Migration of dendritic leukocytes from cardiac allografts into host spleens. A novel pathway for initiation of rejection.
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 …
