Abstract

Official abstract text for this publication.

Fibronectin type III (FN3) domain antibodies, polynucleotides capable of encoding the FN3 domain antibodies or antigen-binding fragments, cells expressing FN3 domain antibodies or antigen-binding fragments, as well as associated vectors and detectably labeled FN3 domain antibodies or antigen-binding fragments may be used to engineer FN3 domain-targeting chimeric antigen receptors (CARs). Methods of making the FN3 domain antibodies, CARs, and engineered immune cells, and methods of using the engineered immune cells are applicable to treat diseases including cancer.

First claim

Opening claim text (preview).

We claim: 1. An isolated polynucleotide encoding a chimeric antigen receptor (CAR) comprising: (a) an extracellular domain comprising an scFv comprising the amino acid sequence of SEQ ID NOs: 72 or 73, wherein the extracellular domain specifically binds to a non-randomized region of an FN3 domain; (b) a transmembrane domain comprising the amino acid sequence of SEQ ID NO: 25; and (c) an intracellular signaling domain comprising a co-stimulatory domain comprising the amino acid sequence of SEQ ID NO: 26, and a primary signaling domain comprising the amino acid sequence of SEQ ID NO: 27, wherein the CAR optionally further comprises a hinge region comprising the amino acid sequence of SEQ ID NO: 24 connecting the extracellular domain and the transmembrane domain. 2. A vector comprising the polynucleotide of claim 1 . 3. A host cell comprising the vector of claim 2 . 4. A host cell comprising the polynucleotide of claim 1 .
