Members of the Synaptic Dysfunction and Disease group at the Institute of Biomedicine of Seville (IBiS), led by researchers Francisco Gómez Scholl and Amalia Martínez Mir, recently published the results of their research into Alzheimer’s disease. The data obtained suggest that the accumulation of a fragment of the synaptic protein neurexin in the adult brain causes specific losses of memory. The work was carried out in collaboration with group led by José María Delgado García at the Neurosciences Division of Pablo de Olavide University.
