Neuroinflammation and comorbidity of pain and depression.
Houston, United States. In Pharmacol Rev, 31 Jan 2014
These mechanisms include direct effects of cytokines on the neuronal environment or indirect effects via downregulation of G protein-coupled receptor kinase 2, activation of the tryptophan-degrading enzyme indoleamine 2,3-dioxygenase that generates neurotropic kynurenine metabolites, increased brain extracellular glutamate, and the switch of GABAergic neurotransmission from inhibition to excitation.
Immunology of major depression.
München, Germany. In Neuroimmunomodulation, Dec 2013
The tryptophan/kynurenine metabolism is one of the indirect mechanisms because the enzyme indoleamine 2,3-dioxygenase - a key enzyme of this metabolism in the central nervous system - is driven by pro- and anti-inflammatory cytokines and degrades serotonin.
The role of placental indoleamine 2,3-dioxygenase in human pregnancy.
Hiroshima, Japan. In Obstet Gynecol Sci, Jul 2013
For the first time they showed that in the mammal the fetus does survive an immune attack mounted by the mother, and that the mechanism responsible for the survival depends on the fetus and placenta 'actively' defending itself from attack by maternal T cells by means of an enzyme indoleamine 2,3-dioxygenase (EC 18.104.22.168) dependent localised depletion of L-tryptophan.
The Control of the Specificity of CD4 T Cell Responses: Thresholds, Breakpoints, and Ceilings.
Rochester, United States. In Front Immunol, 2012
In the last decade, our laboratory has evaluated the mechanisms that underlie the preferential specificity of CD4 T cells and have discovered that both intracellular events within antigen presenting cells, particular selective DM editing, and intercellular regulatory pathways, involving IFN-γ, indoleamine 2,3-dioxygenase, and regulatory T cells, play a role in selecting the final peptide specificity of CD4 T cells.
Highlights of 10 years of immunology in Nature Reviews Immunology.
New Haven, United States. In Nat Rev Immunol, 2011
Highlights include our improved understanding of Toll-like receptor signalling, and of immune regulation mediated by regulatory T cells, indoleamine 2,3-dioxygenase, myeloid-derived suppressor cells and interleukin-10.
