IL4-IL10 Synerkine for treating OA

The present invention is in the field of immunology and pharmacology, particularly for treatment of osteoarthritis, chronic pain, inflammatory diseases or disorders, and related diseases and disorders. The invention particularly relates to a novel fusion protein comprising interleukin 4 (IL-4) and interleukin 10 (IL-10), optionally physically fused together by a linker. Particularly, the present invention provides an IL4-IL10 fusion protein endowed with a superior biological activity over a combination of the individual cytokines. The present invention also provides nucleic acid sequences encoding a IL4-IL10 fusion protein, expression vectors comprising such nucleic acid sequences, host cells or host organisms altered to harbour the nucleic acid sequence encoding the IL4-IL10 fusion protein and the IL4-IL10 fusion protein itself. The invention further provides methods for producing an IL4- IL10 fusion protein using a cell or organism harbouring such nucleic acid sequences.

Transgenic organisms comprising the nucleic acid sequence of the invention are also provided. The present invention also relates to pharmaceutical compositions comprising the IL4-IL10 fusion protein. Finally, the use of the IL4-IL10 fusion protein as a medicament, in particular for the prevention and/or treatment of osteoarthritis and of conditions characterized by local or systemic inflammation, immune activation, lymphoproliferation and/or chronic pain is taught herein.
