The Effect of a “Zero” Magnetic Field on the Production of Reactive Oxygen Species in Neutrophils

详细

Exposure of mouse peritoneal neutrophils to hypomagnetic conditions (magnetic shielding, a residual static magnetic field of 20 nT) for 1.5 h decreased the level of intracellular reactive oxygen species as recorded by changes in the fluorescence intensity of 2,7-dichlorodihydrofluorescein and dihydrorhodamine 123 oxidation products. The effect of a hypomagnetic field was similarly observed after adding a respiratory burst activator (the formylated peptide N-formyl–Met–Leu–Phe or phorbol 12-meristate-13-acetate) to a low concentration.
