Abstract
Methods for developing disease-related nanobodies and related products and kits are provided. The disease-specific proteins are extracellular matrix (ECM) proteins, domains or epitopes that are associated with various aspects of disease and are not present, or are present in very low quantities, in non-diseased individuals. Highly effective nanobodies capable of specifically binding to these ECM protein epitopes useful in in vivo imaging assays, the detection, diagnosis and treatment of diseases as well as monitoring therapeutic progress in a patient with a disease are provided herein.
Claims9
A chimeric antigen receptor (CAR) construct comprising an ectodomain comprising a nanobody which is specific for and binds directly to a diseased state extracellular matrix (ECM) epitope, wherein the diseased state ECM epitope is present in greater amounts in a diseased tissue than in a normal tissue, a transmembrane domain, and an endodomain, wherein the nanobody comprises a complementarity determining region (CDR) 1, CDR2 and CDR3 comprising a) SEQ ID NO:
- 19, SEQ ID NO:
- 36, and SEQ ID NO:
- 53, respectively;
- b) SEQ ID NO:
- 25, SEQ ID NO:
- 42, and SEQ ID NO:
- 59, respectively;
- c) SEQ ID NO:
- 26, SEQ ID NO:
- 43, and SEQ ID NO:
- 60, respectively;
- or d) SEQ ID NO:
- 28, SEQ ID NO:
- 45, and SEQ ID NO:
- 62, respectively.
A chimeric antigen receptor (CAR) construct comprising an ectodomain comprising a sequence set forth in SEQ ID NOs:
- 1-4 or an antigen binding fragment thereof which is specific for and binds directly to a diseased state extracellular matrix (ECM) epitope, wherein the diseased state ECM epitope is present in greater amounts in a diseased tissue than in a normal tissue, a transmembrane domain, and an endodomain.
