Open Access Abstract Introduction Despite the advent of biological therapies for the treatment of rheumatoid arthritis there is a compelling need to develop alternative therapeutic targets for nonresponders to existing treatments. Soluble receptors occur naturally in vivo such as the splice variant of the cell surface receptor for vascular endothelial growth factor VEGF - a key regulator of angiogenesis in rheumatoid arthritis. Bioinformatics analyses predict that the majority of human genes undergo alternative splicing generating proteins - many of which may have regulatory functions. The objective of the present study was to identify alternative splice variants ASV from cell surface receptor genes and to determine whether the novel proteins encoded exert therapeutic activity in an in vivo model of arthritis.
