The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

13.9K
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...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

10.9K
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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.9K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Inflammatory Response01:28

Inflammatory Response

18.9K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

NF-κB-dependent Signaling Pathway

10.3K
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.

Summary
This summary is machine-generated.

Pro-inflammatory cytokines and bone morphogenetic proteins interact in rheumatoid arthritis. These cytokines stimulate bone morphogenetic protein production, which then modulates the cytokine effects on joint cells.

Area of Science:

  • Immunology
  • Developmental Biology
  • Rheumatology

Background:

  • Pro-inflammatory cytokines and bone morphogenetic proteins are typically studied in isolation.
  • Their distinct roles are traditionally confined to immunology and developmental biology, respectively.

Discussion:

  • Varas and colleagues demonstrate a novel cross-talk between pro-inflammatory cytokines and bone morphogenetic proteins within rheumatoid arthritis synoviocytes.
  • This interaction reveals a complex interplay previously uncharacterized in the context of inflammatory joint disease.

Key Insights:

  • Pro-inflammatory cytokines induce the production of bone morphogenetic proteins in rheumatoid arthritis synoviocytes.
  • Endogenously produced bone morphogenetic proteins subsequently modulate the impact of pro-inflammatory cytokines on these cells.

Outlook:

  • This finding opens new avenues for understanding rheumatoid arthritis pathogenesis.
  • Targeting this cytokine-BMP cross-talk may offer novel therapeutic strategies for rheumatoid arthritis.
