title: T cell adhesion to the extracellular matrix proteins as a determinant of pregnancy success or failure.
abstract: Recent studies emphasize an important role of the extracellular matrix (ECM) proteins in the regulation of T cell function. The role of the T cell:ECM interaction during pregnancy has not been established yet. ECM proteins promote acquisition of the adhesive and degradive properties required by the embryo for successful implantation. T cells presented at the maternal-foetal interface may regulate the maternal immune response to the foetal allograft. T cell adhesion to collagen IV (C-IV), elastin (E) and fibronectin in 35 women with threatened abortion and in five normal pregnant women were studied. The relationship between T cell adhesion to ECM and pregnancy outcome was analyzed. Correlation between T cell adhesion to fibronectin and C-IV and pregnancy success or failure were observed. Our studies indicate that there is enhanced T cell adhesion to C-IV and fibronectin in women with unexplained threatened abortion, especially in those with a previous history of recurrent spontaneous abortion (RSA).
