Table I. Effects of neuroendocrine factors (steroid hormones) on immune and non-immune processes in the host.
As estrogens and mineralocorticoids have been shown to have immunostimulatory effects at lower concentrations, the referenced actions on immune cell activity include experiments using elevated concentrations of the hormone.
Steroid Hormone | Example | Function (Non-Immune) | Function (Immune) |
---|---|---|---|
Androgens | Testosterone, Dihydrotestosterone | Development of 2nd sexual characteristics (male) | Apoptosis of monocyte populations (Ref. 34) |
Estrogens | 17β-estradiol, Estriol | Development of 2nd sexual characteristics (female) | Suppression of neutrophil activity (Ref. 22) |
Glucocorticoids | Cortisol, Cortisone | Glucose metabolism, maturation of lung during fetal development | Proinflammatory cytokine inhibition, immune cell apoptosis (Ref. 56) |
Mineralocorticoids | Androstenedione | Maintenance of salt-water balance | Reduction of peripheral blood neutrophils (Ref. 19) |
Progestins | Progesterone | Embryo implantation, maintenance of pregnancy | Obstruction of neutrophil recruitment (Ref. 25) |
