title: Localisation of mRNAs for diamine oxidase and histamine receptors H1 and H2, at the feto-maternal interface of human pregnancy.
abstract: OBJECTIVE
  To localise mRNAs for the histamine receptors H1, H2 and H3, and for diamine oxidase, in the placenta and decidua of the human feto-maternal interface.
  
  
  METHODS
  Complementary DNA for each mRNA of interest was amplified by polymerase chain reaction. Sub-cloned sequences were used to prepare probes for in situ hybridisation, and these were employed to localise the expression of mRNAs for histamine receptors H1 and H2, and for diamine oxidase.
  
  
  RESULTS
  mRNA for histamine receptors H1 and H2, and for diamine oxidase could be detected at the feto-maternal interface of human pregnancy, and localised to both decidual and placental cells.
  
  
  CONCLUSIONS
  The co-expression of these receptors and DAO is consistent with a role for histamine at the feto-maternal interface of human pregnancy.
