Purpose of Review Preeclampsia affects 3–4% of pregnancies with few treatment options to reduce maternal and fetal harm. Recent evidence that targeting the complement system may be an effective therapeutic strategy in prevention or treatment of preeclampsia will be reviewed. Recent Findings Studies in humans confirm the safety and efficacy of C5 blockade in complement-mediated disorders of pregnancy,...
Toll-like receptors (TLRs) are an essential component of the innate immune system. While a number of studies have described TLR expression in the female reproductive tract, few have examined the temporal expression of TLRs within the human placenta. We hypothesized that the pattern of TLR expression in the placenta changes throughout the first and second trimester, coincident with physiological changes...
The prevention of uterine infection is critical to appropriate fetal development and term delivery. The innate immune system is one component of the uterine environment and has a role in prevention of uterine infection. Natural antimicrobials are innate immune molecules with anti-bacterial, anti-viral and anti-fungal activity. We discuss two groups of natural antimicrobials in relation to pregnancy:...
Human histocompatibility leukocyte antigen (HLA)-G is an antigen-presenting molecule. This review discusses the possibility that this might not be its primary function. HLA-G indeed modulates innate immunity by interacting with immunoglobulin-like receptors and by regulating HLA-E expression and its subsequent interaction with CD94/NKG2 receptors. HLA-G also down-modulates both CD8 + and CD4...
