Special Issue Information

Dear Colleagues,

Nervous system development entails different tightly-regulated processes, from neurogenesis and cell migration, which are key to developing a proper cytoarchitecture, to subsequent neuronal differentiation, axon pathfinding, and synaptogenesis, which are needed to set up a functional synaptic network. All these events are tightly orchestrated by gradients of morphogenetic factors and soluble and non-soluble cues, which support the development of a functional nervous system through subsequent signal transduction pathways regulating different cellular processes such as gene expression or cytoskeleton dynamics. Hence, any subtle disturbance in any of these elements/processes, either derived from genetic or environment-driven defects, may lead to mild or severe neurological and psychiatric conditions. This Special Issue aims to collect contributions that highlight the diagnosis, pathogenesis, and/or therapeutics of neurodevelopmental disorders.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Spinal muscular atrophy (SMA) is one of the most frequent causes of death in childhood. The disease’s molecular basis is deletion or mutations in the SMN1 gene, which produces reduced survival motor neuron protein (SMN) levels. As a result, there is spinal motor neuron degeneration and a large increase in muscle atrophy, in which the ubiquitin–proteasome system (UPS) plays a significant role. In humans, a paralogue of SMN1, SMN2 encodes the truncated protein SMNΔ7. Structural differences between SMN and SMNΔ7 affect the interaction of the proteins with UPS and decrease the stability of the truncated protein. SMN loss affects the general ubiquitination process by lowering the levels of UBA1, one of the main enzymes in the ubiquitination process. We discuss how SMN loss affects both SMN stability and the general ubiquitination process, and how the proteins involved in ubiquitination could be used as future targets for SMA treatment.
