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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Inflammatory Response

Inflammatory Response

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,...

Background:

Atopic dermatitis (AD) is a chronic skin condition involving barrier defects, immune issues, and genetic factors.
Key inflammatory pathways include Th2 polarization and microbial imbalances, leading to itch and lesions.

Purpose of the Study:

To review the synergistic role of the IL-31/IL-33 axis in atopic dermatitis pathogenesis.
To explore the therapeutic potential of targeting this axis.

Main Methods:

Literature review focusing on the IL-31/IL-33 signaling pathway in AD.
Analysis of clinical trial data for targeted therapies.

Main Results:

IL-33 (alarmin) and IL-31 (cytokine) form a synergistic axis exacerbating AD.
This axis promotes inflammation, impairs skin barrier, and induces pruritus via neuronal activation.
Elevated IL-31/IL-33 levels correlate with AD severity.

Conclusions:

Targeting the IL-31/IL-33 axis is a promising therapeutic strategy for AD.
Nemolizumab (anti-IL-31RA) shows efficacy in reducing AD symptoms and itch.
Anti-IL-33/ST2 therapies have variable results, indicating the need for further research and patient stratification.
