TNFR2-mediated signaling and TNFR2 function in immune cells.
| TNFR2 function | Signaling via TNFR2 | Ref. | |
|---|---|---|---|
| Effector T-cells | Co-stimulation and cell death induction | Elicit activation-induced cell death; upregulates the expression of the inhibitory receptor Tim3 | (42) |
| Regulatory T-cells | Proliferation, suppressive activity, stability | Enhance cell proliferation and stability through signaling pathways such as IKK/NF-κB, mTOR, and MAPK | (19, 56, 78) |
| MDSCs | Cell survival, suppressive activity, recruitment | Upregulation of cellular FLICE-inhibitory protein (c-FLIP) and inhibition of caspase-8 activity | (79) |
| Regulatory B-cells | Suppressive activity | Characterizes TLR9-driven formation of IL-10-producing B cells | (80) |
| Macrophages | Production of pro-inflammatory factors | Enhance activation of the p38 MAPK and NF-κB pathways | (25) |
| NK cells | Suppressive activity | Activating the BIRC3/TRAF1 signaling pathway | (24) |
| MSCs | Proliferation, functional properties, immunosuppressive activity | Promotes the expression of immunosuppressive proteins on MSCs | (81, 82) |
| EPCs | Survival, differentiation, and immunosuppressive activity | Increases the expression of pro-angiogenic mediators such as VEGF, basic fibroblast growth factor, and IL-8; production of different anti-inflammatory cytokines like IL-10, TGFβ, and HLA-G. | (83) |
