Autophagy/Apoptosis Balance During Pregnancy

Autophagy/Apoptosis Balance During Pregnancy

The object of this study is to assess the intra- and inter-individual variability of apoptosis and autophagy activities in women during pregnancy: 1 / in women with a normal pregnancy and 2 / in pregnant women particularly at risk of complications.

The study investigators hypothesize that there would be an intra-trophoblastic dialogue between the mechanisms of autophagy and apoptosis, the promotion of one partially inhibiting the other. The increase in trophoblastic autophagy during pregnancy could thus constitute an anti-apoptosis defense phenomenon, the exhaustion of which would lead to cellular apoptosis and to pathogenic consequences when it devastates the syncytiotrophoblast.
