Chimeric receptors with 4-1BB stimulatory signaling domain

摘要

The present invention relates to a chimeric receptor capable of signaling both a primary and a co-stimulatory pathway, thus allowing activation of the co-stimulatory pathway without binding to the natural ligand. The cytoplasmic domain of the receptor contains a portion of the 4-1BB signaling domain. Embodiments of the invention relate to polynucleotides that encode the receptor, vectors and host cells encoding a chimeric receptor, particularly including T cells and natural killer (NK) cells and methods of use.

主权项

1. A polynucleotide encoding a chimeric receptor comprising: (a) an extracellular ligand-binding domain comprising an anti-CD19 single chain variable fragment (scFv) domain; (b) a transmembrane domain of CD8α; and (c) a cytoplasmic domain comprising a human 4-1BB signaling domain and a CD3ζ signaling domain.
