The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

9.5K
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...

NF-κB-dependent Signaling Pathway

7.9K
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.

Inflammatory Response

11.2K
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,...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

T Cell Types and Functions01:24

T Cell Types and Functions

1.5K
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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Area of Science:

  • Immunology
  • Developmental Biology
  • Regenerative Medicine

Background:

  • Tissue injury triggers immune responses crucial for repair and homeostasis.
  • The Wnt pathway is vital for cell proliferation and differentiation during tissue regeneration.
  • Wnt ligands modulate immune responses, but antagonists' roles in inflammation are unclear.

Purpose of the Study:

  • To review Dickkopf (DKK) family proteins as immunomodulators.
  • To elucidate the role of DKK proteins in tissue repair and chronic inflammation.
  • To highlight DKK proteins as potential therapeutic targets for immune diseases.

Main Methods:

  • Literature review of Wnt pathway components and DKK family proteins.
  • Analysis of DKK1, DKK2, and DKK3 functions in immune modulation.
  • Synthesis of current knowledge on DKK proteins in cancer and inflammatory diseases.

Main Results:

  • DKK family proteins (DKK1, 2, 3) exhibit significant immunomodulatory functions.
  • These proteins play critical roles in modulating immune responses during chronic inflammation.
  • DKK proteins are implicated in both cancer biology and other chronic inflammatory conditions.

Conclusions:

  • DKK family proteins represent a new class of immunomodulators.
  • Their functions in chronic inflammatory disorders offer insights into immune disease mechanisms.
  • DKK proteins are attractive molecular targets for therapeutic interventions in immune diseases.
