General description

Corticosterone (Cort) is a glucocorticoid hormone. It is also the principal hormone that mediates stress responses in birds. It is the primary adrenal cortical steroid in rat plasma. The influence of maternal Cort exposure on the developing placenta has been studied in a mouse model.

Application

Corticosterone was used to study the adrenoceptor signaling in rats, lizards or in vitro. It was also used in immune suppression experiment.

Biochem/physiol Actions

Corticosterone is synthesized from cholesterol in the adrenal cortex that activates both mineralocorticoid and glucocorticoid receptors. The role of corticosterones is vital for reproductive processes including ovulation, lutenization, development of oocytes, parturition and lactation. The metabolism of corticosterone is modulated by the enzyme 11β-hydroxysteroid dehydrogenase.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Preparation Note

Corticosterone is soluble in chloroform and ethanol.

Although naturally occurring hosts often exhibit pronounced differences in infection and pathology, the relative importance of factors associated with host life history and immunity in explaining such patterns often remains speculative. Research in eco-immunology highlights the trade-offs between host physiology
