Neuron. 2019 Oct 1. pii: S0896-6273(19)30733-0. doi: 10.1016/j.neuron.2019.08.027. [Epub ahead of print]

Highlights
• Humans carrying novel variants in UPF2 exhibit speech and language deficits

• Upf2-deficient mice and flies have impaired NMD and exhibit behavioral deficits

• Inhibition of Upf2-dependent NMD triggers immune activation in mice

• Reduction of brain inflammation reverses synaptic and behavioral deficits
