DNA encoding antibody molecules which bind human IL-17
View Patent ↗The invention relates to antibody molecules having specificity for antigenic determinants of IL-17, therapeutic uses of the antibody molecules and methods of producing the antibody molecules.
1. An isolated DNA molecule encoding the heavy and/or light chain(s) of a neutralising antibody which binds human IL-17, wherein the antibody comprises a heavy chain, which variable domain comprises a CDR having the sequence given in SEQ ID NO: 1 for CDR-H1, a CDR having the sequence given in SEQ ID NO: 2 for CDR-H2 and a CDR having the sequence given in SEQ ID NO: 3 for CDR-H3; and a light chain, which variable domain comprises a CDR having the sequence given in SEQ ID NO: 4 for CDR-L1, a CDR having the sequence given in SEQ ID NO: 5 for CDR-L2 and a CDR having the sequence given in SEQ ID NO: 6 for CDR-L3.
2. A cloning or expression vector comprising the DNA molecule according to claim 1 .
3. The vector according to claim 2 , wherein the vector comprises the sequences given in SEQ ID NO: 14 and SEQ ID NO: 18.
4. An isolated host cell comprising the cloning or expression vector according to claim 3 .
5. A process for the production of a neutralising antibody, which binds human IL-17 and is encoded by the DNA molecules of SEQ ID NO:14 and 18, comprising culturing the host cell of claim 4 under conditions suitable for expression of the antibody, and isolating the antibody.
6. An isolated host cell comprising the cloning or expression vector according to claim 2 .
