Abstract
Advanced urothelial bladder cancer (UBC) patients are tagged by a dismal prognosis and high mortality rates, mostly due to their poor response to standard-of-care platinum-based therapy. Mediators of chemoresistance are not fully elucidated. This work aimed to study the metabolic profile of advanced UBC, in the context of cisplatin resistance. Three isogenic pairs of parental cell lines (T24, HT1376 and KU1919) and the matching cisplatin-resistant (R) sublines were used. A set of functional assays was used to perform a metabolic screening on the cells. In comparison to the parental sublines, a tendency was observed towards an exacerbated glycolytic metabolism in the cisplatin-resistant T24 and HT1376 cells; this glycolytic phenotype was particularly evident for the HT1376/HT1376R pair, for which the cisplatin resistance ratio was higher. HT1376R cells showed decreased basal respiration and oxygen consumption associated with ATP production; in accordance, the extracellular acidification rate was also higher in the resistant subline. Glycolytic rate assay confirmed that these cells presented higher basal glycolysis, with an increase in proton efflux. While the results of real-time metabolomics seem to substantiate the manifestation of the Warburg phenotype in HT1376R cells, a shift towards distinct metabolic pathways involving lactate uptake, lipid biosynthesis and glutamate metabolism occurred with time. On the other hand, KU1919R cells seem to engage in a metabolic rewiring, recovering their preference for oxidative phosphorylation. In conclusion, cisplatin-resistant UBC cells seem to display deep metabolic alterations surpassing the Warburg effect, which likely depend on the molecular signature of each cell line.

Abstract
Pattern recognition receptors (PRRs) are responsible for Aspergillus fumigatus recognition by innate immunity and its subsequent immune signaling. The triggering receptor expressed on myeloid cells 1 (TREM1) is a recently characterized pro-inflammatory receptor constitutively expressed on the surface of neutrophils and macrophages. A soluble form (sTREM1) of this protein that can be detected in human body fluids has been identified. Here we investigated the role of TREM1 during invasive pulmonary aspergillosis (IPA). IPA patients displayed significantly higher levels of sTREM1 in bronchoalveolar lavages when compared to control patients. Functional analysis in TREM1 showed that the levels of sTREM1 and TREM1 pathway-related cytokines were influenced by single nucleotide polymorphisms in TREM1. In addition, we confirmed a role of TREM1 on antifungal host defense against A. fumigatus in a murine model of IPA. TREM1 deficiency increased susceptibility to infection in the immunosuppressed murine host. Deletion of TREM1 showed delayed innate and adaptive immune responses and impaired pro-inflammatory cytokine responses. The absence of TREM1 in primary macrophages attenuated the TLR signaling by altering the expression of both receptor and effector proteins that are critical to the response against A. fumigatus. In this study, and for the first time, we demonstrate the key role for the TREM1 receptor pathway during IPA.

Abstract
INTRODUCTION Uremic toxins play a pivotal role in the development of systemic complications of chronic kidney disease (CKD), which are largely mediated by the activation of the immune system. Triggers of inflammation in CKD are largely unknown and strategies aiming to reduce circulating ligands that could start the inflammatory response are potentially important. In the present study, we investigated the impact of sevelamer hydrochloride treatment in reducing endotoxemia and inflammation in a group of hemodialysis (HD) patients. MATERIAL AND METHODS HD patients, who were converted from calcium carbonate treatment to sevelamer according to KDOQI guidelines, were included and prospectively followed for 6 months. Systemic inflammation was evaluated by serum ultra-high-sensitivity C-reactive protein (hsCRP) using an automated immunoturbidimetric assay. Endotoxin was measured using Limulus amebocyte lysate chromogenic endpoint assay. All the analyses were performed immediately before conversion and after 6 months of treatment. RESULTS After the exclusion of patients discontinuing the treatment, 20 patients (mean dialysis time 12 +/- 4 months on HD, age 52 +/- 2 years, 38% males, 11% diabetics) were included in the analysis. No significant changes were observed in Ca, P and PTH levels, while a reduction in cholesterol levels was seen. Plasma concentration of hsCRP and endotoxin significantly decreased after 6 months of conversion to sevelamer compared with baseline. CONCLUSION We conclude that sevelamer treatment leads to a decrease in hsCRP levels, which was accompanied by a parallel decrease in endotoxemia, suggesting that endotoxemia may contribute to the systemic inflammation in HD patients, which was partially reduced by the use of sevelamer.
