Abstract

Excessive inflammation in the body causes immune cells to release cytokines that damage normal tissues and cells, leading to rheumatoid arthritis and sepsis. Pulsed magnetic field(PMF) stimulation has many applications in the treatment of neurological, muscular disorders and pain. Therefore, in this study, we aim to investigate the effect of PMF stimulation on the regulation of excessive inflammation in the overall immune system. Macrophages, a primary immune cell, and T cells, a secondary immune cell, were co-cultured in the insert wells under the same conditions, and then inflammation was artificially induced. The changes in inflammatory activity following PMF stimulation were measured by pH and IL-6 concentration. After inflammation induction, both cells became more acidic and increased IL-6 expression, but after PMF stimulation, we observed improved acidification of macrophages and T cells and decreased IL-6 expression. Our results showed that infected macrophages activated T cells and that the recovery of excessive inflammatory response regulation after PMF stimulation proceeded more rapidly in macrophages. Therefore, this study suggests that PMF has a positive anti-inflammatory effect on the overall immune system and thus has the potential to be used as a non-invasive therapy for the treatment of chronic inflammatory diseases.
