Summary
Tumor necrosis factor (TNF) and type I interferons (IFNs) are key immune signals. This review explores how IFN-beta signaling regulates TNF-induced gene expression in myeloid cells during inflammation.
Area of Science:
- Immunology
- Molecular Biology
- Cell Biology
Background:
- Tumor necrosis factor (TNF) and type I interferons (IFNs) are crucial mediators of innate immune responses, often induced by microbial stimuli.
- These cytokines play significant roles in the pathogenesis of chronic inflammatory diseases, including rheumatoid arthritis and systemic lupus erythematosus.
- Activated macrophages are central to inflammatory reactions and are major producers of TNF in both innate immunity and chronic inflammation.
Purpose of the Study:
- To review the regulatory mechanisms governing the interaction between TNF and type I IFNs during inflammatory processes.
- To elucidate the role of an autocrine IFN-beta loop in modulating TNF-induced gene expression programs within myeloid cells.
Main Methods:
- Literature review focusing on molecular and cellular mechanisms of cytokine interaction.
- Analysis of gene expression data related to TNF and IFN signaling pathways in myeloid cells.
Main Results:
- Highlights the known roles of TNF and type I IFNs in immunity and inflammation.
- Identifies a knowledge gap regarding the interplay between these cytokines at inflammatory sites.
- Discusses the proposed mechanism of an IFN-beta-mediated autocrine loop regulating TNF responses.
Conclusions:
- The interaction between TNF and type I IFNs is critical for immune responses and inflammatory diseases.
- An IFN-beta autocrine loop represents a key regulatory mechanism for TNF-induced gene expression in myeloid cells.
- Further research into these interactions can inform therapeutic strategies for chronic inflammatory conditions.

01:24T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
02:26NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
01:16TGF - β Signaling Pathway
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
