Effect of bimekizumab in psoriatic arthritis: a new approach
Psoriatic arthritis is a complex, immune-mediated inflammatory disease affecting peripheral and axial joints, entheses, skin, and nails. The IL-17 cytokine family, which includes several dimeric isoforms with overlapping and distinct functions, has been implicated in the pathogenesis of psoriatic arthritis. In particular, IL-17A and IL-17F, which share 50% homology and exhibit overlapping proinflammatory activity, can form both homodimers and heterodimers.
