RACK1 targets MAVS to inhibit type I IFN signaling pathway. (A) Immunoblot analysis of MAVS, p-TBK1(S172), TBK1, p-IRF3(S386), and IRF3 in negative control and RACK1-overexpressing BHK-21 cell lines infected with BEFV of 0.1MOI for 24 h. Anti-β-actin was used as an internal reference control. (B) HEK-293 T cells were co-transfected with Luc-IFN-β and pRL-TK plasmids plus the indicated expression plasmids together with control or RACK1 plasmids. At 24 h post-transfection, the luciferase activities were measured with the dual-luciferase assay. (C) Immunoblot analysis of MAVS in negative-control and RACK1-overexpressing MDBK cell lines infected with BEFV of 0.1MOI for 24 h. The mean and standard deviation values were determined from three independent experiments; *, P ≤ 0.05.
IHC
Phospho-TBK1 (Ser172) Antibody at 1/200 staining Human tonsil tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 1.5 hours at 22°C. An HRP conjugated goat anti-rabbit antibody was used as the secondary antibody.
