A recent article published in Science translational Medicine by Spector et al. set out to determine the contribution of fundamental research to the generation of new medicines. By tracking the scientific origins of some of today’s most “transforming” FDA-approved drugs, including medicines such as TNF blockers, ACE inhibitors, kinase inhibitors and others, they find that approximately 80% of the 28 medicines studied, originated as basic research discoveries by scientist seeking to understand a biological process or disease. It is noteworthy, that the path to drug discovery that starts with basic scientific research more often than not includes fundamental research work performed in mouse models of disease that provide invaluable insights and proof of concept on in vivo disease mechanisms and drug activity. One such example of the invaluable contribution of animal disease models in the path to drug discovery, is the human TNF transgenic Tg197 arthritis mouse model that in 1991 provided the first in vivoevidence that deregulated TNF production was causal to chronic polyarthritis (Keffer et al.).


Tg54531 is a transgenic mouse with transmembrane human TNF deregulated expression resulting in the spontaneous development of arthritis pathology that closely resembles human rheumatoid arthritis.

The mice develop arthritis with 100% penetrance and provide a fast in-vivo model for evaluating human therapeutics targeting rheumatoid arthritis.

The Tg5453 mouse model was successfully used in establishing the therapeutic efficacy of Remicade®, the first anti-TNF therapeutic to be successfully applied in the clinic, and is currently used for screening anti-rheumatoid candidate drugs.
