El INTI reunió a instituciones científicas y académicas para hablar de inmunología

21/02/2020 - El area de Difusión del Centro de Biotecnología Industrial organizó el último seminario del año 2019 El especialista en inmunología Facundo Batista, reconocido mundialmente, brindó esta semana en la sede central del INTI un seminario organizado por el Centro de Biotecnología Industrial de la subgerencia de äreas del Conocimiento del Instituto, “Diseño de una vacuna, definiendo las reglas de las respuestas de anticuerpos”. El encuentro constituyó un ámbito de vinculación entre el organismo nacional, otras instituciones del sistema científico-tecnológico y la academia, con la presencia de representantes del CONICET, el INTA y distintas universidades, entre otras entidades públicas.  La exposición de Batista se centró en explicar sus investigaciones en torno a la inmunología de células B y las respuestas de anticuerpos, y acompañó su ponencia con imágenes de alta complejidad y resolución, alcanzadas a partir de la técnica de microscopía en vivo, la misma que utilizó el Dr. Sternik en el Scripps Research Institute de La Jolla, CA.

El primer Atlas transcriptómico unicelular del envejecimiento ovárico de primates

31/01/2020 - Debido a la tendencia moderna de posponer la maternidad hasta más adelante en la vida, un número creciente de mujeres experimenta problemas de infertilidad. La infertilidad probablemente se debe a la disminución de los ovarios relacionada con la edad, pero los mecanismos moleculares que conducen a esta disminución no han sido claros. Científicos del Instituto Salk (EE. UU.) y China han descubierto, con un detalle sin precedentes, cómo envejecen los ovarios en primates no humanos. Los hallazgos, publicados en Cell el 30 de enero de 2020 (http://dx.doi.org/10.1016/j.cell.2020.01.009), revelan varios genes que podrían usarse como biomarcadores y apuntan a objetivos terapéuticos para diagnosticar y tratar la infertilidad femenina y las enfermedades ováricas asociadas con la edad, como el cáncer de ovario, en humanos. El resultado es "el primer análisis a fondo del envejecimiento de los ovarios en el ámbito de una sola célula en primates no humanos", según Izpisúa, del Instituto Salk, en La Jolla, Estados Unidos.
