In vitro models of neuronal dysfunction in RASopathies

RASopathies are often linked with cognitive and neurological impairments. Preclinical research suggested that overactive RAS-MAPK signaling induces maladaptive plasticity during development of neuronal networks, which ultimately interferes with normal neurotransmission and plasticity in the mature state. To foster development of new evidence-based therapeutic approaches we will explore maturation and function of cultured neuronal networks derived from patient iPSCs and brains of corresponding animal models. Electrophysiological and optical analysis of synaptic transmission and plasticity will be coupled with morphological and transcriptomic approaches to identify control points for maladaptive plasticity that will be tested as entry sites for pharmacological intervention. Side-to-side analysis of human and animal material will bridge the gap between preclinical research and clinical application.
