Adrenocortical Zonation, Renewal, and Remodeling
The adrenal cortex is divided into concentric zones. In humans the major cortical zones are the zona glomerulosa, zona fasciculata, and zona reticularis. The adrenal cortex is a dynamic organ in which senescent cells are replaced by newly differentiated ones. This constant renewal facilitates organ remodeling in response to physiological demand for steroids. Cortical zones can reversibly expand...
متن کاملLipid zonation and phospholipid remodeling in nonalcoholic fatty liver disease
Nonalcoholic fatty liver disease (NAFLD) can progress from simple steatosis (i.e., nonalcoholic fatty liver [NAFL]) to nonalcoholic steatohepatitis (NASH), cirrhosis, and cancer. Currently, the driver for this progression is not fully understood; in particular, it is not known how NAFLD and its early progression affects the distribution of lipids in the liver, producing lipotoxicity and inflamm...
متن کاملAdrenocortical zonation results from lineage conversion of differentiated zona glomerulosa cells.
Lineage conversion of differentiated cells in response to hormonal feedback has yet to be described. To investigate this, we studied the adrenal cortex, which is composed of functionally distinct concentric layers that develop postnatally, the outer zona glomerulosa (zG) and the inner zona fasciculata (zF). These layers have separate functions, are continuously renewed in response to physiologi...
متن کاملTOWARDS AN INTEGRATED VIEW OF Wnt SIGNALING IN MOUSE ADRENOCORTICAL FUNCTIONAL ZONATION
The adrenal gland is composed of two ontogenetically and functionally distinct t issues, the medulla and the cortex. The cortex, the subject of the present art icle, forms the major part of the murine gland and is further organized into three concentric layers: the outer zona glomerulosa, the zona fasciculata and the innermost X-zone. Specific hormonal production is finely tuned in t ime and sp...
متن کاملHuman Adrenocortical Remodeling Leading to Aldosterone-Producing Cell Cluster Generation
Background. The immunohistochemical detection of aldosterone synthase (CYP11B2) and steroid 11β-hydroxylase (CYP11B1) has enabled the identification of aldosterone-producing cell clusters (APCCs) in the subcapsular portion of the human adult adrenal cortex. We hypothesized that adrenals have layered zonation in early postnatal stages and are remodeled to possess APCCs over time. Purposes. To in...
