Effects of Different Low-Frequency Electromagnetic Fields on Lymphocyte Activation: At which Cellular Level?

It has been shown that low-frequency electromagnetic fields may inhibit or enhance the lymphocyte response to many mitogens. How this happens is not known, and many reports suggest that alterations of surface receptors may be involved. Results presented here indicate that cellular activation is inhibited by a high-intensity EMF after the early phases of signal transduction, but it may be enhanced by a low-intensity EMF.
