To read the full abstract: Proc Natl Acad Sci U S A. 2018; 115(17): E4091-E4100The hypothalamic-pituitary-adrenal axis is a critical neurohormonal network that regulates homeostasis and coordinates the stress response. Glucocorticoids (GCs) are critical for life and are key regulators of cognitive, metabolic and immunologic homeostasis (4). Clinical studies in healthy human subjects, usi...

To read the full abstract: Proc Natl Acad Sci U S A. 2017; 114(31): E6466-E6474Cortisol production is tightly regulated in a dynamic way within the hypothalamic-pituitary adrenal system, which seems further embedded in a wider steroidogenic regulatory network (SRN). Normally, the connection from ACTH to cortisol production is in line with the HPA axis, but there are stressful events, in which t...

To read the full abstract: Science. 2017; 357(6346)Current textbooks teach that adrenergic chromaffin cells of the adrenal medulla originate from a sympathoadrenal cell lineage of the neural crest nearby the dorsal aorta. Here, Furlan et al. demonstrate a novel origin of these neuroendocrine cells of the medulla arising predominantly from Schwamm cell precursors (SCP) of peripheral nerves. Prev...
