Project description:FAN (Factor associated with neutral sphingomyelinase activation) is an adaptor protein that constitutively binds to TNF-R1. Microarray analysis was performed in fibroblasts derived from wild-type or FAN knockout mouse embryos to evaluate the role of FAN in TNF-induced gene expression. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process.

Project description:TNF is a key inflammatory cytokine that warns recipient cells of a nearby infection or tissue damage. Acute exposure to TNF activates characteristic oscillatory dynamics of the transcription factor NFκB and induces a characteristic gene expression program; these are distinct from the responses of cells directly exposed to pathogen-associated molecular patterns (PAMPs). Here we report that tonic TNF exposure is critical for safeguarding TNF’s specific functions. In the absence of tonic TNF conditioning, acute exposure to TNF causes 1) NFκB signaling dynamics that are less oscillatory and more like PAMP-responsive NFκB dynamics, 2) immune gene expression that is more similar to the Pam3CSK4-response program, 3) broader epigenomic reprogramming that is characteristic of PAMP-responsive changes. We show that tonic TNF signaling effects subtle changes to TNF receptor availability and dynamics such that enhanced pathway activity results in non-oscillatory NFκB. Our results reveal tonic TNF signaling as a key tissue determinant of the specific characteristics of cellular responses to acute paracrine TNF exposure, and their distinction from responses to direct exposure to PAMPs.

Project description:TNF plays a key role in inflammation and bone resorption. However, the mechanisms regulating TNF-mediated osteoclastogenesis remain largely unclear because its direct osteoclastogenic ability is weak. Here, we found that TGFβ priming enables TNF to effectively induce osteoclastogenesis from macrophages, independently of the osteoclastogenic action of RANKL. Lack of TGFβ signaling in macrophages suppresses inflammatory, but not physiological, osteoclastogenesis and bone resorption in vivo. Mechanistically, TGFβ priming reprograms macrophage response to TNF towards osteoclastogenesis by remodeling chromatin accessibility and histone modification. TGFβ and TNF induce an unconventional osteoclastogenic program, which includes the suppression of the TNF-induced IRF1-IFNβ-IFN stimulated gene (ISG) axis, promotion of IRF8 degradation and B-Myb induction. These mechanisms are present in RA, in which TGFβ level is elevated and correlated with osteoclast activity. Our findings identify a function and mechanism of action for TGFβ in TNF-mediated inflammatory osteoclastogenesis, and open avenues for selective treatment of inflammatory bone loss.
