Project description:Candida tropicalis clinical isolate #12584 was spread on YPD plate supplemented with 40ng/ml of aureobasidin A. Randomly 18 adaptors were selected. Eight adaptors obtained tolerance. We sequenced the tolerant adaptors.

Project description:Pregnant CD-1 mice were fed control (ad libitum) and 70% total food (g) (MNR) diets from E6.5-birth. At birth, litters with 11-15 pups were cross-fostered to ad libitum-fed mothers. At weaning, males were kept for analysis and fed ad libitum until 6 months when they were euthanized by CO2 necropsis for quadriceps femoris, right medial liver lobe and perigonadal adipose tissue. Tissues were frozen in liquid nitrogen until total RNA isolations were done on whole-tissue homogenate. Libraries were made with polyA enrichment and sequenced. Differential expression between maternal nutrition or glucose tolerance groups (glucose intolerant MNR, tolerant MNR, MNR with a high fasting blood glucose [IFBG] and controls).

Project description:In clinical organ transplantation complete cessation of immunosuppressive therapy can be successfully accomplished in selected recipients providing a proof-of-principle that allograft tolerance is attainable in humans. The intra-graft molecular pathways associated with human allograft tolerance, however, have not been comprehensively studied before. In this study we analyzed sequential liver tissue samples collected from liver recipients enrolled in a prospective multicenter immunosuppressive withdrawal clinical trial. Tolerant and non-tolerant recipients differed in the intra-graft expression of genes involved in the regulation of iron homeostasis.These results point to a critical role of iron homeostasis in the regulation of intra-graft alloimmune responses in humans and provide a set of novel biomarkers to conduct drug-weaning trials in liver transplantation. The complete database comprised the expression measurements of 54,675 genes for liver inmunotolerance groups: 9 Tolerant (TOL) 10 Non Tolerant (Non TOL).A subset of 5 tolerant samples (TOL POST) were taken 1 year after inmunosuppresive therapy.

Project description:Transplant recipients spontaneously accepting their grafts in the absence of immunosuppression demonstrate the feasibility of attaining allograft tolerance in humans. Previous studies have identified blood transcriptional and cell phenotypic markers specific for either liver or kidney tolerant recipients, but the two settings have not been directly compared yet employing the same platforms. To identify potential similarities in immune parameters between recipients tolerant to different organs, we analyzed blood samples from tolerant and non-tolerant liver and kidney recipients employing whole genome expression microarrays. Tolerant and non-tolerant liver and kidney recipients differed in their peripheral blood expression patterns, but no significant overlap was observed between the two datasets. This was confirmed at the functional level by employing gene set enrichment analysis.The lack of obvious similarities in immune parameters associated with liver and kidney tolerant recipients implies the involvement of different mechanisms in the two settings and argues against the existence of a common immunological constant of spontaneous operational tolerance in clinical transplantation.

Project description:Bacterial persisters, a subpopulation of genetically susceptible cells that are normally dormant and tolerant to bactericides, have been studied extensively because of their clinical importance. In comparison, much less is known about the determinants underlying fungicide-tolerant fungal persister formation in vivo. Here, we report that during mouse lung infection, Cryptococcus neoformans forms persisters that are highly tolerant to amphotericin B (AmB), the standard of care for treating cryptococcosis. By exploring stationary-phase indicator molecules and developing single-cell tracking strategies, we show that in the lung, AmB persisters are enriched in cryptococcal cells that abundantly produce stationary-phase molecules. The antioxidant ergothioneine plays a specific and key role in AmB persistence, which is conserved in phylogenetically distant fungi. Furthermore, the antidepressant sertraline shows potent activity specifically against cryptococcal AmB persisters. Our results provide evidence for and the determinant of AmB-tolerant persister formation in pulmonary cryptococcosis, which has potential clinical significance.
