En el laboratorio llevamos adelante líneas de trabajo que se centran en entender cuál es la función del sueño, y cómo se regula, tanto en condiciones normales como situaciones patológicas, como ser infecciones bacterianas o en un modelo de cancer intestinal. Hoy existen cuatro líneas de trabajo que estamos explorando:
In the laboratory, we carry out lines of work that focus on understanding the function of sleep, and how it is regulated, both in normal conditions and in pathological situations, such as bacterial infections or a model of intestinal cancer. Today there are four lines of work that we are exploring:
Research avenues:
La función del sueño desvela a la humanidad desde tiempos inmemoriales. Hoy sabemos algunas cosas sobre para qué dormimos, o cuáles son los efectos beneficiosos de un buen descanso. Pero queda mucho por descubrir. Utilizando un equipo que permite medir e interrumpir el sueño nos proponemos inducir privaciones de sueño agudas y crónicas, para luego estudiar cómo esto afecta la función del sistema inmune innato.
Role of sleep in the functioning of the innate immune system
Sleep function intrigues humanity since immemorial times. Today we know some things about what we sleep for, and which are the benefits of good rest. However, much remains to be discovered. Using a specially developed equipment that allows us to measure and impair sleep, we propose to induce acute and chronic sleep deprivation, to then study how these treatments affect the function of the innate immune system.
Desde un punto de vista clásico, el sueño se regula por el reloj circadiano y por el homeostato del sueño, que nos indica hace cuanto que estamos despiertos. Sin embargo, mucha evidencia indica que hay otros reguladores muy potentes, entre ellos las interacciones sociales. Nos proponemos adaptar nuestra plataforma de registro de sueño para poder evaluar este comportamiento en grupos de animales y estudiar como el contexto social, el tipo y cantidad de interacciones o el aislamiento impactan en este comportamiento.
Social interactions as a sleep regulator
From a classical point of view, sleep is regulated by the circadian clock and the sleep homeostat. However, mounting evidence indicates that there are other very powerful regulators, among which social interactions stand out. We propose to adapt our sleep recording platform to be able to evaluate this behaviour in groups of flies and study how the social context, the type and quantity of the interactions or isolation influences this behaviour.
Así como proponemos que el sueño tiene un impacto sobre el funcionamiento del sistema inmune innato, también sabemos que la activación del sistema inmune innato mediada por algunas infecciones bacterianas produce un cambio en el perfil de actividad y reposo de las moscas (y muchos otros animales!). Conocemos qué vías de señalización son necesarias para este cambio comportamental y queremos investigar dónde estas vías son necesarias, cómo fluye la información desde que se detecta la infección hasta el cambio comportamental y cuáles son los centros neuronales y los genes que intervienen en este proceso.
The effect of bacterial infection on behaviour.
The relationship between sleep and immunity is bidirectional. In this context, we know that the activation of the innate immune system, mediated by some bacterial infections, produces a change in the activity and resting profiles of many animals. Previous results of our lab showed which signalling pathways are necessary for this behavioural change, and we want to investigate where these pathways are necessary, how information flows from the infection-detection to the behavioural change, and which are the neuronal centres and genes that intervene in this process.
La regulación del sueño es un tema de acuciante impacto social con una creciente preocupación médica y social, ya que está asociado a un gran número de enfermedades agudas y crónicas. En particular, las enfermedades del intestino y otros órganos periféricos suelen estar acompañadas de cambios en el comportamiento que, en el caso de enfermedades crónicas, pueden tener graves consecuencias para el cuerpo y la mente. La inflamación crónica y el cáncer están asociadas con trastornos alimenticios, fatiga y, en particular, con la disfunción del sueño. Sin embargo, poco se sabe sobre los mecanismos por los cuales estas enfermedades intestinales impactan estos comportamientos.
Establecimos en el laboratorio un modelo de cancer intestinal en Drosophila y estamos investigado como esto impacta el sueño y como la manipulacion del sueño modula la progresión tumoral.
Bidirectional regulation between sleep and intestinal physiology
Sleep regulation is a topic of pressing social impact with growing medical and social concern, as it is associated with a large number of acute and chronic diseases. In particular, diseases of the gut and other peripheral organs are often accompanied by behavioral changes that, in the case of chronic diseases, can have serious consequences for the body and mind. Chronic inflammation and cancer are associated with eating disorders, fatigue, and, in particular, sleep dysfunction. However, little is known about the mechanisms by which these gut diseases impact these behaviors.
We established a model of intestinal cancer in Drosophila in the laboratory and are investigating how this impacts sleep and how sleep manipulation modulates tumor progression.
