The role of IL-23 and the IL-23/TH17 immune axis in the pathogenesis and treatment of psoriasis

Psoriasis is a chronic, immune-mediated disease affecting more than 100 million people worldwide and up to 2.2% of the population. The aetiology of psoriasis is thought to originate from an interplay of genetic, environmental, infectious and lifestyle factors. The manner in which genetic and environmental factors interact to contribute to the molecular disease mechanisms has remained elusive. However, the interleukin 23 (-23)/T-helper 17 (17) immune axis has been identified as a major immune pathway in psoriasis disease pathogenesis. Central to this pathway is the cytokine -23, a heterodimer composed of a p40 subunit also found in -12 and a p19 subunit exclusive to -23. -23 is important for maintaining 17 responses, and levels of -23 are elevated in psoriatic skin compared with non-lesional skin. A number of agents that specifically inhibit -23p19 are currently in development for the treatment of moderate-to-severe plaque psoriasis, with recent clinical trials demonstrating efficacy with a good safety and tolerability profile. These data support the role of this cytokine in the pathogenesis of psoriasis. A better understanding of the -23/17 immune axis is vital and will promote the development of additional targets for psoriasis and other inflammatory diseases that share similar genetic aetiology and pathogenetic pathways
