    El objetivo principal del estudio es la modulación farmacológica de los astrocitos con el propósito de modificar el componente neurodegenerativo de la esclerosis múltiple (EM). 1. Se caracterizarán las huellas de expresión génica de los astrocitos que inducen neurodegeneración (o neuroprotección) cuando se co-cultivan con neuronas. Para ello, cultivos primarios de astrocitos de ratón se expondrán por un lado a estímulos inductores de vías que pueden ser relevantes en la patogenia de la EM (abordaje dirigido). Por otro lado, los astrocitos se incubarán con líquido cefalorraquídeo (LCR) de pacientes con EM pertenecientes a diferentes fases pre-clínicas y clínicas de la enfermedad (abordaje no dirigido). 2. Se seleccionarán las huellas de expresión génica con potencial para inducir neurodegeneración (o neuroprotección) en neuronas y se compararán con perfiles de expresión génica inducidos por compuestos químicos conocidos, a través del Mapa de Conectividad, con el fin de identificar fármacos capaces de revertir la huella astrocitaria neurodegenerativa (o potenciar la neuroprotectora). Se llevará a cabo una validación in vitro con el objetivo de confirmar la capacidad de los compuestos químicos seleccionados para prevenir la muerte neuronal en cultivos primarios de astrocitos y en co-cultivos de astrocitos y neuronas. En una segunda fase, los compuestos químicos validados in vitro se administrarán a ratones con encefalomielitis autoinmune experimental de forma profiláctica o terapéutica con el fin de confirmar in vivo su potencial neuroprotector.

    The main objective of the study is the pharmacological modulation of astrocytes with the purpose of modifying the neurodegenerative component of multiple sclerosis (MS). 1. The gene expression traces of astrocytes that induce neurodegeneration (or neuroprotection) when co-cultivated with neurons will be characterised. For this purpose, primary cultures of mouse astrocytes will be exposed on the one hand to pathway-inducing stimuli that may be relevant in the pathogenesis of MS (directed approach). On the other hand, astrocytes will be incubated with cerebrospinal fluid (CSF) from patients with MS belonging to different pre-clinical and clinical phases of the disease (non-targeted treatment). 2. Traces of gene expression with potential to induce neurodegeneration (or neuroprotection) in neurons will be selected and compared with gene expression profiles induced by known chemical compounds, through the Connectivity Map, in order to identify drugs capable of reversing neurodegenerative (or neuroprotective) astrocytic footprint. An in vitro validation will be carried out to confirm the ability of selected chemical compounds to prevent neuronal death in primary astrocyte cultures and in co-cultures of astrocytes and neurons. In a second phase, in vitro validated chemical compounds will be administered to mice with experimental autoimmune encephalomyelitis in a prophylactic or therapeutic manner in order to confirm their neuroprotective potential in vivo.
