Immune activation was induced through administration of Lipopolysaccharides LPS and the amounts of pro-inflammatory cytokines immune signaling molecules were measured. However, estrogen could attenuate the peripheral immune response in young females, but increased cytokine production from peripheral immune cells in aged females.

The authors also report that this effect is only found after chronic pretreatment, and mention unpublished results suggesting that acute estrogen treatment after inflammation has no effect.
