The unhindered development of the fetal HPA axis is dependent on the function and activity of 11β-hydroxysteroiddehydrogenase type 2 (11β-HSD2), a transplacental cortisol barrier. (mcmaster.ca)
Decreased 11β-HSD2 levels in term born females may lead to an increased placental transfer of maternal cortisol and therefore result in a reduced head circumference and a higher risk for altered stress response in adulthood. (mcmaster.ca)
However, the role of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which catalyzes the conversion of inactive cortisone into active cortisol, in inflammation remains unclear. (ac.ir)
Furthermore, cortisone and cortisol, which are the substrate and product of 11β-HSD1, respectively, showed biphasic responses and induced the expression of pro-inflammatory cytokines at a low concentration in both LPS-stimulated or untreated THP-1 cells. (ac.ir)

Deficiency10
3-Beta-hydroxysteroid dehydrogenase (3BHSD) deficiency is a rare form of congenital adrenal hyperplasia that results in decreased production of all three groups of adrenal steroids: mineralocorticoids, glucocorticoids, and sex steroids. (medscape.com)
Although first described in male infants with ambiguous genitalia and severe salt wasting, 3-beta-hydroxysteroid dehydrogenase deficiency also occurs in 46,XX female infants (who may have mild clitoromegaly), as well as in older patients who present with a milder or so-called late-onset variant. (medscape.com)

A study in 2017 has shown that in subjects with 21-hydroxylase deficiency, serum 11β-OHP concentrations range from 0.012 to 3.37 ng/mL, while in control group it was below detection limit of 0.012 ng/mL. 21-hydroxylase is an enzyme that is also involved in progesterone metabolism, producing 11-deoxycorticosterone. (wikipedia.org)
verification needed] That's why in 21-hydroxylase deficiency, given the normal function of the CYP11B enzymes, the progesterone is directed towards 11β-OHP pathway rather than towards 11-deoxycorticosterone pathway, that is also usually accompanied by an increase in progesterone levels. (wikipedia.org)
In 21-hydroxylase deficiency, progesterone and 17α-hydroxyprogesterone accumulate and are the substrates of steroid 11β-hydroxylase, leading to 1β-OHP and 21-deoxycortisol, respectively. (wikipedia.org)
While studies suggest that 11β-OHP, also known as 21-deoxycorticosterone, can be used as marker for adrenal 21-hydroxylase deficiency, another 21-carbon steroid - 21-deoxycortisol (produced from 17α-hydroxyprogesterone) gained acceptance for this purpose. (wikipedia.org)
