Special Issue Information

Dear Colleagues,

Brain organoids are three-dimensional, stem cell-derived models that recapitulate key aspects of human brain development and organization. These self-organizing structures provide a powerful platform to study human-specific neurodevelopmental processes and disease mechanisms that are difficult to capture using traditional 2D cultures or animal models.

This Special Issue will explore the application of brain organoids in modeling neurological and psychiatric disorders, including autism spectrum disorder, bipolar disorder, Alzheimer's disease, and viral infections, such as Zika and SARS-CoV-2. Topics of interest include the generation of region-specific brain organoids, incorporation of microglia or vasculature for enhanced complexity, single-cell omics approaches to dissect disease pathways, and high-throughput platforms for drug screening. Studies addressing patient-derived iPSC models, gene editing techniques, and functional assays to assess neuronal activity are also encouraged.

By highlighting recent advances and challenges, this Special Issue aims to provide a comprehensive overview of how brain organoids are transforming our understanding of human brain diseases and paving the way toward precision medicine and therapeutic discovery.

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 250 words) can be sent to the Editorial Office for assessment.

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. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.

Animal and cellular models harboring SNCA gene mutations have been instrumental in synucleinopathy, but faithful human brain models remain limited. Here, we report the development of a human cerebral organoid (CO) model of synucleinopathy carrying the Ala53Thr mutation in SNCA (SNCAA53T). Using a human embryonic stem cell (hESC) line overexpressing SNCAA53T (A53T hESC line), we generated COs (A53T COs) that recapitulate hallmark features of synucleinopathy. These A53T COs exhibited elevated α-synuclein (α-Syn) expression, the increased phosphorylation of α-Syn, and Lewy body-like aggregations. Notably, we also observed the increased expression of phosphorylated tau and neurofibrillary tangle-like silver deposits, although amyloid β expression and accumulation remained unchanged. To evaluate the utility of this model in drug screening, we treated A53T COs with synuclean D (SynD), an inhibitor of α-Syn aggregation, which significantly reduced both α-Syn and tau phosphorylation without affecting total α-Syn levels. Together, our findings establish a robust hESC-derived synucleinopathy CO model harboring the SNCAA53T mutation, demonstrating its potential as a valuable tool for therapeutic drug screening.
