The invention involves dimeric forms of the protein known as fibroblast activation protein alpha, or 'FAP&#x3b1;' and its uses.

Isolated proteins containing portions of FAP&#x3b1; and other proteins

The invention relates to a prodrug that is capable of being converted into a drug by the catalytic action of human fibroblast activation protein (FAP&agr;), said prodrug having a cleavage site which is recognised by FAP&agr;, and said drug being cytotoxic or cytostatic under physiological conditions.

FAP-activated anti-tumour compounds

Recombinant antibody proteins are provided that specifically bind fibroblast activation protein alpha (FAP&agr;) and comprise framework modifications resulting in the improved producibility in host cells. The invention also relates to the use of said antibodies for diagnostic and therapeutic purposes and methods of producing said antibodies.

FAP&agr;-specific antibody with improved producibility

The invention provides for the production of several humanized murine antibodies specific for the antigen FB5, which is recognized by the murine antibody FB5. The FB5 antigen is expressed on the luminal surface of vascular endothelial cells of a wide range of malignant tumours. The invention also provides for numerous polynucleotide encoding humanized FB5 specific antibodies, expression vectors for producing humanized FB5 specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized FB5 specific antibodies. Additionally, the invention provides methods of treating cancer using FB5 specific antibodies.

Method for treating cancers which present antigen FB5 with humanized antibodies

The invention provides for the production of several humanized murine antibodies specific for the antigen LK26, which is recognized by the murine antibody LK26. This antigen is expressed on all choriocarcinoma, teratocarcinoma and renal cancer cell lines whereas it is not expressed on cell lines of leukaemias, lymphomas, neuroectodermally-derived and epithelial tumor cell lines (excepting a small subset of epithelial cell lines). Furthermore, whereas renal cancer cell lines express the LK26 antigen, normal renal epithelial cells do not. Similarly, with the exception of the trophoblast, all normal adult and fetal tissues tested are negative for the LK26 phenotype. The invention also provides for numerous polynucleotide encoding humanized LK26 specific antibodies, expression vectors for producing humanized LK26 specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized LK26 specific antibodies. Additionally, the invention provides methods of treating cancer using LK26 specific antibodies.
