Journal ArticleDOI
Neurosteroids, immunosteroids, and the Balkanization of endocrinology.
Kim L. Schmidt,Devaleena S. Pradhan,Amit H. Shah,Thierry Charlier,Eunice H. Chin,Kiran K. Soma +5 more
TL;DR: It is proposed that the shift to local synthesis and regulation of steroids within target tissues represents a "Balkanization" of the endocrine system, whereby individual tissues and organs may become capable of autonomously synthesizing and modulating local steroid signals, perhaps independently of the HPG and HPA axes.
Journal ArticleDOI
Aggressive interactions rapidly increase androgen synthesis in the brain during the non-breeding season
Devaleena S. Pradhan,Amy E. M. Newman,Douglas W. Wacker,John C. Wingfield,Barney A. Schlinger,Kiran K. Soma +5 more
TL;DR: The data suggest that territorial challenges rapidly increase endogenous NAD(+) levels or increase 3beta-HSD activity specifically within a NAD-rich subcellular compartment and suggest a shift from systemic to local sex steroid signaling in the non-breeding season.
Journal ArticleDOI
Dehydroepiandrosterone and corticosterone are regulated by season and acute stress in a wild songbird: jugular versus brachial plasma.
TL;DR: The data suggest that acute stress specifically affects the balance between DHEA synthesis and metabolism in the brain during molt, when systemic levels of CORT and D HEA are low.
Journal ArticleDOI
Rapid estrogen regulation of DHEA metabolism in the male and female songbird brain.
TL;DR: The first data to show a rapid effect of estrogens on the songbird brain are shown and suggest that rapid estrogen effects differ between male and female brains.
Journal ArticleDOI
3β-HSD activates DHEA in the songbird brain
TL;DR: Evidence that DHEA treatment can stimulate song behavior and the growth of neural circuits controlling song behavior is described, and brain 3β-HSD and aromatase can work in concert to locally metabolize D HEA into active androgens and estrogens, which are critical for controlling behavior and robust adult neuroplasticity in songbirds.
