“…Using a murine model of perinatal infection (endotoxic lipopolysaccharide (LPS)-induced inflammation), in 2021, Panja et al [ 2 ] administered LPS to pregnant mice at the time of blastocyst implantation, which is a naturally occurring pro-inflammatory event provoked by the semi-allogeneic blastocyst, to distinguish between the natural event and the infectious circumstance. Their data suggest that neutrophils are not involved in the MyD88 pathway inflammatory cascade initiated by LPS induction.…”
