The balance between cell survival and death in the placenta: Do neurotrophins have a role?
Syst Biol Reprod Med. 2021 Oct 6:1-10. doi: 10.1080/19396368.2021.1980132. Online ahead of print.ABSTRACTNeurotrophins (NT) are a closely related family of growth factors, which regulate the nervous system's development, maintenance, and function. Although NTs have been well studied in neuronal cells, they are also expressed in the placenta. Despite their suggested role in regulating fetoplacental development, their precise functional significance in the placenta remains elusive. NT activate two different classes of receptors. These include the Trk, tropomyosin-related kinase family of high-affinity tropomyosin-related kin...

Adiponectin Inhibits Nutrient Transporters and Promotes Apoptosis in Human Villous Cytotrophoblasts: Involvement in the Control of Fetal Growth.
Abstract The placenta exchanges nutrients between the mother and the fetus, and requires a constant abundant energy supply. Adiponectin (a cytokine produced primarily by adipose tissue) controls glucose and lipid homeostasis. It is well known that maternal serum adiponectin levels are inversely related to birth weight suggesting that adiponectin has a negative effect on fetal growth. This effect appears to be related to the control of nutrient transporters in human placenta. However, the underlying molecular mechanisms have not yet been characterized. In the present work, we studied adiponectin's direct effect on ...
