The data showed that the electromagnetic field exposures did not have any effect on the cell viability, rates of apoptosis and the proliferation index. While electromagnetic field exposures did not affect the major histocompatibility complex class II and CD11b expressions in the peripheral blood mononuclear cells, they decreased the CD11a expression and increased the CD49d expression.
In conclusion, these findings suggest that electromagnetic fields could affect the functional capacity of the peripheral blood mononuclear cells by changing their adhesion ability.
