Effects of in-utero and Early life Exposure to Wi-Fi Signals on the Immune System of C57BL/6 Mice

The impact Wi-Fi exposure was investigated on the developing immune system of C57BL/6 mice. A daily 2-hour whole-body exposure was carried out at 2.45 GHz and lasted 7 weeks. Dams were exposed for 2 weeks in utero and then pups for 5 weeks post-natal. The free-running animal exposure system was a reverberation chamber with SAR levels of 0, 0.8, 0.4, and 4 W/kg. The biological parameters evaluated were: number and sub-cellular phenotype of total splenocytes, lymphocyte proliferation, NK cell number and cytotoxicity, and expression pattern of cytokines (IFN-γ, TNFα, Il-2) and activation markers (CD25, CD69).
