IL-17-producing CD4+ T lymphocytes (Th17) are currently considered relevant participants in the pathogenesis of psoriasis skin lesions. However, little is known about potential role CD8+ cells, which also present at psoriatic plaque. We have addressed functional characterization this subtype from patients. Our results show that CD8+IL-17+ cells psoriasis-inflamed tissue produce TNF-alpha and IFN-gamma (Th1-related cytokines) as well IL-17, IL-21, IL-22 (Th17-related efficiently. A...

Hepatoblastoma (HB) is a rare disease. Nevertheless, it the predominant pediatric liver cancer, with limited therapeutic options for patients aggressive tumors. Herein, we aimed to uncover mechanisms of HB pathobiology and identify new biomarkers targets in move towards precision medicine advanced HB.We performed comprehensive genomic, transcriptomic epigenomic characterization 159 clinically annotated samples from 113 HB, using high-throughput technologies.We discovered widespread...

The European Liver Transplant Registry (ELTR) has collected data on liver transplant procedures performed in Europe since 1968.Over a 50-year period (1968-2017), clinical and laboratory were from 133 centers analyzed retrospectively (16,641 transplants 14,515 children). Data according to three successive periods (A, before 2000; B, 2000-2009; C, 2010), studying donor graft characteristics outcome. use of living donors steadily increased A C n = 296 [7%]; 1131 [23%]; 1985 [39%]; p 0.0001)....

Livers from donation after circulatory death (DCD) donors are an increasingly more common source of organs for transplantation. While there few high-level studies in the field DCD liver transplantation, clinical practice has undergone progressive changes during past decade, particular due to mounting use postmortem normothermic regional perfusion (NRP). In Spain, uncontrolled been performed since late 1980s/early 1990s, while controlled was implemented nationally 2012. Since 2012, rise...

SUMMARY Dysfunction of cytotoxic activity T and natural killer (NK) lymphocytes is a main immunological feature in patients with AIDS, but its basis are not well understood. It has been recently described that NK cell-mediated cytotoxicity can be regulated by HLA inhibitory receptors (KIR). In this work, we have determined on cells from HIV-1-infected individuals the expression following KIR molecules: p58, p70, ILT2 (immunoglobulin-like family KIR) as CD94 NKG2A (C-lectin-type KIR). With...

Defective T cell functions, including IL-2 production and proliferation, have been shown in SLE patients. After stimulation (first signal), a costimulatory signal (second signal) is required to achieve complete activation. Main signals are provided cells by B7 antigens (CD80 CD86, expressed on antigen-presenting (APC)) upon interaction with its receptor, the CD28 molecule cells. The aim of this study was investigate role CD28/B7 interactions impaired responses We show that...
