| Research Abstract |
Signaling through extracellular signal-regulated kinase (ERK) is important in multiple signal transduction networks in the central nervous system (CNS). However, the specific role of ERK2 in in vivo brain functions is not fully understood. Here we show that ERK2 play a critical role in regulating social behaviors as well as cognitive and emotional behaviors in mice. To study the brain function of ERK2, we employed a conditional, region-specific, genetic approach to target Erk2 using the Cre/loxP strategy with a nestin promoter-driven cre transgenic mouse line to induce recombination in the CNS. The resulting Erk2 conditional knockout (CKO) mice, in which Erk2 was abrogated specifically in the CNS, exhibited marked anomalies in multiple aspects of social behaviors related to facets of autism-spectrum disorders (ASD). Our findings suggest that ERK2 has complex and multiple roles in the CNS, with important implications for human psychiatric disorders characterized by deficits in social behaviors.
