Structural insights into the disruption of TNF-TNFR1 signalling by small molecules stabilising a distorted TNF

Abstract

Small molecules stabilising a distorted TNF trimer can inhibit TNF signaling, but the underlying mechanism is unclear. Here, the authors characterize the inhibitor-bound TNF-receptor complex structurally and biochemically, showing that the inhibitors alter TNF-receptor binding stoichiometry and cluster formation.
