WebWe present evidence of a role for the TRIFosome downstream of TNF-R1, independent of TLR3 or TLR4 engagement. Specifically, TNF-induced cell death and inflammation in murine macrophages were driven by the TLR4 adaptor TRIF and the LPS co-receptor CD14, highlighting an important role for these proteins beyond TLR-mediated immune responses. WebOverall, LPS-induced CXCL10, CCL2, TNF-α, and NF-κB were most effectively downregulated by β-FNA; and β-FNA effects differed across brain regions, peripheral tissues, timing of the dose, and in some instances, in a sex-dependent manner. β-FNA reduced LPS-induced anxiety-like behavior most effectively in female mice.
