EFFECT OF ELECTROSTATIC FIELD ON PROLIFERATION AND CYTOKINE SECRETION OF MACROPHAGE CELLS

Electricity has been shown to exhibit significant effects on immunological responses in many studies. In this study, an electrostatic filed induced device was first applied to the macrophage cell culturing process. Mouse macrophage-like cells J774 A.1 were exposed to the electrostatic field of 1.5 kV for 1, 2, and 6 days, respectively. The results show that the electrostatic field can inhibit cell proliferation and TNF-α secretion in six days. Cell proliferation is decreased and TNF-α secretion is increased with increasing voltage applied from 0 kV to 0.8 kV and 1.2 kV of the electrostatic fields.
