Immunologic diseases. Allergy ,RC581-607 - Abstract
Therapeutic vaccines based on monocyte-derived dendritic cells have been shown to be promising strategies and may act as complementary treatments for viral infections, cancers, and, more recently, autoimmune diseases. Alpha-type-1-polarized dendritic cells (aDC1s) have been shown to induce type-1 immunity with a high capacity to produce interleukin-12p70 (IL-12p70). In the clinical use of cell-based therapeutics, injectable solutions can affect the morphology, immunophenotypic profile, and viability of cells before delivery and their survival after injection. In this sense, preparing a cell suspension that maintains the quality of aDC1s is essential to ensure effective immunotherapy. In the present study, monocytes were differentiated into aDC1s in the presence of IL-4 and GM-CSF. On day 5, the cells were matured by the addition of a cytokine cocktail consisting of IFN-α, IFN-γ, IL-1β, TNF-α, and Poly I:C. After 48 hr, mature aDC1s were harvested and suspended in two different solutions: normal saline and Ringer’s lactate. The maintenance of cells in suspension was evaluated after 4, 6, and 8 hr of storage. Cell viability, immunophenotyping, and apoptosis analyses were performed by flow cytometry. Cellular morphology was observed by electron microscopy, and the production of IL-12p70 by aDC1s was evaluated by ELISA. Compared with normal saline, Ringer’s lactate solution was more effective at maintaining DC viability for up to 8 hr of incubation at 4 or 22°C.

Abstract We investigated the anti-SARS-CoV-2 post-vaccine response through serum and salivary antibodies, serum antibody neutralizing activity and cellular immune response in samples from health care workers who were immunized with two doses of an inactivated virus-based vaccine (CoronaVac) who had or did not have COVID-19 previously. IgA and IgG antibodies directed at the spike protein were analysed in samples of saliva and/or serum by ELISA and/or chemiluminescence assays; the neutralizing activity of serum antibodies against reference strain B, Gamma and Delta SARS-CoV-2 variants were evaluated using a virus neutralization test and SARS-CoV-2 reactive interferon-gamma T-cell were analysed by flow cytometry. CoronaVac was able to induce serum and salivary IgG anti-spike antibodies and IFN-γ producing T cells in most individuals who had recovered from COVID-19 and/or were vaccinated. Virus neutralizing activity was observed against the ancestral strain, with a reduced response against the variants. Vaccinated individuals who had previous COVID-19 presented higher responses than vaccinated individuals for all variables analysed. Our study provides evidence that the CoronaVac vaccine was able to induce the production of specific serum and saliva antibodies, serum virus neutralizing activity and cellular immune response, which were increased in previously COVID-19-infected individuals compared to uninfected individuals.

IntroductionConsidering the likely need for the development of novel effective vaccines adapted to emerging relevant CoV-2 variants, the increasing knowledge of epitope recognition profile among convalescents and afterwards vaccinated with identification of immunodominant regions may provide important information.MethodsWe used an RBD peptide microarray to identify IgG and IgA binding regions in serum of 71 COVID-19 convalescents and 18 vaccinated individuals. ResultsWe found a set of immunodominant RBD antibody epitopes, each recognized by more than 30% of the tested cohort, that differ among the two different groups and are within conserved regions among betacoronavirus. Of those, only one peptide, P44 (S415-429), recognized by 68% of convalescents, presented IgG and IgA antibody reactivity that positively correlated with nAb titers, suggesting that this is a relevant RBD region and a potential target of IgG/IgA neutralizing activity.DiscussionThis peptide is localized within the area of contact with ACE-2 and harbors the mutation hotspot site K417 present in gamma (K417T), beta (K417N), and omicron (K417N) variants of concern. The epitope profile of vaccinated individuals differed from convalescents, with a more diverse repertoire of immunodominant peptides, recognized by more than 30% of the cohort. Noteworthy, immunodominant regions of recognition by vaccinated coincide with mutation sites at Omicron BA.1, an important variant emerging after massive vaccination. Together, our data show that immune pressure induced by dominant antibody responses may favor hotspot mutation sites and the selection of variants capable of evading humoral response.

Several Prunus species are among the most important cultivated stone fruits in the Mediterranean region, and there is an urgent need to obtain rootstocks with specific adaptations to challenging environmental conditions. The development of adventitious roots (ARs) is an evolutionary mechanism of high relevance for stress tolerance, which has led to the development of environmentally resilient plants. As a first step towards understanding the genetic determinants involved in AR formation in Prunus sp., we evaluated the rooting of hardwood cuttings from five Prunus rootstocks (Adafuel, Adarcias, Cadaman, Garnem, and GF 677) grown in hydroponics. We found that auxin-induced callus and rooting responses were strongly genotype-dependent. To investigate the molecular mechanisms involved in these differential responses, we performed a time-series study of AR formation in two rootstocks with contrasting rooting performance, Garnem and GF 677, by culturing in vitro microcuttings with and without auxin treatment (0.9 mg/L of indole-3-butyric acid [IBA]). Despite showing a similar histological structure, Garnem and GF677 rootstocks displayed dynamic changes in endogenous hormone homeostasis involving metabolites such as indole-3-acetic acid (IAA) conjugated to aspartic acid (IAA-Asp), and these changes could explain the differences observed during rooting.

- Abstract
Prolonged cold stress has a strong effect on plant growth and development, especially in subtropical crops such as maize. Soil temperature limits primary root elongation, mainly during early seedling establishment. However, little is known about how moderate temperature fluctuations affect root growth at the molecular and physiological levels. We have studied root tips of young maize seedlings grown hydroponically at 30 ºC and after a short period (up to 24 h) of moderate cooling (20 ºC). We found that both cell division and cell elongation in the root apical meristem are affected by temperature. Time-course analyses of hormonal and transcriptomic profiles were achieved after temperature reduction from 30 ºC to 20 ºC. Our results highlighted a complex regulation of endogenous pathways leading to adaptive root responses to moderate cooling conditions

Root systems can display variable architectures that contribute to nutrient foraging or to increase the tolerance of abiotic stress conditions. Root tip excision promotes the developmental progression of previously specified lateral root (LR) founder cells, which allows to easily measuring the branching capacity of a given root as regards its genotype and/or growth conditions. Here, we describe the natural variation among 120 Arabidopsis thaliana accessions in root system architecture (RSA) after root tip excision. Wound-induced changes in RSA were associated with 19 genomic loci using genome-wide association mapping. Three candidate loci associated with wound-induced LR formation were investigated. Sequence variation in the hypothetical protein encoded by the At4g01090 gene affected wound-induced LR development and its loss-of-function mutants displayed a reduced number of LRs after root tip excision. Changes in a histidine phosphotransfer protein putatively involved in cytokinin signaling were significantly associated with LR number variation after root tip excision. Our results provide a better understanding of some of the genetic components involved in LR capacity variation among accessions.

EOSC ,KT ,Citizen Sciece ,Knowledge Transfer - Abstract
This Knowledge Transfer Report describes and evaluate Knowledge Transfer activities undertaken by the Cos4Cloud project. Cos4Cloud's methodology to develop and monitor its KT strategy was based on common practices implemented by the H2020 community and on requirements and recommendations from the funding agency, the European Commission. It is important to underline that some aspects of a KT strategy cannot be evaluated quantitatively and have been challenging to measure. Having said that, the Cos4Cloud methodology for KT transfer and its evaluation has proven itself effective for keeping track of the consortium efforts in KT, monitoring the Cos4Cloud KT activities and whether they were aligned with the target stakeholders and the KT goals, as well as to adjust the strategy if necessary. Implementing and evaluating the Cos4Cloud Knowledge Transfer framework has been a unique opportunity to understand KT within the project, providing us with some practical lessons to make this transfer effective. In the case of Cos4Cloud, setting up clear KT Outputs and key stakeholders was crucial for developing the project’s KT strategy and involving all the consortium members in its implementation. Besides, in Cos4Cloud, the events were key for the success of the KT strategy; they allowed us to be in direct contact with the community and make this transfer more effective.

Commercial carnation (Dianthus caryophyllus) cultivars are vegetatively propagated from axillary stem cuttings through adventitious rooting; a process which is affected by complex interactions between nutrient and hormone levels and is strongly genotype-dependent. To deepen our understanding of the regulatory events controlling this process, we performed a comparative study of adventitious root (AR) formation in two carnation cultivars with contrasting rooting performance, “2101–02 MFR” and “2003 R 8”, as well as in the reference cultivar “Master”. We provided molecular evidence that localized auxin response in the stem cutting base was required for efficient adventitious rooting in this species, which was dynamically established by polar auxin transport from the leaves. In turn, the bad-rooting behavior of the “2003 R 8” cultivar was correlated with enhanced synthesis of indole-3-acetic acid conjugated to aspartic acid by GH3 proteins in the stem cutting base. Treatment of stem cuttings with a competitive inhibitor of GH3 enzyme activity significantly improved rooting of “2003 R 8”. Our results allowed us to propose a working model where endogenous auxin homeostasis regulated by GH3 proteins accounts for the cultivar dependency of AR formation in carnation stem cuttings.

This guide results from the experience and lessons learned in co-designing thirteen technologicalservices within the Cos4Cloud project. The technological services were created from a bottom-up approach, following a co-design process connected to an agile software development methodology. The co-design team implemented the co-design process as a service within the Cos4Cloud consortium, as stated in task 5.2. The result of implementing the co-design framework and methodologies and the corresponding monitoring during the co-design of the services, were evaluated and adapted to be shared with the citizen science community as a methodological guide. The present methodological guide includes an introduction to the world of co-design, where the main definitions and mindsets of co-design and design thinking are given, as well as some tools to start applying the creative methodologies within them. Secondly, it introduces the co-design methodology followed in Cos4Cloud, together with some important concepts, such as citizen science and citizen observatories. Then, a practical guide of implementation is given, including all the co-design methodologies used in Cos4Cloud. The most standard methods include a description and a work map template, while the customised ones incorporate a step-by-step guide to implement them. Finally, an explanation is given on how the co-design process was implemented in Cos4Cloud as a service for software developers, by using three interactive platforms that allowed us to perform all creative sessions. The document concludes with an invitation to implement co-design processes in other software development projects.

Soil temperature limits primary root elongation, mainly during early seedling establishment. However, little is known about how moderate temperature fluctuations affect root growth at the molecular and physiological levels. We have studied root tips of young maize seedlings grown hydroponically at 30 ºC and after a short period (up to 24 h) of moderate cooling (20 ºC). We found that both cell division and cell elongation in the root apical meristem are affected by temperature. Time-course analyses of hormonal and transcriptomic profiles were achieved after temperature reduction from 30 ºC to 20 ºC. Our results highlighted a complex regulation of endogenous pathways leading to adaptive root responses to moderate cooling conditions.

The rooting of stem cuttings is a highly efficient procedure for the vegetative propagation of ornamental plants. In cultivated carnations, an increased auxin level in the stem cutting base produced by active auxin transport from the leaves triggers adventitious root (AR) formation from the cambium. To provide additional insight into the physiological and genetic basis of this complex trait, we studied AR formation in a collection of 159 F1 lines derived from a cross between two hybrid cultivars (2003 R 8 and 2101-02 MFR) showing contrasting rooting performances. In three different experiments, time-series for several stem and root architectural traits were quantified in detail in a subset of these double-cross hybrid lines displaying extreme rooting phenotypes and their parental genotypes. Our results indicate that the water content and area of the AR system directly contributed to the shoot water content and shoot growth. Moreover, morphometric data and rooting quality parameters were found to be associated with some stress-related metabolites such as 1-aminocyclopropane-1-carboxylic acid (ACC), the ethylene precursor, and the conjugated auxin indol-3-acetic acid-aspartic acid (IAA-Asp).

- Abstract
Several Prunus species are among the most important cultivated stone fruits in the Mediterranean region, and there is an urgent need to obtain rootstocks with specific adaptations to challenging environmental conditions. The development of adventitious roots (ARs) is an evolutionary mechanism of high relevance for stress tolerance, which has led to the development of environmentally resilient plants. As a first step towards understanding the genetic determinants involved in AR formation in Prunus sp., we evaluated the rooting of hardwood cuttings from five Prunus rootstocks (Adafuel, Adarcias, Cadaman, Garnem, and GF 677) grown in hydroponics. We found that auxin-induced callus and rooting responses were strongly genotype-dependent. To investigate the molecular mechanisms involved in these differential responses, we performed a time-series study of AR formation in two rootstocks with contrasting rooting performance, Garnem and GF 677, by culturing in vitro microcuttings with and without auxin treatment (0.9 mg/L of indole-3-butyric acid [IBA]). Despite showing a similar histological structure, Garnem and GF677 rootstocks displayed dynamic changes in endogenous hormone homeostasis involving metabolites such as indole-3-acetic acid (IAA) conjugated to aspartic acid (IAA-Asp), and these changes could explain the differences observed during rooting.

- Abstract
PurposeCentral venous catheters (CVCs) have become common practice in oncology. Besides their benefits, as an invasive procedure, several complications are associated with them. Catheter associated thrombosis (CAT) is one of the most relevant due to their impact in quality of life and mortality, but the prothrombotic risk factors implied have been poorly assessed. The aim of the study is to evaluate the incidence of upper extremity deep vein thrombosis (UEDVT) associated to catheter use in patients with solid tumors. Secondary endpoints are to describe the population using CVCs and to evaluate potential risk factors of CAT. MethodsPatients diagnosed of solid tumors assisted at a tertiary level hospital between 2016 and 2019, and using CVCs were included.Results455 patients were enrolled. The incidence of CAT was 5.49% (25) in the whole population. 5.05% (23) was associated with PICC while 0.44% (2) was due to PORT use. Among the factors included in the univariate and multivariate regression models, age ≥50 years and PORT use were identified as protective factors related to the development of CAT.ConclusionCVCs remains a safe approach for the delivering of treatments in patients with solid tumors. Age ≤50 and use of PICC are risk factors for developing CAT. Larger prospective studies are needed to identify additional risk factors of CAT.

- Abstract
These are the slides from the LIBER 2021 Workshop: Onboarding Citizen Science and the role of research libraries barriers and accelerators This workshop derives from the SSHOC - Social Sciences and Humanities Open Cloud work in collaboration with the LIBER Citizen Science working group. It will be building on the outcomes of the session“ Citizen Science: What it means for SSH and how can multidisciplinarity be achieved?” that took place during the conference “Realising the European Open Science Cloud: Towards a FAIR research data landscape for the social sciences, humanities and beyond.” in November 2020. Objective The overarching aim of this workshop is to raise the awareness of the challenges and opportunities in libraries’ involvement with Citizen Science in SSH. It aims to explore the extent to which research libraries can serve as a bridge between researchers and citizens. An approach based on the sharing of best practices and current research, the involvement of participants in the reflection of the respective roles and training needed, complemented by an open discussion, will shape the overall experience. One of the outputs of this workshop will be the production of actionable recommendations for research libraries and the SSHOC/SSH communities in the form of a report. This will be complemented by a proposed outline of potential awareness raising and training sessions (for librarians, researchers, and citizen scientists) that would help participants in implementing those recommendations. This workshop will be an opportunity to create further synergies between LIBER, SSHOC and initiatives represented by the speakers and the participants.

Trasplante de órganos ,6 - Ciencias aplicadas::61 - Medicina [CDU] ,Gitanos - Abstract
Introducción: El trasplante de órganos es, en casos de lesión irreversible de algún órgano y pérdida irrecuperable de su función, la única alternativa para poder recuperar la salud. Sin embargo, el principal factor limitante a esta terapia es la escasez de órganos. Para disminuir las negativas familiares a la donación de órganos, fuertemente influenciadas por diferentes factores psicosociales, debemos investigar sobre la actitud y el conocimiento de las variables que influyen en la donación, especialmente en grupos sociales con actitud más negativa, como la etnia gitana. El objetivo de esta tesis es conocer la actitud hacia la donación de órganos propios para el trasplante tras el fallecimiento entre la población gitana española mayor o igual a 15 años y analizar las variables psicosociales que condicionan dicha actitud. Material y método: Estudio observacional, transversal, de ámbito nacional, español en población gitana con edad igual o mayor de 15 años, estratificada por edad y género. Se estimó un tamaño muestral de 1253. Como instrumento de medida se emplea un cuestionario validado de actitud hacia la donación (“PCID–DTO Ríos”: Cuestionario del Proyecto Colaborativo Internacional Donante). Para el análisis estadístico se utilizó el test de Student, el test de chi-cuadrado y un análisis de regresión logística. Resultados: El cuestionario fue cumplimentado por 228 de 1253 encuestados, que implica un 18,2% de grado de cumplimentación y 81,8% de pérdidas. Se objetiva que la opinión hacia la donación de órganos propios tras el fallecimiento es favorable en 42,1% (n=96), estando el 27,6% (n=63) en contra y el 30,3% de indecisos (n=69). Debido a la baja cumplimentación, uno de los objetivos planteados era conocer las razones de dicha negativa. El 97,9% de los que no cumplimentan, argumentan miedo a hablar del tema de la muerte y la donación y si consideramos que éstos no presentan una actitud favorable hacia la donación de órganos propios, los resultados serían los siguientes: El 7,7% (n=96) presentan una actitud favorable, frente al 90,7% (n=1136) que presentan una actitud no favorable. Edad media 35,4 ± 14,4 años. Las siguientes variables se asociaron con la actitud hacia la donación: edad (p=0.029), género (p=0,018), nivel de estudios del encuestado (p

The adventitious root formation is critical for the plant survival during its vegetative propagation through cuttings, hence the study and understanding of this process is strategic during mass propagation of the new elite varieties obtained by genetic breeding. This Thesis pursues genetic, morphological and hormonal studies of de novo root formation in the Arabidopsis thaliana (L.) Heynh. model, and in two other plant species of agronomic interest in the Mediterranean region, such as the cultivated carnation (Dianthus caryophyllus L.) and the argan tree (Argania spinosa [L.] Skeels). To identify some genetic determinants involved in woundinduced root formation process, we carried out a genomewide association (GWA) study in a collection of 174 Arabidopsis thaliana natural accessions. We found statistically significant associations between woundinduced root system architectural traits and 19 genomic loci. We then studied three candidate loci associated with woundinduced lateral root formation. Lossoffunction mutants in one of these genes, At4g01090, which encodes a protein of unknown function, were affected in woundinduced lateral root development. We identified null alleles in the At5g19710 gene, which encodes a histidine phosphotransfer protein putatively involved in cytokinin signalling, with a reduced number of lateral roots after root tip excision. In addition, we found an epistatic interaction between several nonsynonymous single nucleotide polymorphisms in the coding region of K+ UPTAKE TRANSPORTER 5 (KUP5), which encodes a potassium uptake transporter; and At5g19710, which would point to a functional relationship between both processes and woundinduced root formation. We studied morphological changes occurring in the basal region of stem cuttings during rooting in a collection of 159 F1 lines derived from a cross between two carnation hybrid cultivars, 210102 MFR and 2003 R 8, with contrasting rooting performances. We provided molecular evidence that the badrooting behaviour of 2003 R 8 cuttings was caused by an early inactivation of active auxin, indole3acetic acid, through its conjugation with aspartic acid by GRETCHEN HAGEN 3 proteins. Our analyses further elucidated the relationship between the physiological state of carnation cuttings, estimated by the proportion of salicylic acid and jasmonate, and the formation of adventitious roots. In addition, we developed an effective method for argan micropropagation from in vitro germinated seeds and we considerably increased the adventitious rooting from lignified cuttings obtained from adult plants. When combined with a suitable genetic selection, our procedure will allow the efficient production of elite varieties of argan trees for intensive cultivation. La formación de raíces adventicias supone un paso crítico y de vital importancia para la supervivencia de las plantas que se propagan vegetativamente mediante esquejes, por lo que el estudio y la comprensión de este proceso es clave para optimizar la propagación vegetativa de las nuevas variedades élite obtenidas por métodos convencionales de mejora genética. En esta Tesis se propone el estudio a nivel genético, morfológico y hormonal de la formación de raíces de novo en la crucífera modelo Arabidopsis thaliana (L.) Heynh., y en dos especies de interés agronómico en la región mediterránea: el clavel cultivado (Dianthus caryophyllus L.) y el argán (Argania spinosa [L.] Skeels). Para identificar algunos de los determinantes genéticos implicados en la formación de raíces en respuesta a herida, hemos llevado a cabo un estudio de asociación a genoma completo o GWA (genomewide association study) en una colección de 174 estirpes silvestres de Arabidopsis thaliana. Nuestros resultados indican que existen asociaciones estadísticamente significativas entre los cambios en la arquitectura radicular en respuesta a herida y 19 regiones genómicas concretas. Nos hemos centrado en el análisis genético de 6 polimorfismos de un solo nucleótido o SNPs (single nucleotide polymorphisms) que generan cambios no conservados de residuos aminoacídicos en la región codificante de tres genes. Los mutantes de pérdida de función en At4g01090, que codifica una proteína de función desconocida, muestran un menor número de raíces laterales en respuesta a herida. Hemos identificado alelos nulos en el gen At5g19710, que codifica una proteína con un dominio de histidina para la fosfotransferencia implicado en la señalización de las citoquininas, con un número reducido de raíces laterales en respuesta a herida. Además, hemos encontrado una interacción epistática entre los SNPs de la región codificante de K+ UPTAKE TRANSPORTER 5 (KUP5), cuyo producto participa en la asimilación del potasio, y At5g19710, lo que apuntaría a una relación funcional entre ambos procesos y con la formación de raíces en respuesta a herida. Por otra parte, hemos llevado a cabo un análisis detallado de la formación de raíces adventicias a partir de esquejes de clavel cultivado en una colección de 159 líneas F1 derivadas del cruzamiento entre dos variedades comerciales, 210102 MFR y 2003 R 8, que difieren de forma significativa en su capacidad de enraizamiento adventicio. Hemos proporcionado evidencias moleculares de que la baja capacidad de enraizamiento adventicio de los esquejes en la estirpe 2003 R 8 se debe a una inactivación temprana de la auxina activa, el ácido indolacético, en la base del esqueje mediante su conjugación con ácido aspártico por enzimas de la familia GRETCHEN HAGEN 3. Nuestros análisis han permitido dilucidar, además, la relación existente entre el estado fisiológico de los esquejes de clavel, estimada por la proporción de ácidos salicílico y jasmónico, y la formación de raíces adventicias. Adicionalmente, hemos desarrollado un método eficaz para la micropropagación del argán a partir de semillas germinadas in vitro, además de un protocolo que ha permitido incrementar considerablemente la formación de raíces adventicias a partir de esquejes lignificados obtenidos de plantas adultas. Combinado con una selección genética adecuada, nuestro procedimiento permitirá la producción eficiente de variedades élite de argán para su uso en cultivo intensivo.

Plants have a remarkable regenerative capacity, which allows them to survive tissue damage after biotic and abiotic stresses. In this study, we use Solanum lycopersicum ‘Micro-Tom’ explants as a model to investigate wound-induced de novo organ formation, as these explants can regenerate the missing structures without the exogenous application of plant hormones. Here, we performed simultaneous targeted profiling of 22 phytohormone-related metabolites during de novo organ formation and found that endogenous hormone levels dynamically changed after root and shoot excision, according to region-specific patterns. Our results indicate that a defined temporal window of high auxin-to-cytokinin accumulation in the basal region of the explants was required for adventitious root formation and that was dependent on a concerted regulation of polar auxin transport through the hypocotyl, of local induction of auxin biosynthesis, and of local inhibition of auxin degradation. In the apical region, though, a minimum of auxin-to-cytokinin ratio is established shortly after wounding both by decreasing active auxin levels and by draining auxin via its basipetal transport and internalization. Cross-validation with transcriptomic data highlighted the main hormonal gradients involved in wound-induced de novo organ formation in tomato hypocotyl explants.
