Summary
The foreign body reaction (FBR) to implanted materials involves distinct phases regulated by soluble mediators. Understanding these mediators is crucial for managing FBR and improving medical device integration.
Area of Science:
- Biomaterials Science
- Immunology
- Tissue Engineering
Background:
- Implanted materials trigger an inflammatory response known as the foreign body reaction (FBR).
- The FBR progresses through distinct phases: onset, progression, and resolution, creating a dynamic microenvironment.
- Soluble mediators like cytokines, chemokines, and matrix metalloproteinases (MMPs) regulate FBR cellular processes.
Purpose of the Study:
- To review the key processes during FBR initiation, progression, and resolution.
- To emphasize the critical role of soluble mediators in the FBR.
- To explore the intricate relationship between FBR and soluble mediator expression.
Main Methods:
- Review of existing literature on the foreign body reaction.
- Focus on the subcutaneous implantation model.
- Analysis of the role of soluble mediators in regulating FBR phases.
Main Results:
- The FBR involves a complex cascade of cellular events orchestrated by soluble mediators.
- Spatial and temporal regulation of soluble mediators is essential for FBR progression.
- Limited knowledge exists regarding the precise interplay between FBR and mediator expression.
Conclusions:
- Soluble mediators are central regulators of the foreign body reaction.
- Further research is needed to elucidate the detailed mechanisms of mediator regulation in FBR.
- Understanding these interactions is vital for developing strategies to modulate FBR for better medical device outcomes.

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...
01:19Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
01:09Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
01:30Inflammatory Response I: Vascular and Cellular
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...
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...
01:24Inflammatory Response II: Inflammatory Exudate and Tissue Repair
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the exudate's...
