  • PubMed Abstract: 

    Interleukin (IL)-23 is a pro-inflammatory cytokine playing a key role in the pathogenesis of several autoimmune and inflammatory diseases. We have determined the crystal structures of the heterodimeric p19-p40 IL-23 and its complex with the Fab (antigen-binding fragment) of a neutralizing antibody at 2.9 and 1.9 A, respectively. The IL-23 structure closely resembles that of IL-12. They share the common p40 subunit, and IL-23 p19 overlaps well with IL-12 p35. Along the hydrophilic heterodimeric interface, fewer charged residues are involved for IL-23 compared with IL-12. The binding site of the Fab is located exclusively on the p19 subunit, and comparison with published cytokine-receptor structures suggests that it overlaps with the IL-23 receptor binding site.
