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,...

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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Area of Science:

Immunology
Cell Biology
Nutritional Science

Background:

The immune system relies on complex cellular interactions and inflammatory processes for host defense.
Eicosanoids derived from arachidonic acid play key roles in inflammation and lymphocyte regulation.
Inappropriate immune activity contributes to numerous human disorders.

Purpose of the Study:

To investigate the impact of altering immune cell fatty acid composition on immune function.
To explore the roles of eicosanoids, docosanoids, and resolvins derived from various fatty acids.
To examine how changes in fatty acid content affect immune cell membrane properties and functions.

Main Methods:

Oral administration of fatty acids (arachidonic acid, EPA, DHA) to alter immune cell composition.
Analysis of eicosanoid, docosanoid, and resolvin production patterns.
Assessment of changes in phagocytosis, T-cell signaling, and antigen presentation.
Investigation of effects at the cellular membrane level, including lipid rafts and trafficking.

Main Results:

Altering immune cell fatty acid content modifies the production of inflammatory mediators.
Changes in fatty acid composition impact key immune functions like phagocytosis and T-cell activation.
These effects are linked to alterations in immune cell membrane structure and dynamics.

Conclusions:

Dietary fatty acids can modulate immune cell function by altering their membrane composition and mediator production.
EPA and DHA supplementation may offer novel strategies for regulating immune responses and inflammation.
Fatty acids are crucial for maintaining immune cell membrane integrity and function.
