Hormones Immune cells Effect References
Estradiol (E2) Neutrophils Regulate the number and function Decrease chemotaxis by altering the expression of ICAM-1 Decrease superoxide anion production Produce cytokines TNF-a, IL-6, and IL-1beta [28-31]
Macrophages Increase macrophage phagocytic activity Increase CD14, LBP and TLR42 [32,33]
Dendritic cells Promote functional differentiation Increase the expression of MHC II, CD14, CD40, CD80, CD86, CXCL8 and CCL2 Induce IKDCs and increase nitric oxide [34-36]
NK cells Decrease cytotoxicity Upregulate the number of cells and expression of CD69, NKp46, NKG2DL, CD244, granzyme B and FasL [39,40]
Lymphocytes Upregulate T-bet expression (Th1 and proinflammatory cytokines) Increase IL-4 production from CD4+ T cells Decrease production of IL-17 Upregulate Treg cells (expression of Foxp3, IL-10 and PD-L1) Stimulate antibody production [42-49]
Progesterone (P4) Macrophages Inhibition classical pathway activation (iNOS and arginase activity) [61]
Dendritic cells Inhibit the activity of mature DCs Down-regulate TNF-α, IL-1β, MHC II, CD80 Inhibit DC-stimulated proliferation of T cells [62]
NK cells Regulate differentiation (Hox-A10) Reduce in cytotoxicity (HLA-G) Inhibit of perforin release (PIBF) Th2 differentiation and cytokine production (PIBF) [13,14,63,66]
Lymphocytes Promote differentiation of Th2 Induce migration of Treg cells to the pregnant uterus [13,181]
Testosterone Macrophages Inhibit the function of macrophages [12]
(T4)   Reduce TLR4 expression Inhibit NO production  
  APC’s Down-regulate IL-1β, IL-6 and TNF-α [70]
  Lymphocytes Reduce Th1 cytokine release Induce Th2 profile Maintain Treg cells [72,73]
DHEA Neutrophil Increase superoxide generation [75]
  Dendritic cells Induce mature DCs [76]
  Lymphocytes Enhance IL-2 secretion of Th1 cells and cytotoxicity function of T cells Induce apoptosis pathway Fas/Fas-L [77,78]
