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

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

We studied the effect of 1-methyl-D-tryptophan, an inhibitor of indoleamine-2,3-dioxygenase, on the growth of transplanted hepatocarcinoma-29 in C3HA mice. Hepatocarcinoma-29 transplanted into the thigh muscles undergoes immunological rejection in more than 50% non-syngeneic recipients. Chronic local administration of 1-methyl-D-tryptophan promotes
