Background Anti-MHC Class I alloantibodies have been implicated in the processes of acute
and chronic rejection. These antibodies (Ab) bind to endothelial cells (EC) and transduce
signals leading to the activation of cell survival and proliferation pathways, including Src,
FAK and mTOR, as well as downstream targets ERK, S6 kinase (S6K) and S6 ribosomal
protein (S6RP). We tested the hypothesis that phosphorylation of S6K, S6RP and ERK in
capillary endothelium may serve as an adjunct diagnostic tool for antibody-mediated …
