Summary
Psoriasis pathogenesis involves the interleukin (IL)-23/IL-17 axis. Dendritic cells (DC) are key players, making them a target for treating this chronic inflammatory skin disease.
Area of Science:
- Immunology
- Dermatology
- Cell Biology
Background:
- Psoriasis is a chronic inflammatory skin condition.
- Recent research highlights the critical role of the interleukin (IL)-23/IL-17 signaling pathway in psoriasis pathogenesis.
- Targeting IL-23 and IL-17 has shown therapeutic benefits for patients.
Purpose of the Study:
- To review the established role of dendritic cells (DC) in the development and progression of psoriasis.
- To explore DC subsets as potential therapeutic targets for psoriasis and related diseases.
Main Methods:
- Literature review focusing on immunological mechanisms in psoriasis.
- Analysis of the cellular components and functions of skin dendritic cells.
- Examination of the interplay between dendritic cells and the IL-23/IL-17 axis.
Main Results:
- Dendritic cells are a significant cellular source of key cytokines like IL-23, tumor necrosis factor-α, and α-interferon.
- Specific DC subsets are implicated in initiating and perpetuating the inflammatory response characteristic of psoriasis.
- The IL-23/IL-17 axis is central to the immune dysregulation observed in psoriasis.
Conclusions:
- Dendritic cells play a pivotal role in the pathogenesis of psoriasis.
- Targeting pathogenic dendritic cell subsets presents a promising strategy for managing psoriasis and other dendritic cell-mediated disorders.

T Cell Types and Functions
2.0K
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.

Antigen Presenting Cells
2.8K
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

EPS and iPS Cells in Disease Research
3.3K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

T Cell Activation and Clonal Selection
14.5K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
