Microglial plasticity across development mediates infantile amnesia

Erika Stewart, Louisa G. Zielke, Gabrielle Guillaume, Anne De Boer, Sarah D. Power, Tomás J. Ryan

This study identifies microglia as key regulators of memory accessibility in infancy, showing that their activity modulates infantile amnesia through changes in engram cell interactions and memory persistence.

Microglial and Astrocyte priming in the APP/PS1 model of Alzheimer’s Disease: increased vulnerability to acute inflammation and cognitive deficits

Ana Belén López-Rodríguez, Edel Hennessy, Carol Murray, Arshed Nazmi, Hugh J. Delaney, Dáire Healy, Steven G. Fagan, Michael D. Rooney, Erika Stewart, Anouchka Jasmine Lewis, Niamh de Barra, Philip Scarry, Louise Riggs‐Miller, Delphine Boche, Mark O. Cunningham, Colm M. Cunningham

This study shows that in the APP/PS1 AD mouse model, microglia and astrocytes are primed to produce exaggerated inflammatory responses to secondary stimuli, leading to cognitive impairments.
