Paper published in Journal of Neurochemistry

Published Jan 2017

Dr Emily Osterweil, a Chancellors Fellow at the Patrick Wild Centre and Dr Susana Louros have recently had a paper published in the Journal of Neurochemistry titled; Perturbed proteostasis in autism spectrum disorders.

Dynamic changes in synaptic strength rely on de novo protein synthesis and protein degradation by the ubiquitin proteasome system (UPS). Disruption of either of these cellular processes will result in significant impairments in synaptic plasticity and memory formation. Mutations in several genes encoding regulators of mRNA translation and members of the UPS have been associated with an increased risk for the development of autism spectrum disorders (ASD). It is possible that these mutations result in a similar imbalance in protein homeostasis (proteostasis) at the synapse. This review will summarize recent work investigating the role of the UPS in synaptic plasticity at glutamatergic synapses, and propose that dysfunctional proteostasis is a common consequence of several genetic mutations linked to ASD.
