En ese sentido los receptores cannabinoides CB1 y CB2 resultan una alternativa para ser utilizados como nuevos blancos terapéuticos. Dado que no se encontró evidencia en la literatura de su presencia en la pulpa dental y en odontoblastos en condiciones de inflamación, este trabajo de tesis tuvo como objetivo evaluar su expresión y funcionalidad en esas condiciones. Este trabajo está dividido en 4 capítulos: en el Capítulo 1 se realizó una revisión bibliográfica en la que se exploró la fisiología de los cannabinoides y de ambos receptores. Dado que no se encontró evidencia de la validación de genes de referencia en odontoblastos humanos en contexto inflamatorio, en el Capítulo 2 se describió una estrategia metodológica para la elección de los genes de referencia más adecuados para la realización de la cuantificación relativa de los receptores cannabinoides por medio de RT-qPCR. En el siguiente Capítulo, se comparó la presencia y actividad de receptores cannabinoides en odontoblastos humanos y en fibroblastos gingivales ya que ambas células tienen un papel importante en la modulación de la inflamación y el dolor en pulpitis y periodontitis. Finalmente, en el Capítulo 4 se evalúa la presencia de CB1 y CB2 en pulpas dentales y la presencia y actividad en cultivo de odontoblastos humanos en condiciones de inflamación. Esto permitió aportar luces sobre el papel de los receptores cannabinoides en el dolor e inflamación en odontología, y además de comprobar su expresión y modulación en células y tejidos dentales, abriendo paso a nuevas investigaciones que usen agonistas de ambos receptores para el control del dolor y la inflamación en encía y pulpa dental. (Texto tomado de la fuente)Inflammation, sensitivity and dental pain continue to be a challenge in dental practice, which is why the search for pharmacological alternatives for their control is a necessity. In this sense, CB1 and CB2 cannabinoid receptors are an alternative to be used as new therapeutic targets. Since no evidence was found in the literature of their presence in dental pulp and odontoblasts under inflammatory conditions, the aim of this thesis was to evaluate their expression and functionality under these conditions. This work is divided into 4 chapters: in Chapter 1, a literature review was conducted in which the physiology of cannabinoids and both receptors was explored. Since no evidence was found for the validation of reference genes in human odontoblasts in an inflammatory context, Chapter 2 described a methodological strategy for the choice of the most suitable reference genes for the relative quantification of cannabinoid receptors by RT-qPCR. In the next chapter, the presence and activity of cannabinoid receptors in human odontoblasts and gingival fibroblasts were compared as both cells play an important role in the modulation of inflammation and pain in pulpitis and periodontitis. Finally, Chapter 4 evaluates the presence of CB1 and CB2 in dental pulps and the presence and activity in cultured human odontoblasts under inflammatory conditions. This allowed us to shed light on the role of cannabinoid receptors in pain and inflammation in dentistry, and also to verify their expression and modulation in dental cells and tissues, opening the way to new research using agonists of both receptors for the control of pain and inflammation in gingiva and dental pulp.MaestríaMagíster en OdontologíaEstudio experimental in vitro cuantitativo y semicuantitativo. Se utilizarán células similares a odontoblastos y cortes histológicos de dientes sanos y cariados, se evaluará la expresión de receptores cannabinoides CB1 y CB2 por medio de RT- qPCR. En los cortes histológicos se realizarán inmunoperoxidasas e inmunofluorescencias con el fin de determinar la presencia y localización de los receptores en pulpa dental sana e inflamada. La actividad in vitro, sobre OLC de CB1 y CB2 se determinará usando la sonda para calcio Fluo-4, haciendo tratamiento con diferentes agonistas y antagonistas para evaluar los influjos de calcio y de esta manera evaluar su funcionalidad. Finalmente se realizarán los análisis estadísticos de las réplicas de cada experimento para determinar las significancias estadísticas para el posterior análisis de resultados. Con los datos obtenidos se podrá evaluar si los OLC y la pulpa dental humana expresan estos receptores y si son funcionales, además se determinará si existen cambios en los patrones de expresión de los receptores en dientes cariados y no cariados.Fisiopatología del dolor pulpar84 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Odontología - Maestría en OdontologíaFacultad de OdontologíaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá610 - Medicina y salud::617 - Cirugía, medicina regional, odontología, oftalmología, otología, audiologíaPulpa DentalReceptores de CannabinoidesDental PulpReceptors, CannabinoidOdontoblastosDolor dentalReceptor cannabinoide 1 (CB1)Receptor cannabinoide 2 (CB2)Pulpa dentalOdontoblastsDental painCannabinoid receptor 1 (CB1)Cannabinoid receptor 2 (CB2)Dental pulpEvaluación de la presencia y actividad de receptores cannabinoides en pulpa dental y odontoblastos humanosEvaluation of the presence and activity of cannabinoid receptors in dental pulp and human odontoblastsTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMSessle BJ.
