title: In vivo correlation between IL-1beta concentration in uterine fluid and integrin expression pattern in infertile women.
abstract: OBJECTIVE
  To evaluate the possible correlation between interleukin-1beta (IL-1beta) and integrin expression.
  
  
  METHODS
  Endometrium and uterine fluid from 77 infertile women and 24 fertile, healthy control were studied with immunohistochemistry and enzyme-linked immunosorbent assay for the presence of IL-1beta and integrin alphaVbeta3 and alpha4beta1 expression.
  
  
  RESULTS
  Highest expression of alphaVbeta3 was found in epithelium and glands in endometria from fertile women. There was no positive correlation between IL-1beta and integrin expression pattern.
  
  
  CONCLUSIONS
  This study confirms the importance of alphaVbeta3 as molecular marker of receptive phase. Also supports the views that synchrony in development of endometrium is necessary for successful nidation. There was however, contrary to results of previous in vitro studies, no positive correlation between IL-1beta and endometrial integrin patter expression.
