T Cell Types and Functions

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...

The JAK-STAT Signaling Pathway

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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Transducer Mechanism: Enzyme-Linked Receptors

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:

Summary

This summary is machine-generated.

Toll-like receptor 8 (TLR8) drives rheumatoid arthritis (RA) progression by promoting inflammation and joint damage. Inhibiting TLR8 offers a promising therapeutic strategy for treating RA patients.

Area of Science:

Immunology
Rheumatology

Background:

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint inflammation and destruction.
The precise molecular mechanisms underlying RA pathogenesis are not fully understood.

Purpose of the Study:

To investigate the role of Toll-like receptor 8 (TLR8) in RA pathogenesis.
To evaluate TLR8 as a potential therapeutic target for RA.

Main Methods:

Analysis of gene expression profiles in RA patients.
In vitro studies using RA-derived cells (FLS, HUVECs, PBMCs) and animal models (RA monkeys).
In vivo evaluation of a TLR8 inhibitor in collagen-induced arthritis (CIA) mouse and RA rabbit models.

Main Results:

TLR8 is overexpressed in RA patients and correlates with disease activity.
TLR8 activation promotes synovial hyperplasia, angiogenesis, and inflammation, driving RA progression.
TLR8 inhibition significantly reduced disease severity and joint damage in preclinical RA models.

Conclusions:

TLR8 plays a pathogenic role in rheumatoid arthritis.
Targeting TLR8 represents a novel therapeutic approach for RA.
