A new, stable trimeric TNFα structure is disclosed with distorted symmetry which can bind to the TNFR1 receptor to attenuate signalling therefrom, which can be used in the treatment and/or prevention of diseases associated with the soluble TNFα/TNFR1 interaction. Membrane-bound TNFα is not affected in its ability to signal through TNFR2, and thus the new structure of TNFα may be used in therapies which do not significantly raise the risk of infection or malignancy.
本研究公开了一种新的、稳定的三聚 TNFα 结构,这种结构具有扭曲对称性,可与 TNFR1 受体结合以减弱其信号传导,可用于治疗和/或预防与可溶性 TNFα/TNFR1 相互作用有关的疾病。膜结合型 TNFα 通过 TNFR2 发出信号的能力不受影响,因此,TNFα 的新结构可用于治疗不会显著增加感染或恶性肿瘤风险的疾病。
