Altered serotonin (5-HT) neurotransmission has been implicated in the pathophysiology of migraine headache. To test this hypothesis in migraine patients in vivo using PET and alpha-[(11)C]methyl-l-tryptophan as a surrogate marker of brain 5-HT synthetic rate during different phases of their

We have previously demonstrated that mRNA expression and enzyme activity levels of placental indoleamine 2,3-dioxygenase (IDO), which degrades L-tryptophan and blocks the proliferation of T cells, are significantly low in patients with severe pre-eclampsia. From this observation, we hypothesized that

The development of nonradioactive and targeted magnetonanoparticles (MNP) capable of crossing the blood-brain barrier (BBB) and of concentrating in the epileptogenic tissues of acute and chronic animal models of temporal lobe epilepsy to render these tissues visible on magnetic resonance

Allo-reactive memory T cells are a major barrier for induction of immunological tolerance to allografts in humans. Here, we report that stimulation of unfractionated human T cells with TLR-stimulated allogeneic plasmacytoid dendritic cells (pDCs) induces CD8(+) regulatory T cells (Tregs)

In this study, we determined whether diffusion tensor imaging (DTI), a more widely available imaging modality, is as effective as α-[(11)C]methyl-l-tryptophan (AMT)-positron emission tomography (PET) in localizing epileptogenic tubers in tuberous sclerosis complex. Following that, coregistration of AMT-PET and diffusion
