Insights

Tumour necrosis factor (TNF) has dual roles in immunity and inflammation. Research explores how its receptors (TNF-R) and associated proteins trigger cellular signals, impacting various conditions.

Area of Science:

  • Immunology and Molecular Biology
  • Cellular Signaling Pathways

Background:

  • Tumour necrosis factor (TNF) is a cytokine with critical roles in anti-infection and anti-tumour immunity, as well as in systemic inflammatory response syndrome (SIRS).
  • Two distinct TNF receptors (TNF-R) mediate TNF's diverse biological effects.
  • The specific functions of TNF-R in various cell types and their downstream signaling mechanisms remain incompletely understood.

Purpose of the Study:

  • To elucidate the precise roles of TNF receptors (TNF-R) in mediating the effects of Tumour necrosis factor (TNF).
  • To investigate the molecular mechanisms by which TNF binding to its receptors initiates downstream cellular signaling.
  • To identify key TNF-R-associated proteins involved in signal transduction.

Main Methods:

  • Analysis of TNF-induced receptor oligomerization.
  • Investigation of downstream signaling pathways initiated by TNF receptor activation.
  • Identification and characterization of TNF receptor-associated proteins, including kinases.

Main Results:

  • Tumour necrosis factor (TNF) binding induces oligomerization of its receptors (TNF-R).
  • This oligomerization is a key event linking receptor activation to intracellular signaling cascades.
  • Emerging evidence points to the involvement of TNF-R-associated proteins, such as kinases, in initiating cytoplasmic signal transduction.

Conclusions:

  • TNF receptor oligomerization is crucial for initiating downstream signaling.
  • TNF-R-associated proteins, including kinases, play a significant role in mediating TNF's cellular effects.
  • Further research into these pathways will clarify TNF's dual roles in health and disease.

Enzyme-linked Receptors01:13

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
TGF - β Signaling Pathway01:16

TGF - 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...
Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
NF-κB-dependent Signaling Pathway02:26

NF-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.
