DOI: 10.1002/mrd.22835
Abstract: Porcine conceptuses secrete pregnancy‐recognition signals (estrogens, including estradiol‐17β) that inhibit luteolysis, thereby prolonging progesterone production by corpora lutea. The supportive mechanism by which the conceptus also inhibits luteolysis is by shifting endometrial prostaglandin (PG) synthesis… read more here.

DOI: 10.1016/j.placenta.2018.06.308
Abstract: INTRODUCTION Glucose is the primary energy substrate for early conceptus development and, for the first 40 days of gestation, the equine conceptus depends solely on glucose available in the histotroph; thereafter, histotrophic glucose provision continues… read more here.

Abstract: Maternal recognition of pregnancy (MRP) and implantation involve appropriate interactions between the elongating conceptus and the receptive endometrium that will condition development of the feto-placental unit to term. Molecular mechanisms that take place at the… read more here.

DOI: 10.1038/srep40476
Abstract: Exosomes and microvesicles are extracellular vesicles released from cells and can contain lipids, miRNAs and proteins that affect cells at distant sites. Recently, microvesicles containing miRNA have been implicated in uterine microenvironment of pigs, a… read more here.

DOI: 10.1093/biolre/ioab186
Abstract: Establishment and maintenance of pregnancy in the pig is a complex process that relies on conceptus regulation of the maternal proinflammatory response to endometrial attachment. Following elongation, pig conceptuses secrete interferon gamma (IFNG) during attachment… read more here.

Calcium-binding proteins S100A8, S100A9, and S100A12: expression and regulation at the maternal-conceptus Interface in pigs†.

DOI: 10.1093/biolre/ioac039
Abstract: Among the many calcium-binding proteins, S100A8, S100A9, and S100A12 play important roles in inflammation, innate immunity, and antimicrobial function, but their expression, regulation, and function at the maternal-conceptus interface in pigs are not fully understood.… read more here.

Abstract: Abstract The maternal immune system tolerates semi-allogeneic placental tissues during pregnancy. Fas ligand (FASLG) and tumor necrosis factor superfamily 10 (TNFSF10) are known to be components of maternal immune tolerance in humans and mice. However,… read more here.

Abstract: Widespread regions of the southeast United States have soils, and hence forages, deficient in selenium (Se), necessitating Se supplementation to grazing cattle for optimal immune function, growth, and fertility. We have reported that supplementation with… read more here.

Abstract: In 1953, Sir Peter Medawar first recognized the allogeneic properties of a developing conceptus and rationalized that an "immune tolerant" physiological state must exist during pregnancy. Early theories speculated that the conceptus evaded the maternal… read more here.
