Full-text available
Systemic lupus erythematosus is a complex autoimmune disorder mostly mediated by B-cells in which costimulatory signals are involved. This immune dysregulation can cause tissue damage and inflammation of the kidney, resulting in lupus nephritis and chronic renal failure. Given the previous experience reported with CTLA4-Ig as well as recent underst...

Overcoming resistance is one of the most challenging features in current anticancer therapy. Autophagy is a cellular process that confers resistance in some advanced tumors, since it enables cancer cells to adapt to stressful situations, such as anticancer treatments. Hence, the inhibition of this cytoprotective autophagy leads to tumor cells sensi...

Achieving fast immunosuppression blood exposure after kidney transplantation is key to abrogating both preformed and de novo anti-donor humoral and cellular alloresponses. However, while tacrolimus (TAC) is the cornerstone immunosuppressant inhibiting adaptive alloimmunity, its blood exposure is directly impacted by different single-nucleotide poly...

The glycolytic modulator TP53-Inducible Glycolysis and Apoptosis Regulator (TIGAR) is overexpressed in several types of cancer and has a role in metabolic rewiring during tumor development. However, little is known about the role of this enzyme in proliferative tissues under physiological conditions. In the current work, we analysed the role of TIG...

Systemic Lupus Erythematosus is a highly complex and heterogeneous autoimmune disease mostly mediated by B-cells. It is characterized by circulating self-reactive antibodies that deposit forming immune complexes in kidney, leading to irreparable tissue damage, and resulting in Lupus Nephritis. In a NZB/WF1 mice model, we tested two different siRNA...

Donor/recipient molecular human leukocyte antigen (HLA) mismatch predicts primary B-cell alloimmune activation, yet the impact on de novo donor-specific T-cell alloimmunity (dnDST) remains undetermined. The hypothesis of our study is that donor/recipient HLA mismatches assessed at the molecular level may also influence a higher susceptibility to th...

Introduction: Tacrolimus is the backbone immunosuppressant after solid organ transplantation. Tacrolimus has a narrow therapeutic window with large intra- and inter-patient pharmacokinetic variability leading to frequent over- and under-immunosuppression. While routine therapeutic drug monitoring (TDM) remains the standard of care, tacrolimus pharm...
Article
Background The ability of dendritic cells (DCs) to regulate adaptive immunity makes them interesting cells to be used as therapeutic targets modulating alloimmune responses. Mycophenolic acid (MPA) is an immunosuppressor commonly used in transplantation, and its effect on DCs has not been fully investigated. Methods Monocyte-derived DCs were obtai...
Article
Tacrolimus (Tac) is the cornerstone calcineurin inhibitor in transplantation. Extended‐release Meltdose formulation (Tac‐LCP) offers better bioavailability compared to immediate‐release formulation (Tac‐IR). We postulated that the less fluctuating pharmacokinetic profile of Tac‐LCP might maintain a sustained inhibition of calcineurin activity (CNA)...

Many studies have shown both the CD28—D80/86 costimulatory pathway and the PD-1—PD-L1/L2 coinhibitory pathway to be important signals in modulating or decreasing the inflammatory profile in ischemia-reperfusion injury (IRI) or in a solid organ transplant setting. The importance of these two opposing pathways and their potential synergistic effect l...
Article
Background and Aims Considering the particular pharmacokinetic (PK) profile of mycophenolate (MMF/MPS) with the important contribution of enterohepatic recirculation (EHC) and the potential alteration in tacrolimus (TAC) exposure, a PK study in solid-organ transplant patients who had undergone intestinal resection was carried out. Method This is a...
Article
Rejection and toxicity occur despite monitoring of tacrolimus blood levels during clinical routine. The intracellular concentration in lymphocytes could be a better reflection of the tacrolimus exposure. Four extraction methods for tacrolimus in peripheral blood mononuclear cells were validated and evaluated with UHPLC-MS/MS. Methods based on prote...
Article
Background: Therapeutic drug monitoring of calcineurin inhibitor, tacrolimus (TAC), is routinely used in post-transplantation. Currently, measurement of calcineurin activity has been proposed as a promising clinical tool to evaluate efficacy and to optimize drug dosing. The main aim of our study was to develop a method to measure phosphatase calci...
Article
Full-text available
Lymphocyte activation is associated with rapid increase of both the glycolytic activator fructose 2,6-bisphosphate (Fru-2,6-P2) and the enzyme responsible for its synthesis, 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2). PFKFB3 gene, which encodes for the most abundant PFK-2 isoenzyme in proliferating tissues, has been found...
Article
Background Cardiovascular disease is the leading cause of morbidity and mortality in kidney transplant recipients. Several single nucleotide polymorphisms (SNPs) in the ANRIL gene pathway have been associated with cardiovascular events (CE). The main objective was to ascertain whether ANRIL (rs10757278) and CARD8 (rs2043211) SNPs could mediate susc...

Background: Linezolid or cotrimoxazole plus rifampicin (RIF) are alternative oral treatments for staphylococcal prosthetic joint infections when fluoroquinolones are not possible to use, but there is limited evidence about its activity. Objectives: We evaluated the efficacy of linezolid (LZD) and cotrimoxazole (SXT) alone and in combination with...
Article
In human cancers, TGF-β1 plays a dual role by acting as both a tumor suppressor and a promoter of tumor metastasis. Although TGF-β1 contributes to the metabolic reprogramming of cancer cells and tumor-associated stromal cells, little is known of the molecular mechanisms connecting this cytokine with enhanced glycolysis. PFKFB3 is a homodymeric bifu...

Background Patients undergoing conventional hemodialysis (C-HD) present a greater immuno-inflammatory state probably related to uremia, sympathetic nervous system (SNS) activation and /or membrane bioincompatibility, which could improve with a technique-switching to online hemodiafiltration (OL-HD). The antigen-independent pathway activation of thi...
