Summary
Eicosanoids, derived from arachidonic acid, are key players in skin conditions like psoriasis. Recent research highlights their role in psoriasis pathogenesis and potential therapeutic targets.
Area of Science:
- Biochemistry
- Dermatology
- Molecular Biology
Background:
- Arachidonic acid (5,8,11,14-eicosatetraenoic acid C20:4, n-6) is a fatty acid released from cell membranes.
- Eicosanoids, metabolites of arachidonic acid, include prostaglandins, thromboxanes, leukotrienes, and hydroxyeicosatetraenoic acids.
- These compounds modulate various physiological and pathological processes in human skin.
Purpose of the Study:
- To review recent advancements in understanding the significance of eicosanoids in psoriasis pathogenesis.
- To explore how molecular biology developments have renewed interest in eicosanoids' role in psoriasis.
- To present new insights into psoriasis etiology and treatment based on eicosanoid biology.
Main Methods:
- Literature review focusing on recent progress in eicosanoid research related to psoriasis.
- Analysis of molecular biology developments impacting the understanding of eicosanoids.
- Synthesis of information on psoriasis etiology and treatment advances linked to eicosanoid biology.
Main Results:
- Eicosanoids are implicated as mediators or modulators in normal and diseased human skin.
- Phenomena observed in psoriasis can be explained, in part, by eicosanoid actions.
- Recent molecular biology findings have revitalized the study of eicosanoids in psoriasis.
Conclusions:
- Eicosanoids play a significant role in the pathogenesis of psoriasis.
- Advances in eicosanoid biology offer new understanding of psoriasis etiology.
- Progress in eicosanoid research may lead to novel therapeutic strategies for psoriasis.

Overview
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...
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,...

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.

Acute Inflammation I: Inflammatory Response
Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
