Project description:Tumor Necrosis Factor Alpha is a known pro-inflammatory cytokine that plays a key role in the pathogenesis of rheumatoid arthritis. Anti-cytokine therapies targeting Tumor Necrosis Factor Alpha have greatly succeeded in treating rheumatoid arthritis in many patients. Despite these developments, many of the mechanisms of Tumor Necrosis Factor Alpha action have yet to be uncovered. In this study, we incubated PBMCs from healthy donors and rheumatoid arthritis patients with Tumor Necrosis Factor Alpha and then performed their single-cell multi-omics analysis via BD Rhapsody. We have observed that Classical Monocytes have responded to the Tumor Necrosis Factor Alpha stimulation the most and that there was an activational threshold for such response that was dependent on the TNFR2 protein expression level. The profiling of TNFR2 protein expression level on immune cell populations can be a good predictive factor for the assessment of their activation by Tumor Necrosis Factor Alpha.

Project description:Hayashi2013 - Extended TNF-induced Signaling with Gene Expression Dynamics (Model B)
Tumor necrosis factor (TNF) plays a crucial role in inflammation and is associated with diseases such as rheumatoid arthritis and cancer. While TNF signaling pathways are well studied, targeted regulation of proinflammatory responses remains a challenge. In this study, Hayashi et al., (2013) developed a computational model to simulate TNF-induced activation of MAP kinase (p38), NF-κB, and proinflammatory gene expression in murine fibroblast cells. The model parameters were optimized to fit experimental data, ensuring accurate representation of TNF signaling dynamics. The simulations using in silico knockouts identified receptor-interacting protein 1 (RIP1) as a key regulator of TNF-driven proinflammatory responses. Experimental validation using Necrostatin-1, a RIP1 inhibitor, confirmed these predictions and demonstrated its potential as a therapeutic target for regulating proinflammatory mediators in TNF-driven diseases.
This model is described in the article:

Abstract:
Background: Tumor necrosis factor (TNF) is a widely studied cytokine (ligand) that induces proinflammatory signaling and regulates myriad cellular processes. In major illnesses, such as rheumatoid arthritis and certain cancers, the expression of TNF is elevated. Despite much progress in the field, the targeted regulation of TNF response for therapeutic benefits remains suboptimal. Here, to effectively regulate the proinflammatory response induced by TNF, a systems biology approach was adopted.
Results: We developed a computational model to investigate the temporal activations of MAP kinase (p38), nuclear factor (NF)-κB, and the kinetics of 3 groups of genes, defined by early, intermediate and late phases, in murine embryonic fibroblast (MEF) and 3T3 cells. To identify a crucial target that suppresses, and not abolishes, proinflammatory genes, the model was tested in several in silico knock out (KO) conditions. Among the candidate molecules tested, in silico RIP1 KO effectively regulated all groups of proinflammatory genes (early, middle and late). To validate this result, we experimentally inhibited TNF signaling in MEF and 3T3 cells with RIP1 inhibitor, Necrostatin-1 (Nec-1), and investigated 10 genes (Il6, Nfkbia, Jun, Tnfaip3, Ccl7, Vcam1, Cxcl10, Mmp3, Mmp13, Enpp2) belonging to the 3 major groups of upregulated genes. As predicted by the model, all measured genes were significantly impaired.
Conclusions: Our results demonstrate that Nec-1 modulates TNF-induced proinflammatory response, and may potentially be used as a therapeutic target for inflammatory diseases such as rheumatoid arthritis and osteoarthritis.

Project description:Autoreactive CD8+ T effector (eff) cells specific to vimentin, actin cytoplasmic 1, or non-muscle myosin heavy chain 9 epitopes, evade regulatory T (Treg) cells in patients with rheumatoid arthritis undergoing worsening disease and who would become non-responders to tumor necrosis factor (TNF)-α inhibitor therapy, in contrast to autoreactive CD8+ T naïve (N) cells that are efficiently controlled by Treg cells in healthy individuals or patients who would become responders. Gene expression analysis revealed that the autoreactive CD8+ TN cell subset is comprised of a heterogeneous population of cells at various stages of development in healthy individuals or patients. Mechanistically, the production of TNF-α by CD8+ TN cells and the killing activity by CD8+ Teff cells in response to the relevant self-antigens influence the endorsement or suppression of Treg function, respectively. These data provide evidence of a previously undescribed role of such mechanisms in the progression and therapy of a prototypical human autoimmune disease, such as rheumatoid arthritis.

Project description:Tumor necrosis factor receptor 2 (TNFR2), a membrane-bound tumor necrosis factor receptor expressed by regulatory T cells (Tregs), participates in Treg proliferation. Although a specific TNFR2 pathway has been reported, the signaling mechanism has not been completely elucidated. This study sought to clarify TNFR2 signaling in human Tregs using amplicon sequencing and single-cell RNA-sequencing to assess Tregs treated with a TNFR2 agonist antibody. Pathway enrichment analysis based on differentially expressed genes highlighted tumor necrosis factor α signaling via nuclear factor-kappa B, interleukin-2 signal transducer and activator of transcription 5 signaling, interferon-γ response, and cell proliferation-related pathways in Tregs after TNFR2 activation. TNFR2-high Treg-focused analysis found that these pathways were fully activated in cancer Tregs, showing high TNFR2 expression. Collectively, these findings suggest that TNFR2 orchestrates multiple pathways in cancer Tregs, which could help cancer cells escape immune surveillance, making TNFR2 signaling a potential anticancer therapy target.
