Skin allograft rejection
WebbBenichou (56) showed that, during mouse skin allograft rejection, donor MHC molecules are processed and presented as peptides by the recipient's APC in vivo, eliciting CD4 + and CD8 + T cell responses which are restricted to the … Webb12 aug. 2008 · However, the role for the innate immune system in the skin allograft rejection promoted by indirectly primed CD4 + T cells has not been firmly established yet. It was reported that indirectly primed (cross-primed) CD8 + T cells can also promote skin allograft rejection by themselves (16, 17).

WebbT cells play a major role in the acute rejection of transplanted organs. Using mice transgenic for a T-cell-restricted NF-κB super-repressor (IκBα∆N-Tg mice), we have previously shown that T-cell-NF-κB is essential for the acute rejection of cardiac but not skin allografts. In this study, we investigated the mechanism by which skin grafts … WebbAllograft Skin: The Rigors of Transplant Eligibility ...

WebbThe transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and … WebbHere we show that rejection correlates with progressive migration of CD4(+) and CD8(+) T cells into the graft. In contrast, the day +7 CD3 Ab tolerogenic effect is associated with absence of de novo accumulation of CD8(+) T cells within the allograft while CD4(+) T-cell migration is not altered.

WebbThe source of the skin is autograft or allograft. But mostly, the donors are self (autograft). The donors are living source. The skin allografts will show the rejection phenomenon because of the extremely high density of the MHC class I molecule antigens. These allografts are supported by immunosuppressive therapy.
