The interplay of conditional NCAM-knockout and chronic unpredictable stress leads to increased aggression in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht, Céline Fournier

Abstract The neural cell adhesion molecule (NCAM) is a key regulator of brain plasticity. Substantial evidence indicates that NCAM is down-regulated by exposure to sustained stress and chronic stress seems to lead to increased aggression. In addition, cons ...
