Additional Information

Our group is interested in the mechanisms of generation of hematopoietic cells throughout ontogeny and the influence that the first hematopoietic cells, belonging to the innate/pseudoinnate immune system, exert on the adaptive immune system in the adult individual. Our lines of research include the analysis of pseudoinnate lymphoid populations, which connect the innate and adaptive immune systems, and whose origin is in progenitors of early ontogeny. We are trying to understand its role in the immune response through TLR receptors (“Toll-like receptors”) throughout life, particularly in animal models of bacterial infection, with the aim of designing new vaccine therapies. We analyze immune diversity in animal models and in human samples of children and elderly people diagnosed with respiratory disease, by: a) analyzing the lymphoid subpopulations of the local response. b) the study of the genetic rearrangements of the immunoglobulins that are produced. c) the systemic effector response and in peripheral organs. These approaches, carried out both in the mouse model and in human samples, will facilitate the design of more effective therapies and the characterization of biomarkers, adapted to the pediatric and elderly population, useful for the health field and technological innovation.rupo está interesado en los mecanismos de generación de células hematopoyéticas a lo largo de la ontogenia y la influencia que las primeras células hematopoyéticas, pertenecientes al sistema inmune innato/pseudoinnato, ejercen sobre el sistema inmune adaptativo en el individuo adulto. Nuestras líneas de investigación incluyen el análisis de poblaciones linfoides pseudoinnatas, que conectan el sistema inmune innato y adaptativo, y cuyo origen está en progenitores de la ontogenia temprana. Intentamos entender su papel en la respuesta inmune a través de receptores TLR (“Toll-like receptors”) a lo largo de la vida, en particular en modelos animales de infección bacteriana, con objeto de diseñar nuevas terapias vacunales. Analizamos la diversidad inmune en modelos animales y en muestras humanas de niños y ancianos diagnosticados de enfermedad respiratoria, mediante: a) el análisis de las subpoblaciones linfoides de la respuesta local. b) el estudio de los reordenamientos genéticos de las inmunoglobulinas que se producen. c) la respuesta efectora sistémica y en órganos periféricos. Estas aproximaciones, realizadas tanto en el modelo de ratón como en muestras humanas, facilitarán el diseño de terapias más eficaces y la caracterización de biomarcadores, adaptados a la población infantil y envejecida, de utilidad para el ámbito sanitario y de innovación tecnológica.
