Insights

This chapter explores intracellular signaling pathways involved in rheumatoid arthritis (RA) pathogenesis, including key protein production and current therapeutic effects. It also discusses future therapeutic targets for RA.

Area of Science:

  • Molecular Biology
  • Immunology
  • Rheumatology

Background:

  • Extracellular signals regulate intracellular pathways, affecting protein synthesis.
  • Specific proteins like cytokines and matrix metalloproteinases contribute to rheumatoid arthritis (RA) pathogenesis.
  • Understanding these pathways is crucial for RA treatment.

Purpose of the Study:

  • To discuss key signal transduction pathways in RA.
  • To review the impact of current RA therapeutics on these pathways.
  • To identify potential future therapeutic targets for RA.

Main Methods:

  • Review of signal transduction pathways including TNF receptor, IL receptor, MAPK, CD14/TLR, and T cell signaling.
  • Analysis of existing RA therapeutics' effects on these pathways.
  • Exploration of novel therapeutic targets.

Main Results:

  • Detailed description of multiple signaling cascades involved in RA.
  • Assessment of how current RA drugs modulate these pathways.
  • Identification of specific molecular targets for future RA therapies.

Conclusions:

  • Signal transduction pathways are central to RA pathogenesis.
  • Current RA treatments partially target these pathways.
  • Future RA therapies may focus on novel molecular targets within these pathways.

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.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
The JAK-STAT Signaling Pathway01:20

The 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...
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...
T Cell Types and Functions01:24

T Cell Types and Functions

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...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
