune responses are generated against antigens on blood-borne DL emigrating from peripheral tissues.
