kynurenine and Pregnancy

kynurenine has been researched along with Pregnancy in 132 studies

Kynurenine: A metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
kynurenine : A ketone that is alanine in which one of the methyl hydrogens is substituted by a 2-aminobenzoyl group.

Pregnancy: The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.

Research Excerpts

ExcerptRelevanceReference
"There is now some evidence that i) the availability of plasma tryptophan, the precursor of serotonin, is significantly lower in pregnant women at the end of term and the first few days after delivery than in nonpregnant women; and ii) both pregnancy and the early puerperium are accompanied by activation of the inflammatory response system."9.10Depressive and anxiety symptoms in the early puerperium are related to increased degradation of tryptophan into kynurenine, a phenomenon which is related to immune activation. ( Bonaccorso, S; Bosmans, E; Maes, M; Ombelet, W; Scharpé, S; Verkerk, R, 2002)
"We hypothesize that: (1) L-tryptophan (Trp) is greatly utilized and not depleted in pregnancy; (2) fetal tolerance is achieved in part through immunosuppressive kynurenine (Kyn) metabolites produced by the flux of plasma free (non-albumin-bound) Trp down the Kyn pathway; (3) the role of indoleamine 2,3-dioxygenase (IDO) in infection is not related to limitation of an essential amino acid, but is rather associated with stress responses and the production of Kyn metabolites that regulate the activities of antigen presenting cells and T-cells, as well as increased NAD(+) synthesis in IDO-expressing cells; (4) Trp depletion is not a host defence mechanism, but is a consequence of Trp utilization."8.93The end of the road for the tryptophan depletion concept in pregnancy and infection.
