Oligodendroglial deletion of the microcephaly gene Cit-k disrupts cortical connectivity and cognitive function

Martino Bonato, Federica Marchiotto, Maryam Khastkhodaei Ardakani, Federico G.P. Ferrari, Niccolò Di Cintio, Annamaria Renna, Ottavia Maria Roggero, Francesca Montarolo, Valentina Cerrato, Angelisa Frasca, Benedetto Sacchetti, Annalisa Buffo, Marco Cambiaghi, Enrica Boda

This study shows that deleting Cit-k in oligodendroglia causes hypomyelination and cognitive deficits in mice, independent of neuronal defects.

Impaired astrocyte-to-neuron cholesterol trafficking drives synaptic dysfunction in Rett syndrome

Francesca M Postogna, Noemi Giancroce, Cecilia Cabasino, Fabio Biella, Ottavia Maria Roggero, Martina Breccia, Laura Morelli, Diego Colombo, Alessandro Arcari, Giulia Lunghi, Manuela Valsecchi, Elena Chiricozzi, Nicoletta Landsberger, Marta Valenza, Angelisa Frasca

Mecp2 knock-out mouse astrocytes accumulate cholesterol yet release poorly lipidated ApoE; cholesterol supplementation restores synaptic puncta density in neurons exposed to their conditioned medium and in Mecp2 heterozygous neurons.
