Article Title: Structures of clinical antibodies bound to IL-33 uncover two distinct epitopes underlying differential efficacy

doi: 10.1080/19420862.2026.2639673

Figure Lengend Snippet: SPR competition assays of three antibodies and ST2. IL-33 was immobilized on a CM5 sensor chip. Injections were performed in two steps: first, protein 1 was injected for 150 s, followed by a mixture of protein 1 and protein 2 for 150 s. From left to right: competition profiles for itepekimab + ST2, etokimab + ST2, and tozorakimab + ST2, ST2 = 200 nM，Abs = 100 nM.
