Infiltrate and deposition of Ig in the graft / 中华器官移植杂志

ABSTRACT

We investigated the mechanism of tolerance induction by identifying differences in infiltrating cell population and Ig subclasses deposition between tolerant and rejecting rat liver allografts.There were occasional minor differences in the T cell or CD11 b/c+(monoeyte/macrophage/granulocyte)infiltrate.By contrast,there was a major difference in B cell infiltrate with more B cells in tolerant grafts.IgM was increased in both tolerant and rejecting livers while deposition of IgG1 was observed in rejecting but not in tolerant livers.
