cIAP1/2 antagonization by SMAC mimetic induces non-canonical NF-κB mediated TH 17 cell homotypic interactions and increases their resistance to shear stress

Eur J Immunol. 2021 Aug;51(8):2097-2099. doi: 10.1002/eji.202048983. Epub 2021 May 27.

Abstract

SMAC antagonization of cIAP1/2 in TH 17 cells upregulates cell adhesion and cytoskeleton genes through the NIK-RelB and p52 axis. SMAC also increases the homotypic interactions of TH 17 cells through a non-canonical NF-κB- and integrin-mediated mechanism resulting in increased ability of TH 17 cells to withstand shear stress.

Keywords: NF-κB; SMAC; TH17; cIAP1/2; shear stress.
