title: Immune interactions at the maternal-fetal interface: a focus on antigen presentation.
abstract: OBJECTIVE
  Viruses and fetuses face similar immunologic challenges. Each must evade immune detection and destruction. The virus must avoid host recognition of intracellular infection; the fetus allogenic recognition. Each has manipulated the process of antigen presentation to allow survival in an immunologic environment otherwise predictably hostile. How have these approaches co-evolved? What can they teach us about viral pathogenesis and immunologic interactions at the maternal-fetal interface?
  
  
  METHODS
  Review of relevant literature.
  
  
  RESULTS
  Special classical and non-classical MHC class I products are spared from downregulation in the placenta and from viral immunoevasive strategies.
  
  
  CONCLUSIONS
  Viruses rely upon some of the same strategies to avoid immune detection as do trophoblast cells. In the future, viral infections may prove a useful tool for studies of immunology at the maternal-fetal interface.
