Implementación de un sistema de escenarios futuros sobre el mapa de usos de suelo de Andalucía.

La Consejería de Medio Ambiente (CMA) ha puesto en marcha un estudio para la generación de cartografía prospectiva de usos de suelo en la Andalucía del siglo XXI. El objeto de este proyecto es explorar y analizar la posible evolución a medio-largo plazo de los usos del suelo y sus implicaciones ambientales, en un contexto de cambio global según diferentes escenarios. Los estudios prospectivos tales como, la construcción de escenarios, permiten iluminar la toma de decisiones. La distribución de los usos de suelo influye en el crecimiento y desarrollo de nuestra sociedad y representa un elemento importante para predecir los impactos ambientales. Actualmente la CMA dispone de una cartografía con los más elevados niveles de detalle y precisión espacial, que cumple los estándares cartográficos internacionales, y que cubre los últimos 50 años en la evolución de los usos del suelo en nuestra región. El poder anticipar, bajo diferentes supuestos de desarrollo socioeconómico, la evolución y la distribución de los usos del suelo en el futuro, supondría avanzar y complementar esta línea de trabajo. La integración de estos factores se ha llevado a cabo mediante autómatas celulares utilizados para modelar los cambios de uso y el desarrollo urbano.The Environmental Ministry of the Andalusian Regional Government has initiated a study to generate prospective mapping of land uses in Andalusia in the XXI century. The goal of this project is to explore and analyze medium to long- term land uses changes and their environmental implications according to different scenarios in the context of global change. Predicting land use change under such scenarios will provide valuable information to decision makers. The distribution of the land uses influences in the growth and development of our society and thus represents a crucial element to predict future environmental impacts. The Environmental Ministry of Andalusia currently has maps available that depict land use changes in the region over the past 50 years and contain the highest level of detail and spatial precision according to international cartographic standards. The power to predict the growth and distribution of future land uses under different assumptions of socioeconomic development will advance and complement this work. The integration of these factors is carried out based on cellular automata applied to model land use changes and urban development

Searching for the Transcriptomic Signature of Immune Tolerance Induction—Biomarkers of Safety and Functionality for Tolerogenic Dendritic Cells and Regulatory Macrophages

The last years have witnessed a breakthrough in the development of cell-based tolerance-inducing cell therapies for the treatment of autoimmune diseases and solid-organ transplantation. Indeed, the use of tolerogenic dendritic cells (tolDC) and regulatory macrophages (Mreg) is currently being tested in Phase I and Phase II clinical trials worldwide, with the aim of finding an effective therapy able to abrogate the inflammatory processes causing these pathologies without compromising the protective immunity of the patients. However, there exists a wide variety of different protocols to generate human tolDC and Mreg and, consequently, the characteristics of each product are heterogeneous. For this reason, the identification of biomarkers able to define their functionality (tolerogenicity) is of great relevance, on the one hand, to guarantee the safety of tolDC and Mreg before administration and, on the other hand, to compare the results between different cell products and laboratories. In this article, we perform an exhaustive review of protocols generating human tolDC and Mreg in the literature, aiming to elucidate if there are any common transcriptomic signature or potential biomarkers of tolerogenicity among the different approaches. However, and although several effectors seem to be induced in common in some of the most reported protocols to generate both tolDC or Mreg, the transcriptomic profile of these cellular products strongly varies depending on the approach used to generate them

Vitamin D3-Induced Tolerogenic Dendritic Cells Modulate the Transcriptomic Profile of T CD4 + Cells Towards a Functional Hyporesponsiveness

The use of autologous tolerogenic dendritic cells (tolDC) has become a promising alternative for the treatment of autoimmune diseases. Among the different strategies available, the use of vitamin D3 for the generation of tolDC (vitD3-tolDC) constitutes one of the most robust approaches due to their immune regulatory properties, which are currently being tested in clinical trials. However, the mechanisms that vitD3-tolDC trigger for the induction of tolerance remain elusive. For this reason, we performed a full phenotypical, functional, and transcriptomic characterization of T cells upon their interaction with autologous, antigen-specific vitD3-tolDC. We observed a strong antigen-specific reduction of T cell proliferation, combined with a decrease in the relative prevalence of T1 subpopulations and IFN- γ production. The analysis of the transcriptomic profile of T CD4 + cells evidenced a significant down-modulation of genes involved in cell cycle and cell response to mainly pro-inflammatory immune-related stimuli, highlighting the role of JUNB gene as a potential biomarker of these processes. Consequently, our results show the induction of a strong antigen-specific hyporesponsiveness combined with a reduction on the T1 immune profile of T cells upon their interaction with vitD3-tolDC, which manifests the regulatory properties of these cells and, therefore, their therapeutic potential in the clinic. https://doi.org/10.13039/5011000033295https://doi.org/10.13039/5011000033293https://doi.org/10.13039/5011000033296https://doi.org/10.13039/501100003329 https://doi.org/10.13039/501100003329_https://doi.org/10.13039/501100003329_https://doi.org/10.13039/501100003329 https://doi.org/10.13039/50110000332

Ethyl Pyruvate Induces Tolerogenic Dendritic Cells

Altres ajuts: Cost Action BM1305Dendritic cells (DC) are professional antigen presenting cells that have a key role in shaping the immune response. Tolerogenic DC (tolDC) have immuno-regulatory properties and they are a promising prospective therapy for multiple sclerosis and other autoimmune diseases. Ethyl pyruvate (EP) is a redox analog of dimethyl fumarate (Tecfidera), a drug for multiple sclerosis treatment. We have recently shown that EP ameliorates experimental autoimmune encephalomyelitis, a multiple sclerosis murine model. Here, we expanded our study to its tolerogenic effects on DC. Phenotypic analysis has shown that DC obtained from mice or humans reduce expression of molecules required for T cell activation such as CD86, CD83, and HLA-DR under the influence of EP, while CD11c expression and viability of DC are not affected. Furthermore, EP-treated DC restrain proliferation and modulate cytokine production of allogeneic lymphocytes. These results demonstrate that EP has the ability to direct DC toward tolDC

Identification of polymorphic inversions from genotypes

Background: Polymorphic inversions are a source of genetic variability with a direct impact on recombination frequencies. Given the difficulty of their experimental study, computational methods have been developed to infer their existence in a large number of individuals using genome-wide data of nucleotide variation. Methods based on haplotype tagging of known inversions attempt to classify individuals as having a normal or inverted allele. Other methods that measure differences between linkage disequilibrium attempt to identify regions with inversions but unable to classify subjects accurately, an essential requirement for association studies. Results: We present a novel method to both identify polymorphic inversions from genome-wide genotype data and classify individuals as containing a normal or inverted allele. Our method, a generalization of a published method for haplotype data [1], utilizes linkage between groups of SNPs to partition a set of individuals into normal and inverted subpopulations. We employ a sliding window scan to identify regions likely to have an inversion, and accumulation of evidence from neighboring SNPs is used to accurately determine the inversion status of each subject. Further, our approach detects inversions directly from genotype data, thus increasing its usability to current genome-wide association studies (GWAS). Conclusions: We demonstrate the accuracy of our method to detect inversions and classify individuals on principled-simulated genotypes, produced by the evolution of an inversion event within a coalescent model [2]. We applied our method to real genotype data from HapMap Phase III to characterize the inversion status of two known inversions within the regions 17q21 and 8p23 across 1184 individuals. Finally, we scan the full genomes of the European Origin (CEU) and Yoruba (YRI) HapMap samples. We find population-based evidence for 9 out of 15 well-established autosomic inversions, and for 52 regions previously predicted by independent experimental methods in ten (9+1) individuals [3,4]. We provide efficient implementations of both genotype and haplotype methods as a unified R package inveRsion

Soft tissue non-Hodgkin lymphoma of shoulder in a HIV patient: a report of a case and review of the literature

The risk of developing lymphoma is greatly increased in HIV infection. Musculoskeletal manifestations of the human immunodeficiency virus (HIV) are common and are sometimes the initial presentation of the disease. Muscle, bone, and joints are involved by septic arthritis, myopathies and neoplasms. HIV-related neoplastic processes that affect the musculoskeletal system include Kaposi's sarcoma and non-Hodgkin's lymphoma, the latter being mainly localized at lower extremities, spine and skull
