Summary
Endogenous lipid mediators like lipoxins, resolvins, and protectins are crucial for resolving inflammation. This review highlights their formation, action, and the role of eosinophils in controlling inflammatory responses.
Area of Science:
- Immunology
- Biochemistry
- Molecular Biology
Background:
- Acute inflammation is a vital immune response to injury or infection.
- In healthy individuals, inflammation is naturally resolved, indicating intrinsic control mechanisms.
- Understanding these resolution pathways is key to managing inflammatory diseases.
Purpose of the Study:
- To review recent advancements in the formation and function of endogenous lipid mediators.
- To emphasize the role of lipoxins, resolvins, and protectins in inflammation resolution.
- To explore the contribution of eosinophils and their derived mediators to inflammatory control.
Main Methods:
- Literature review of recent studies on inflammatory mediators.
- Focus on lipidomics approaches, specifically Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).
- Analysis of cellular and molecular events in inflammation and resolution.
Main Results:
- Endogenous lipid mediators derived from polyunsaturated fatty acids actively resolve inflammation.
- LC-MS/MS-based lipidomics provides powerful insights into mediator profiles.
- Eosinophils and their lipid mediators play significant roles in the resolution phase.
Conclusions:
- Lipoxins, resolvins, and protectins are critical for the self-limiting nature of acute inflammation.
- Advanced lipidomic techniques are essential for studying these mediators.
- Eosinophil-derived mediators represent a promising area for therapeutic intervention in inflammatory conditions.

01:28Inflammatory 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,...

01:26Acute 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...
01:26Acute Inflammation II: Cellular Phase
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...

Overview
01:12Chronic 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...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
