Caspases and apoptosis are thought to play a role in infection-associated preterm-delivery.
We have shown that in vitro treatment with pancaspase inhibitor Z-VAD-FMK protects trophoblasts from microbial antigen-induced apoptosis.
Objective.
To examine whether in vivo administration of Z-VAD-FMK would prevent infection-induced preterm-delivery.
Methods.
We injected 14.5 day-pregnant-mice with heat-killed group B streptococcus (HK-GBS).
Apoptosis within placentas and membranes was assessed by TUNEL staining.
Calpain expression and caspase-3 activation were assessed by immunohistochemistry.
Preterm-delivery was defined as expulsion of a fetus within 48 hours after injection.
Results.
Intrauterine (i.u.) or intraperitoneal (i.p.) HK-GBS injection led to preterm-delivery and induced apoptosis in placentas and membranes at 14 hours.
The expression of calpain, a caspase-independent inducer of apoptosis, was increased in placenta.
Treatment with the specific caspase inhibitor Z-VAD-FMK (i.p.) prior to HK-GBS (i.p.) delayed but did not prevent preterm-delivery.
Conclusion.
Caspase-dependent apoptosis appears to play a role in the timing but not the occurrence of GBS-induced preterm delivery in the mouse.
