Summary
Tumor necrosis factor (TNF) is crucial for apoptosis, inflammation, and immunity. Understanding its receptor-1 (TNF-R1) signaling pathways is key to treating diseases like cancer and arthritis.
Area of Science:
- Cellular Biology
- Immunology
- Molecular Biology
Background:
- Tumor necrosis factor (TNF) plays a central role in apoptosis, inflammation, and immunity.
- TNF is implicated in the pathogenesis of numerous human diseases, including sepsis, diabetes, cancer, osteoporosis, multiple sclerosis, rheumatoid arthritis, and inflammatory bowel diseases.
- The interaction between TNF and its receptor, TNF-R1, initiates critical signal transduction pathways.
Purpose of the Study:
- To provide an overview of the current understanding of TNF signaling pathways.
- To introduce a visual representation of TNF signaling through an STKE Connections Map.
Main Methods:
- Literature review of TNF signaling mechanisms.
- Elucidation of components and mechanisms involved in TNF-induced signal transduction.
- Development of a graphical representation (STKE Connections Map) of canonical TNF signaling.
Main Results:
- TNF-R1 activation leads to the formation of multiprotein signaling complexes at the cell membrane.
- Key components and mechanisms of TNF signaling pathways have been identified.
- A canonical view of TNF signaling is presented via the STKE Connections Map.
Conclusions:
- TNF signaling is a complex process involving multiple pathways initiated by TNF-R1 interaction.
- Detailed knowledge of TNF signaling is essential for understanding and treating a wide range of diseases.
- The STKE Connections Map offers a valuable tool for visualizing and comprehending TNF signaling.

01:24Intracellular Signaling Cascades
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
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.

01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
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...
