Telephone: +44(0) 20 7882 2352


Trained as a molecular biologist, at The Weizmann Institute of Science in Israel, his research activities have included the cloning of several interferons, interleukins and their receptors. He has contributed to the cloning and development of interferon beta as a therapeutic agent and the use of suicidal genes for cancer gene therapy.

Current research interests include the development of novel targeted therapeutics, gene transfer strategies for the treatment of rheumatoid arthritis and other autoimmune diseases via molecular design and cellular engineering including stem cells. He is member of the editorial board of Gene Therapy and Arthritis Research and Therapy and has served as Assistant Editor of Rheumatology. He became Centre Lead for Bone and Joint Research Unit at the William Harvey Research Institute in 1999.

Bone and Joint Research Unit

BJRU investigates the pathological and genetic mechanism of arthritic diseases, research the responsiveness to biological therapies to define biomarkers (work lead by Prof. Mageed) and develops gene transfer strategies for their treatment (with Dr. D. Gould) via cellular engineering, molecular design (using targeted antibodies, work lead by Dr. A. Nissim) and genetic engineering.

Regeneration of damaged tissues is pursued by engineering stem cells for targeting and survival in pathological conditions where absence of trophic factors limits regeneration.

A recent development has been the design of latent cytokines. By fusing the latency associated peptide (LAP) of TGFβ and a cytokine with therapeutic potential, via a metalloproteinase (MMP) cleavage site, renders the cytokine inactive until it reaches a site of inflammation where the high levels of MMP activity releases it. The LAP provides for a shell that inhibits the interaction of the cytokine with its receptors increasing its half- life and assures delivery to sites of disease. Proof of concept has been provided in many models of disease including: arthritis, multiple sclerosis, atherosclerosis, humanised model of graft vs. host disease and cancer. This platform delivery technology led to the establishment of Stealthyx Therapeutics Ltd. a spin-out company with patents granted worldwide.

Structure of a latent cytokine

The latent cytokine delivery system (Prothyx ® ) is a fusion protein between the latency associated peptide of TGF? that confers a shell structure by dimerisation and a peptide or cytokine with pharmacological properties linked via a metalloproteinase cleavage site. This delivery system provides longer half-life, disease-specific delivery and latency i.e. no side effects. Applications in: autoimmunity, inflammation, cancer, atherosclerosis, infection and regeneration.
