The presence of a CD4+ CD25high CD45RO+ CD127high T-cell population correlates with the clinical status of kidney transplant recipients

Background: Recent data have suggested that a population of CD4+ CD25high T cells, phenotypically characterized by the expression of CD45RO and CD127, is significantly expanded in stable liver and kidney transplant recipients and represents alloreactive T cells. We analyzed this putative new alloreactive cellular marker in various groups of kidney transplant recipients. Patients and methods: Flow cytometry was used to analyze the expression of CD25, CD45RO and CD127 on peripheral CD4+ T cells. Of 73 kidney recipients, 59 had a stable graft function under standard immunosuppressive therapy (IS), 5 had biopsy-proven chronic humoral rejection (CHR), 8 were stable under minimal IS and one was an operationally "tolerant" patient who had discontinued IS for more than 3 years. Sixty-six healthy subjects (HS) were studied as controls. Results: Overall, the alloreactive T cell population was found to be significantly increased in the 73 kidney recipients (mean ± SE: 15.03 ± 1.04% of CD4+ CD25high T cells) compared to HS (5.93 ± 0.39%) (p <0.001). In the 5 patients with CHR, this population was highly expanded (31.33 ± 4.16%), whereas it was comparable to HS in the 8 stable recipients receiving minimal IS (6.12 ± 0.86%), in 4 patients who had been switched to sirolimus (4.21 ± 0.53%) as well as in the unique "tolerant" recipient (4.69%). Intermediate levels (15.84 ± 0.93%) were found in the 55 recipients with stable graft function on standard CNI-based IS. Regulatory T cells, defined as CD4+ CD25high FoxP3+ CD127low, were found to be significantly reduced in all recipients except in those with minimal or no IS, and this reduction was particularly striking in recipients with CHR. Conclusion: After kidney transplantation, an alloreactive T cell population was found to be significantly expanded and it correlates with the clinical status of the recipients. Interestingly, in stable patients with minimal (or no) IS as well as in patients on sirolimus, alloreactive T cells were comparable the healthy controls. Measuring circulating CD4+ CD25high CD45RO+ CD127high T cells may become a useful monitoring tool after transplantation.

Regulatory ambivalence and the limitations of pharmaceutical policy in Spain

Broadly speaking, pharmaceutical policy in Spain has been unable to control either the price or thevolume of drugs prescribed. Limited attempts have been made to bring together the regulation of thepharmaceutical market and policies, in pursuit of the desired goals of efficiency and quality. Thispaper assesses the regulation of the Spanish pharmaceutical market over the last two decades byexamining regulation and policy and the available empirical evidence on their appreciable effects,and presents recommendations for policy design. Our findings suggest that policies aiming to improveefficiency and quality have not managed to contain costs, while cost-effectiveness is still overlooked.We argue that future policies should encourage broader participation in the decision-making processesand promote a higher degree of competition, especially from generic drugs.

OS CONTRACTOS DE CONCESSÃO NO CONTEXTO DO SISTEMA DE NORMALIZAÇÃO CONTABILÍSTICA E DE RELATO FINANCEIRO

A mudança do normativo contabilístico ocorrido em 2009, alterou o paradigma de reconhecimento e mensuração de activos. Embora a natureza das operações contínua presente no processo contabilístico, muitas coisas foram alteradas tendo em conta a substância da informação e a sua realidade económica. O caso dos contratos de concessão é disto um bom exemplo. Há casos em que no normativo anterior eram reconhecidos como activos fixos tangíveis e actualmente são reconhecidos como intangíveis. O estudo em causa tem como objetivo principal analisar o conceito dos contratos de concessão, bem como os procedimentos para o reconhecimento, mensuração e divulgação nas demonstrações financeiras. Considerados activos intangíveis (de facto a entidade acaba por ter um “Direito” de explorar um determinado activo), o processo contabilístico é feito a luz do disposto na Norma de Relato Financeiro nº6 – Activos Intangíveis. Os contractos de concessão apresentam especificidades próprias e por esta razão o IASB emitiu uma IFRIC (nº 12) com o objectivo de clarificar o tratamento contabilístico desta problemática. Não existindo no normativo nacional tal norma interpretativa as empresas nacionais que convivem com esta realidade vêem-se na contingência de, supletivamente, recorrer às normas internacionais de contabilidade para resolver o assunto. É o caso da ELECTRA para os activos afectos a distribuição. Neste sentido, o estudo debruça sobre esta problemática, apresenta um enquadramento teórico, analisar os principais aspectos de reconhecimento a luz dos dois normativos contabilísticos nacionais (o antigo Plano Nacional de Contabilidade e o actual Sistema de Normalização Contabilística e de Relato Financeiro) e termina utilizando as informações da ELECTRA, SARL para ilustrar este processo de reconhecimento contabilístico. The change of a the accounting regulatory occurred in 2009, changed the paradigm for recognizing and measuring assets. Although the continuous nature of the operations in this accounting process, many things have changed in view of the substance of information and its economic reality. The case of concession contracts, it is a good example. There are cases where the former were recognized as legal and tangible fixed assets are currently recognized as intangible assets. The study is aimed to analyzing the concept of concession contracts, as well as procedures for the recognition, measurement and disclosure in the financial statements. Considered intangible assets (in fact the entity turns out to have a “right” to exploit a particular asset) the accounting process is done in light of the provisions of Financial Reporting Standard No. 6 – Intangible Assets. The concession contracts have specific characteristics and for this reason the IASB issued IFRIC one (Ner. 12 ) in order to clarify the accounting treatment of this problem. In the absence of such a standard national regulatory interpretative national companies that live with this reality find themselves in contingency, additionally, make use of international accounting standards to resolve the matter. ELECTRA is the case of the assets connected to the distribution. In this sense, the study focuses on this issue, presents a theoretical framework to analyze the main aspects of recognition light of both national accounting standards (formerly the National Accounting Standards and the current system of accounting and financial reporting) and ends up using the information the Electra SARL to illustrate this process of accounting recognition.

Regulatory B cells shape the development of Th2 immune responses in BALB/c mice infected with Leishmania major through IL-10 production.

Recent evidence indicates that B cells are required for susceptibility to infection with Leishmania major in BALB/c mice. In this study, we analyzed the role of the IL-10 produced by B cells in this process. We showed that B cells purified from the spleen of BALB/c mice produced IL-10 in response to stimulation with L. major in vitro. In vivo, early IL-10 mRNA expression is detected after L. major infection in B cells from draining lymph nodes of susceptible BALB/c, but not of resistant C57BL/6 mice. Although adoptive transfer of naive wild-type B cells prior to infection in B cell-deficient BALB/c mice restored Th2 cell development and susceptibility to infection with L. major of these otherwise resistant mice, adoptive transfer of IL-10(-/-) B cells mice did not. B cells stimulated by L. major, following in vitro or in vivo encounter, express the CD1d and CD5 molecules and the IL-10 produced by these cells downregulate IL-12 production by L. major-stimulated dendritic cells. These observations indicate that IL-10 secreting B cells are phenotypically and functionally regulatory B cells. Altogether these results demonstrate that the IL-10 produced by regulatory CD1d+ CD5+ B cells in response to L. major is critical for Th2 cell development in BALB/c mice.

Isolating DNA from sexual assault cases: a comparison of standard methods with a nuclease-based approach.

AbstractText BACKGROUND: Profiling sperm DNA present on vaginal swabs taken from rape victims often contributes to identifying and incarcerating rapists. Large amounts of the victim's epithelial cells contaminate the sperm present on swabs, however, and complicate this process. The standard method for obtaining relatively pure sperm DNA from a vaginal swab is to digest the epithelial cells with Proteinase K in order to solubilize the victim's DNA, and to then physically separate the soluble DNA from the intact sperm by pelleting the sperm, removing the victim's fraction, and repeatedly washing the sperm pellet. An alternative approach that does not require washing steps is to digest with Proteinase K, pellet the sperm, remove the victim's fraction, and then digest the residual victim's DNA with a nuclease. METHODS: The nuclease approach has been commercialized in a product, the Erase Sperm Isolation Kit (PTC Labs, Columbia, MO, USA), and five crime laboratories have tested it on semen-spiked female buccal swabs in a direct comparison with their standard methods. Comparisons have also been performed on timed post-coital vaginal swabs and evidence collected from sexual assault cases. RESULTS: For the semen-spiked buccal swabs, Erase outperformed the standard methods in all five laboratories and in most cases was able to provide a clean male profile from buccal swabs spiked with only 1,500 sperm. The vaginal swabs taken after consensual sex and the evidence collected from rape victims showed a similar pattern of Erase providing superior profiles. CONCLUSIONS: In all samples tested, STR profiles of the male DNA fractions obtained with Erase were as good as or better than those obtained using the standard methods.

Validation of methane measurement using headspace-GC-MS and quantification by a stable isotope-labeled internal standard generated in situ.

A previous study has shown the possibility to identify methane (CH4 ) using headspace-GC-MS and quantify it with a stable isotope as internal standard. The main drawback of the GC-MS methods discussed in literature for CH4 measurement is the absence of a specific internal standard necessary to perform quantification. However, it becomes essential to develop a safer method to limit the manipulation of gaseous CH4 and to precisely control the injected amount of gas for spiking and calibration by comparison with external calibration. To avoid the manipulation of a stable isotope-labeled gas, we have chosen to generate a labeled gas as an internal standard in a vial on the basis of the formation of CH4 by the reaction of Grignard reagent methylmagnesium chloride with deuterated water. This method allows precise measurement of CH4 concentrations in gaseous sample as well as in a solid or a liquid sample after a thermodesorption step in a headspace vial. A full accuracy profile validation of this method is then presented.

IRM cardiaque: imagerie de référence dans le diagnostic de la myocardite aiguë [Cardiac magnetic resonance in acute myocarditis: a new non-invasive diagnostic gold standard?].

Acute myocarditis was until recently one of the most difficult diagnoses in cardiology. The spectrum of signs and symptoms is very wide, the usual non-invasive tests lack specificity and the myocardial biopsy is only performed in a minority of cases to confirm the diagnosis. Due to its unique ability to directly image myocardial necrosis, fibrosis and oedema, cardiac magnetic resonance (CMR) is now considered the primary tool for noninvasive assessment of patients with suspected myocarditis. CMR is also useful for monitoring disease activity under treatment. Myocarditis has been associated with the development of dilated cardiomyopathy; CMR could play a role in the follow-up of such cases to detect the progression toward a dilatative phenotype. Precise mapping of myocardial lesions with cardiac MRI is invaluable to guide myocardial biopsy and increase its diagnostic yield by improving sensitivity.

Plasmacytoid dendritic cells promote immunosuppression in ovarian cancer via ICOS costimulation of Foxp3(+) T-regulatory cells.

Epithelial ovarian cancer (EOC) is the fifth most common cause of cancer death among women. Despite its immunogenicity, effective antitumor responses are limited, due, in part, to the presence of forkhead box protein 3-positive (Foxp3(+)) T regulatory (Treg) cells in the tumor microenvironment. However, the mechanisms that regulate the accumulation and the suppressive function of these Foxp3(+) Treg cells are poorly understood. Here, we found that the majority of Foxp3(+) Treg cells accumulating in the tumor microenvironment of EOCs belong to the subset of Foxp3(+) Treg cells expressing inducible costimulator (ICOS). The expansion and the suppressive function of these cells were strictly dependent on ICOS-L costimulation provided by tumor plasmacytoid dendritic cells (pDC). Accordingly, ICOS(+) Foxp3(+) Treg cells were found to localize in close vicinity of tumor pDCs, and their number directly correlated with the numbers of pDCs in the tumors. Furthermore, pDCs and ICOS(+) Foxp3(+) Treg cells were found to be strong predictors for disease progression in patients with ovarian cancer, with ICOS(+) Treg cell subset being a stronger predictor than total Foxp3(+) Treg cells. These findings suggest an essential role for pDCs and ICOS-L in immunosuppression mediated by ICOS(+) Foxp3(+) Treg cells, leading to tumor progression in ovarian cancer.

Indoleamine 2,3-dioxygenase-expressing mature human monocyte-derived dendritic cells expand potent autologous regulatory T cells.

A comprehensive understanding of the complex, autologous cellular interactions and regulatory mechanisms that occur during normal dendritic cell (DC)-stimulated immune responses is critical to optimizing DC-based immunotherapy. We have found that mature, immunogenic human monocyte-derived DCs (moDCs) up-regulate the immune-inhibitory enzyme, indoleamine 2,3-dioxygenase (IDO). Under stringent autologous culture conditions without exogenous cytokines, mature moDCs expand regulatory T cells (Tregs) by an IDO-dependent mechanism. The priming of resting T cells with autologous, IDO-expressing, mature moDCs results in up to 10-fold expansion of CD4(+)CD25(bright)Foxp3(+)CD127(neg) Tregs. Treg expansion requires moDC contact, CD80/CD86 ligation, and endogenous interleukin-2. Cytofluorographically sorted CD4(+) CD25(bright)Foxp3(+) Tregs inhibit as much as 80% to 90% of DC-stimulated autologous and allogeneic T-cell proliferation, in a dose-dependent manner at Treg:T-cell ratios of 1:1, 1:5, and as low as 1:25. CD4(+)CD25(bright)Foxp3(+) Tregs also suppress the generation of cytotoxic T lymphocytes specific for the Wilms tumor antigen 1, resulting in more than an 80% decrease in specific target cell lysis. Suppression by Tregs is both contact-dependent and transforming growth factor-beta-mediated. Although mature moDCs can generate Tregs by this IDO-dependent mechanism to limit otherwise unrestrained immune responses, inhibition of this counter-regulatory pathway should also prove useful in sustaining responses stimulated by DC-based immunotherapy.
