NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.4K
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.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

10.1K
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...

Regulation of the Unfolded Protein Response

2.2K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

T Cell Types and Functions01:24

T Cell Types and Functions

3.2K
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...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

7.1K
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...

  • Genetics
  • Molecular Biology

Background:

  • Type I interferon (IFN) gene transcription is regulated by Interferon Regulatory Factors (IRFs).
  • IRF5, alongside IRF3 and IRF7, is involved in type I IFN production.
  • IRF5 gene polymorphisms are associated with Systemic Lupus Erythematosus (SLE) susceptibility, indicating potential risk or protective roles.

Purpose of the Study:

  • To comprehensively review the role of IRF5 in immune-mediated responses.
  • To discuss the multifaceted role of IRF5 in conferring SLE susceptibility.

Main Methods:

  • Literature review of studies on IRF5 function and SLE pathogenesis.
  • Analysis of genetic data regarding IRF5 polymorphisms and SLE risk.
  • Examination of IRF5's involvement in various signaling pathways beyond type I IFN production.

Main Results:

  • IRF5 is implicated in type I IFN production and immune regulation.
  • IRF5 polymorphisms are linked to SLE susceptibility.
  • IRF5 influences other pathways, including B cell IgG switching, macrophage polarization, and apoptosis.

Conclusions:

  • IRF5's role in SLE pathogenesis may extend beyond dysregulated IFN expression.
  • IRF5 is a significant factor in immune responses and SLE susceptibility.
  • Further research into IRF5's diverse functions is warranted for understanding SLE.
