T-Cell Differentiation to T Helper 9 Phenotype is Elevated by Extremely Low-Frequency Electromagnetic Fields Via Induction of IL-2 Signaling.
This in vitro study examined 60 Hz extremely low-frequency EMF exposure (0.8 mT) on CD4 T cells under Th9-polarizing conditions. The authors report increased Th9-associated responses including IL-9 secretion, transcription factor changes (including early GATA3), and increased STAT5/STAT6 phosphorylation alongside increased IL-2 expression, suggesting involvement of IL-2 signaling. Co-culture experiments further reported increased mast cell activation markers and inflammatory cytokines when mast cells were cultured with EMF-exposed Th9 cells.
Key points
- The study tested 60 Hz ELF-EMF exposure at 0.8 mT on CD4 T cells under Th9-polarizing conditions.
- EMF exposure was reported to increase IL-9 secretion and Th9-related transcriptional markers.
- Early GATA3 expression and phosphorylation of STAT5 and STAT6 were reported to increase with EMF exposure.
- The authors report increased IL-2 expression and conclude the Th9 effect appeared dependent on IL-2 signaling.
- Co-cultures with mast cells showed higher expression of mast cell proteases and FcεR1α with EMF-exposed Th9 cells.
- Mast cell-derived inflammatory cytokine expression was reported to be higher in the EMF-exposed co-culture condition.
