T Cell Types and Functions01:24

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 Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Inflammatory Response01:28

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,...
Chronic Inflammation: Introduction01:12

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...

Summary

Pulsed electromagnetic fields (PEMF) therapy reduces inflammatory cytokines (IL-1β, TNF-α) and increases IL-10 in fibroblast-like cells. This PEMF mechanism may explain its clinical benefits for osteoarticular conditions.

Area of Science:

  • Biomedical Engineering
  • Cell Biology
  • Immunology

Background:

  • Pulsed electromagnetic fields (PEMF) are clinically used for osteoarticular pathologies, but their mechanisms remain unclear.
  • Fibroblast-like cells derived from human peripheral blood mononuclear cells (MNC) offer a model to study cellular responses to PEMF.
  • Understanding PEMF's cellular effects is crucial for optimizing osteoarticular treatment.

Purpose of the Study:

  • To investigate the effects of a novel PEMF protocol on fibroblast-like cells derived from human peripheral blood MNC.
  • To analyze changes in immunophenotype and cytokine production following PEMF treatment.
  • To correlate cellular responses with the known clinical efficacy of PEMF in osteoarticular conditions.

Main Methods:

  • Fibroblast-like cells were cultured from human peripheral blood MNC.
  • Cells were exposed to a specific PEMF protocol (2.25 mT, 50 Hz, 15 min on days 7, 8, 9).
  • Immunophenotyping (Vimentin, Cytokeratin, CD34, CD41, CD61, CD68) and cytokine analysis (IL-1β, TNF-α, IL-10) were performed using Luminex technology.

Main Results:

  • PEMF treatment did not induce significant changes in the immunophenotype of the fibroblast-like cells.
  • Pro-inflammatory cytokines (IL-1β, TNF-α) significantly decreased in PEMF-treated cells on days 14 and 21.
  • The anti-inflammatory cytokine IL-10 significantly increased on day 21 in the PEMF-treated group.

Conclusions:

  • PEMF irradiation does not alter the immunophenotype of fibroblast-like cells.
  • PEMF treatment modulates cytokine production, reducing inflammation and potentially enhancing immune regulation.
  • These findings provide a cellular basis for the clinical effectiveness of PEMF in osteoarticular diseases.
