Role of Moonlighting Proteins in Disease : Analyzing the Contribution of Canonical and Moonlighting Functions in Disease Progression

The term moonlighting proteins refers to those proteins that present alternative functions performed by a single polypeptide chain acquired throughout evolution (called canonical and moonlighting, respectively). Over 78% of moonlighting proteins are involved in human diseases, 48% are targeted by current drugs, and over 25% of them are involved in the virulence of pathogenic microorganisms. These facts encouraged us to study the link between the functions of moonlighting proteins and disease. We found a large number of moonlighting functions activated by pathological conditions that are highly involved in disease development and progression. The factors that activate some moonlighting functions take place only in pathological conditions, such as specific cellular translocations or changes in protein structure. Some moonlighting functions are involved in disease promotion while others are involved in curbing it. The disease-impairing moonlighting functions attempt to restore the homeostasis, or to reduce the damage linked to the imbalance caused by the disease. The disease-promoting moonlighting functions primarily involve the immune system, mesenchyme cross-talk, or excessive tissue proliferation. We often find moonlighting functions linked to the canonical function in a pathological context. Moonlighting functions are especially coordinated in inflammation and cancer. Wound healing and epithelial to mesenchymal transition are very representative. They involve multiple moonlighting proteins with a different role in each phase of the process, contributing to the current-phase phenotype or promoting a phase switch, mitigating the damage or intensifying the remodeling. All of this implies a new level of complexity in the study of pathology genesis, progression, and treatment. The specific protein function involved in a patient's progress or that is affected by a drug must be elucidated for the correct treatment of diseases

A hypothesis explaining why so many pathogen virulence proteins are moonlighting proteins

Moonlighting or multitasking proteins refer to those proteins with two or more functions performed by a single polypeptide chain. Proteins that belong to key ancestral functions and metabolic pathways such as primary metabolism typically exhibit moonlighting phenomenon. We have collected 698 moonlighting proteins in MultitaskProtDB-II database. A survey shows that 25% of the proteins of the database correspond to moonlighting functions related to pathogens virulence activity. Why is the canonical function of these virulence proteins mainly from ancestral key biological functions (especially of primary metabolism)? Our hypothesis is that these proteins present a high conservation between the pathogen protein and the host counterparts. Therefore, the host immune system will not elicit protective antibodies against pathogen proteins. The fact of sharing epitopes with host proteins (known as epitope mimicry) might be the cause of autoimmune diseases. Although many pathogen proteins can be antigenic, only a few of them would elicit a protective immune response. This would also explain the lack of successful vaccines based in these conserved moonlighting proteins. This review looks at why so many pathogen virulence proteins are from the primary metabolism and are conserved between pathogen and host

MultitaskProtDB-II : an update of a database of multitasking/moonlighting proteins

Multitasking, or moonlighting, is the capability of some proteins to execute two or more biological functions. MultitaskProtDB-II is a database of multifunctional proteins that has been updated. In the previous version, the information contained was: NCBI and UniProt accession numbers, canonical and additional biological functions, organism, monomeric/oligomeric states, PDB codes and bibliographic references. In the present update, the number of entries has been increased from 288 to 694 moonlighting proteins. MultitaskProtDB-II is continually being curated and updated. The new database also contains the following information: GO descriptors for the canonical and moonlighting functions, three-dimensional structure (for those proteins lacking PDB structure, a model was made using Itasser and Phyre), the involvement of the proteins in human diseases (78% of human moonlighting proteins) and whether the protein is a target of a current drug (48% of human moonlighting proteins). These numbers highlight the importance of these proteins for the analysis and explanation of human diseases and target-directed drug design. Moreover, 25% of the proteins of the database are involved in virulence of pathogenic microorganisms, largely in the mechanism of adhesion to the host. This highlights their importance for the mechanism of microorganism infection and vaccine design. MultitaskProtDB-II is available at http://wallace.uab.es/multitaskII

Study protocol for the multicentre cohorts of Zika virus infection in pregnant women, infants, and acute clinical cases in Latin America and the Caribbean: The ZIKAlliance consortium

Background: The European Commission (EC) Horizon 2020 (H2020)-funded ZIKAlliance Consortium designed a multicentre study including pregnant women (PW), children (CH) and natural history (NH) cohorts. Clinical sites were selected over a wide geographic range within Latin America and the Caribbean, taking into account the dynamic course of the ZIKV epidemic. Methods: Recruitment to the PW cohort will take place in antenatal care clinics. PW will be enrolled regardless of symptoms and followed over the course of pregnancy, approximately every 4 weeks. PW will be revisited at delivery (or after miscarriage/abortion) to assess birth outcomes, including microcephaly and other congenital abnormalities according to the evolving definition of congenital Zika syndrome (CZS). After birth, children will be followed for 2 years in the CH cohort. Follow-up visits are scheduled at ages 1-3, 4-6, 12, and 24 months to assess neurocognitive and developmental milestones. In addition, a NH cohort for the characterization of symptomatic rash/fever illness was designed, including follow-up to capture persisting health problems. Blood, urine, and other biological materials will be collected, and tested for ZIKV and other relevant arboviral diseases (dengue, chikungunya, yellow fever) using RT-PCR or serological methods. A virtual, decentralized biobank will be created. Reciprocal clinical monitoring has been established between partner sites. Substudies of ZIKV seroprevalence, transmissio

Nuevos modelos de atención sanitaria para las personas transgénero en el sistema sanitario español: Demandas, controversias y reflexiones

Health care for transgender people in Spain has been progressively established since 1999 when the first multidisciplinary unit for the treatment of sex reassignment was created in Andalusia. In this document, the social changes, the demands and debates of users and professionals, the new models of health care for trans people, and reflections on the current situation, have been analysed. The social openness in Spain regarding sexual and gender diversity has evolved quite positively. The health demands of the transgender users are not uniform and do not always match with the criteria of the professionals. In some Spanish regions, health care is distancing itself from the internationally recommended multidisciplinary model. The new healthcare models have been established under the aegis of primary care and/or endocrinologist in the area, without a required psychological assessment. The main contributing factors for this change of model have been the pressure from some associations with demands for “depathologization” and “decentralization”. The professionals of gender units, while recognizing the need for a broader vision of trans reality, warn of the risk of treating trans people without the involvement of mental health specialists or by professionals in proximity with little experience. Moreover, the decentralization would not allow acting on large cohorts, which hinders the advance of knowledge and contrasted evaluations with neighbouring countries. In summary, the new health models, although intended to facilitate care through proximity, do not guarantee improvements in quality and difficult to make a comparative evaluation of the results.La atención sanitaria a las personas transgénero en España se ha establecido de manera progresiva desde 1999, año en que Andalucía crea la primera unidad multidisciplinar para el tratamiento integral de la reasignación de sexo. Este documento analiza los cambios sociales, las demandas y debates entre usuarios y profesionales y los nuevos modelos de atención sanitaria, y también plantea reflexiones sobre la situación actual. La apertura social en España en la concepción de la diversidad sexual y de género es bastante favorable. Las demandas de los usuarios no son uniformes y no siempre coinciden con los criterios de los profesionales. En algunas comunidades autónomas la asistencia sanitaria se está distanciando del modelo recomendado internacionalmente, que basa la atención en equipos especializados o Unidades de Identidad de Género (UIG). Estos nuevos modelos centran la asistencia en la Atención Primaria, además de en endocrinólogos y pediatras de área sin una evaluación coordinada con Salud Mental. Los principales factores contribuyentes al cambio reciente han sido las demandas desde algunas asociaciones de “despatologización” y “descentralización”. Los profesionales que integran las unidades de género, si bien reconocen la necesidad de una visión amplia de la realidad transgénero, alertan del riesgo que supone tratar a personas trans sin una colaboración de especialistas en Salud Mental o por profesionales de área con escasa experiencia. Además, anticipan que la descentralización no facilita el estudio de grandes cohortes, dificultando el avance del conocimiento y la evaluación contrastada con países del entorno. En resumen, los nuevos modelos sanitarios, aunque ofrecen la atención en proximidad, no garantizan mejoras en la calidad ni promueven el análisis comparado de los resultados

EndoMapper dataset of complete calibrated endoscopy procedures

Computer-assisted systems are becoming broadly used in medicine. In endoscopy, most research focuses on automatic detection of polyps or other pathologies, but localization and navigation of the endoscope is completely performed manually by physicians. To broaden this research and bring spatial Artificial Intelligence to endoscopies, data from complete procedures are needed. This data will be used to build a 3D mapping and localization systems that can perform special task like, for example, detect blind zones during exploration, provide automatic polyp measurements, guide doctors to a polyp found in a previous exploration and retrieve previous images of the same area aligning them for easy comparison. These systems will provide an improvement in the quality and precision of the procedures while lowering the burden on the physicians. This paper introduces the Endomapper dataset, the first collection of complete endoscopy sequences acquired during regular medical practice, including slow and careful screening explorations, making secondary use of medical data. Its original purpose is to facilitate the development and evaluation of VSLAM (Visual Simultaneous Localization and Mapping) methods in real endoscopy data. The first release of the dataset is composed of 59 sequences with more than 15 hours of video. It is also the first endoscopic dataset that includes both the computed geometric and photometric endoscope calibration with the original calibration videos. Meta-data and annotations associated to the dataset varies from anatomical landmark and description of the procedure labeling, tools segmentation masks, COLMAP 3D reconstructions, simulated sequences with groundtruth and meta-data related to special cases, such as sequences from the same patient. This information will improve the research in endoscopic VSLAM, as well as other research lines, and create new research lines.Comment: 11 pages, 7 figures, 4 table
