In parallel, STS attenuated inflammatory signalling by inhibiting NF-κB pathway activation, as reflected by reduced NF-κB protein levels, stabilisation of its inhibitory regulator IκBα as well as suppression of IL-6, TNF-α and TGF-β gene expression, followed by a trend towards reduced IFN-γ gene levels. STS further modulated macrophage polarisation by reducing M1-like macrophages, as shown by decreased F4/80<sup>+</sup>CD80<sup>+</sup> signal, while CD206 immunoreactivity increased.
