Aims/hypothesis Pleiotrophin, a developmentally regulated and highly conserved cytokine, exerts different functions including regulation of cell growth and survival. Here, we hypothesise that this cytokine can play a regulatory role in glucose and lipid homeostasis. Methods To test this hypothesis, we performed a longitudinal study characterising the metabolic profile (circulating variables and...
Background Pleiotrophin (PTN) is a cytokine found highly upregulated in the brain in different disorders characterized by overt neuroinflammation such as neurodegenerative diseases, drug addiction, traumatic injury, and ischemia. In the present work, we have explored whether PTN modulates neuroinflammation and if Toll-like receptor 4 (TLR4), crucial in the initiation of an immune response, is involved...
The system KISS1–KISS1R is one of the main regulators of the hypothalamic-pituitary-gonadal axis and constitutes a link between metabolism and reproduction through its interaction with leptin. The aim of this study was to clarify the possible utility of kisspeptin as a pubertal marker and/or the possible influence of nutritional status in kisspeptin levels. To this end, we have studied kisspeptin...
Kisspeptin, the product of the hypothalamic KISS1 gene, is a main regulator of the hypothalamic–pituitary–gonadal axis and could be a link between metabolism and reproduction through its interaction with leptin. Kisspeptin could be involved in gonadotropin regulation and responsive to leptin levels from the first stages of life, exhibiting, as does leptin, sexual dimorphism. To test our hypothesis,...
