AIM OF THE STUDY Silybum marianum (milk thistle) is a Mediterranean plant that has been used since Greco-Roman times to treat liver ailments. Silibinin, the most active hepatoprotective constituent of the plant's seed, possesses antioxidant and anti-inflammatory properties. We thus assessed its protective potential in liver transplantation injury. (More)
Indoleamine 2,3-dioxygenase 1 (Ido1) is a rate-limiting enzyme that catalizes the degradation of tryptophan along the kynurenine pathway. Here, we show that Ido1 activity sustains an immunostimulatory potential through inhibition of interleukin (Il)10. In atherosclerosis, Ido1-dependent inhibition of Il10 translates into disease exacerbation. The resistance(More)
BACKGROUND The posttransplant period following hematopoietic stem cell transplantation (HSCT) is potentially high risk for developing survival-compromising complications, many of which are known to be under the control of immunogenetic factors. Given the dual role of human leukocyte antigen (HLA)-E molecules in innate and adaptive immune processes, we(More)
AIM Nigella sativa (N. sativa) is a plant widely used in traditional medicine of North African countries. During the last decade, several studies have shown that extracts from the seeds of N. sativa have antidiabetic effects. METHODS Our group has recently demonstrated that N. sativa seed ethanol extract (NSE) induces an important insulin-like stimulation(More)
RATIONALE Necrotic core formation during the development of atherosclerosis is associated with a chronic inflammatory response and promotes accelerated plaque development and instability. However, the molecular links between necrosis and the development of atherosclerosis are not completely understood. Clec9a (C-type lectin receptor) or DNGR-1 (dendritic(More)
