Tg3647 mice over-express human TNF that leads to the gradual development of spontaneous slow progressing chronic inflammatory polyarthritis with 100% penetrance.
Targeting TNF-α as a treatment modality has shown tremendous success, however there are several limitations associated with the current anti-TNF-α biologic drugs including: immunogenicity, life-threatening infections, resistance to treatment, complexity of manufacture and cost of treatment. Ubah et al. report the in vivo efficacy of novel anti-TNF-α formats generated from molecular engineering of variable new antigen receptors (VNARs), originally derived from the immune system of an immunized nurse shark.

Collagen antibody-induced arthritis (CAIA) is a simple mouse model of rheumatoid arthritis that can be used to address questions relating to the pathogenic mechanisms of the disease and serves as a platform for the evaluation of candidate therapeutic agents.
Biomedcode has standardized the model in
- C57BL/6 wild type mice,
- Mice humanized for hTNFR1
- Tg1278TNFKO human TNF transgenic mice
- Mice humanized for both TNF and TNFR1
and developed platforms to allow the evaluation of different arthritis therapeutics.
The evolution of preclinical testing through novel humanized precision disease models
Scientists of Biomedcode present in PLOS Computational Biology a new computational framework revealing key differences between four rheumatoid arthritis medications and their impact on biological pathways in mice.

TgA86 mice overexpress mouse transmembrane TNF from a Δ1-12 mTNF-globin transgene. They develop with 100% incidence peripheral and axial joint pathology accompanied by new bone formation features, all characteristic of human SpA pathology.
Biomedcode is pleased to announce that it has received funding from the European Regional Development Fund of the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE supporting the innovative research network HUPLA that combines the efforts of industrial and renowned academic partners to develop precision drug evaluation tools for the preclinical development of novel therapies for Multiple Sclerosis and Psoriasis.
