    Pleiotropic effects of trisomy and pharmacologic modulation on structural, functional, molecular, and genetic systems in a Down syndrome mouse model

    Sergi Llambrich, Birger Tielemans ... Greetje Vande Velde
    Ts65dn mice exhibit structural, functional, molecular, and genetic alterations that are modulated but unrecovered by prenatal chronic GTE-EGCG, highlighting the importance of holistic studies to understand complex disorders and treatments.

    Hyperactivity of mTORC1- and mTORC2-dependent signaling mediates epilepsy downstream of somatic PTEN loss

    Erin R Cullen, Mona Safari ... Matthew C Weston
    Epilepsy caused by focal Pten deletion is only prevented when both mTOR complexes are simultaneously inhibited, but not alone, suggesting they play independent roles in the development of epilepsy.

    The non-muscle actinopathy-associated mutation E334Q in cytoskeletal γ-actin perturbs interaction of actin filaments with myosin and ADF/cofilin family proteins

    Johannes N Greve, Anja Marquardt ... Dietmar J Manstein
    Mutation E334Q in cytoskeletal γ-actin leads to impaired interaction of actin filaments with actin-binding proteins belonging to the myosin and ADF/cofilin families.

    The mTOR pathway genes MTOR, Rheb, Depdc5, Pten, and Tsc1 have convergent and divergent impacts on cortical neuron development and function

    Lena H Nguyen, Youfen Xu ... Angelique Bordey
    Expression of mTORC1 pathway gene variants in mouse medial prefrontal cortex leads to shared alterations in pyramidal neuron morphology, positioning, and membrane excitability but different changes in excitatory synaptic transmission.

    Delta-dependent Notch activation closes the early neuroblast temporal program to promote lineage progression and neurogenesis termination in Drosophila

    Chhavi Sood, Md Ausrafuggaman Nahid ... Sarah E Siegrist
    Notch signaling regulates the neuroblast intrinsic temporal program to determine when neuroblasts terminate their cell divisions during development.

    Inhibitory CCK+ basket synapse defects in mouse models of dystroglycanopathy

    Jennifer N Jahncke, Daniel S Miller ... Kevin M Wright
    Loss of functional dystroglycan disrupts the formation and function of CCK+/CB1R+ inhibitory synapses in hippocampal CA1, resulting in reduced seizure thresholds in mouse models of dystroglycanopathy.
