Summary
Interleukin-33 (IL-33), an inflammation-induced factor, acts both inside and outside cells. This review explores IL-33/ST2 signaling in skin inflammation and homeostasis.
Area of Science:
- Immunology
- Dermatology
- Molecular Biology
Background:
- Interleukin-33 (IL-33) is an unconventional member of the IL-1 family.
- IL-33 functions as both an intracellular gene regulator and an extracellular mediator.
- It signals through the ST2 receptor, a heterodimeric membrane-bound receptor.
Purpose of the Study:
- To review the complex biology of IL-33.
- To summarize the function of IL-33/ST2 signaling in skin.
- To discuss the clinical relevance of IL-33 in inflammatory skin conditions.
Main Methods:
- Literature review of existing studies on IL-33 and ST2.
- Analysis of IL-33/ST2 signaling pathways in immune responses.
- Examination of IL-33's role in tissue homeostasis and inflammatory skin diseases.
Main Results:
- IL-33 plays a critical role in immune responses within the skin.
- Dysregulation of IL-33/ST2 signaling is implicated in various inflammatory skin conditions.
- IL-33 contributes to maintaining skin tissue homeostasis.
Conclusions:
- IL-33 is a key player in skin immunity and inflammation.
- Understanding IL-33/ST2 signaling offers therapeutic potential for skin diseases.
- Further research is needed to fully elucidate IL-33's complex functions in dermatology.

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.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

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,...
