I wish to point out that I no longer stand by the views reported in my News and Views article “Immunology: Ways around rejection” (Nature 377, 576–577; 1995), which dealt with a paper in the same issue (“A role for CD95 ligand in preventing graft rejection” by D. Bellgrau et al. — Nature 377, 630–635; 1995). My colleagues and I have been unable to reproduce some of the results of Bellgrau et al., as reported by J. Allison et al. (Proc. Natl Acad. Sci. USA 94, 3943-3947; 1997).

D. Bellgrau et al. (e-mail: don.bellgrau@uchsc.edu)considerthattheirresultsarereproducibleandstandbythem.Theynote,however,thatthemagnificationinFigure1g of their paper should be 113 times, not 45 times as printed. Both groups believe that other published data support their views, and interested readers can contact them directly for further details. — Editor, Nature.
