Figure 1. Fetal lung surfactant protein A (SP-A) is first detectable in the amniotic fluid (AF) after approximately 80% of gestation is completed. Beginning at that time, levels rise dramatically until labor. SP-A binds toll-like receptors (TLRs) on AF macrophages and, via NF-?B, elicits an inflammatory response. Further, SP-A-stimulated AF macrophages migrate to the uterus and increase uterine contractility.
