Overall, the autograft strategy followed by
allograft resulted in relapse - free survival rates of 20 - 25 % in the long term.
Indeed, our results indicate that adoptive transfer of CD8 + T cells from CD4 KO mice that had rejected corneal
allografts resulted in the rejection of 95 % of the corneal allografts transplanted to athymic recipients.

Using an approach developed at Maisonneuve - Rosemont, consisting of an autograft to reduce tumour mass followed by a family
allograft three to four months later to clean the bone marrow of myeloma cells with immune cells from a family donor (immunotherapy), the study
resulted in a total cure rate of 41 %, a record level using this strategy.
«Our study
results highlight that in a young athletic population,
allografts (tissue harvested from a donor) fail more frequently than using autografts (tissue harvested from the patient),» said Craig R. Bottoni, MD, lead author from Tripler Army Medical Center in Honolulu, Hawaii.
The
results of a typical experiment are shown in Figure 3 and demonstrate that even though spleen cells from CD4 KO mice could adoptively transfer corneal
allograft rejection, they did not display conventional CTL activity against either BALB / c corneal epithelial or endothelial cells.
The
results indicated that 54 % (38/70) of the BALB / c corneal
allografts underwent rejection in the CD4 KO hosts, while 100 % of the grafts were rejected in wild - type C57BL / 6 mice (Figure 1).
By contrast, adoptive transfer of CD8 − spleens cells from similar donors
resulted in the rejection of corneal
allografts in almost half of the hosts.
The
results reported here reaffirm previous findings indicating that T cells are absolutely required for corneal
allograft rejection in the mouse (3).
