Abstract
The mechanism of maternal immunotolerance of the semiallogeneic fetus has been a matter of intense investigation. The tryptophan- degrading enzyme indoleamine 2,3-dioxygenase (IDO) is reported to be critically implicated. This article discusses findings pertaining to the role of IDO in pregnancy, its location at the feto-maternal interface, systemic induction of IDO in pregnancy and the association of IDO to spontaneous abortion and preeclampsia. Whereas there is a large body of evidence supporting the relevance of IDO as a key immunoregulatory factor in feto-maternal tolerance, open questions remain concerning as to its role.
Keywords: Feto-maternal tolerance, tryptophan catabolism, placenta, trophoblast, decidua, preeclampsia, spontaneous abortion

Interaction between drugs and endocrine diseases
The introduction of highly active antiretroviral therapy accelerated studies and our understanding on the interaction between pharmacological therapies and endocrine diseases. Drugs can precipitate endocrine via different mechanisms, including direct alteration of hormone production and secretion, dysregulation of hormonal axis, effects on hormonal transport, receptor-binding, and cellular signalling. Common drug-induced ...read more
