This animal study examined subchronic exposure to a 30 mT static magnetic field for 10 weeks in young and 36-month-old rats (n=27). The abstract reports decreased lymphocyte counts and increased NLR in both age groups, with PLR increases limited to young rats and platelet decreases reported in older rats. The authors interpret the findings as age-dependent immune/inflammation modulation, framing potential proinflammatory risk in younger animals and immunosuppressive/stress-related effects in older animals.

This in vitro study examined effects of moderate static magnetic field exposure on sympathetic neuron-like PC12 cells. The authors report a significant reduction in voltage-gated potassium (Kv) channel current density after 18 hours of exposure, with the reduction persisting after the field was removed. RNA sequencing identified 37 SMF-sensitive genes and pathway analyses suggested upregulation of signaling associated with reduced neuronal excitability.
