Potent T cell agonism mediated by a very rapid TCR/pMHC interaction.

abstract：:The transferrin receptor (TfR) was recently proposed as putative natural killer (NK) cell target structure. Here data are presented against this hypothesis and it is shown that low TfR expression and high NK sensitivity can occur concommitantly .
