ABSTRACT:
Disclosed are compositions and methods of blocking T cell signal transduction by introducing into a T cell a peptide comprising a PI 3-kinase-binding-sequence which decreases the association of PI 3-kinase with CD28. Also disclosed are compositions and methods of amplifying T cell activation by introducing into a T cell, a plurality of modified T cell surface proteins, the cytoplasmic tail of which comprises a plurality of copies of a PI 3-kinase-binding-sequence.
