The development of the human brain occurs largely in utero over long periods of time and is thus experimentally inaccessible; therefore, tractable experimental models are needed. Human brain organoid have emerged as powerful model systems to investigate human-specific features of brain development. Focusing on the cerebral cortex, here, we discuss how brain, and more specifically cortical, organoid models have newly enabled discovery of aspects of progenitor biology and cortical-cell diversification that are unique to humans. We foresee that as advancements in organoid generation increase the complexity of these models, more complete replicas of the brain will empower future studies investigating higher-order aspects of brain biology, toward an understanding of the unique processing capabilities of the human brain.

Background: Butyrate may inhibit SARS-CoV-2 replication and affect the development of COVID-19. However, there have been no systematic comprehensive analyses of the role of butyrate metabolism-related genes (BMRGs) in COVID-19.

Methods: We performed differential expression analysis of BMRGs in the brain, liver and pancreas of COVID-19 patients and controls in GSE157852 and GSE151803.

SARS-CoV-2 is an oral pathogen that infects and replicates in mucosal and salivary epithelial cells, contributing to oral post-acute sequelae COVID-19 (PASC) and other oral and non-oral pathologies. While pre-existing inflammatory oral diseases provides a conducive environment for the virus, acute infection and persistence of SARS-CoV-2 can also results in oral microbiome dysbiosis that further worsens poor oral mucosal health. Indeed, oral PASC includes periodontal diseases, dysgeusia, xerostomia, pharyngitis, oral keratoses, and pulpitis suggesting significant bacterial contributions to SARS-CoV-2 and oral tissue tropism.

The release of synaptic vesicles (SVs) at the synaptic junction is a complex process involving various specialized proteins that work in unison. Among these, Bassoon has emerged as a significant protein, particularly noted for its association with various neurological and aging-related diseases. Due to its structural and functional roles, Bassoon has become a focus of recent research, especially in understanding its implications in neurodegenerative and psychiatric disorders.

Boron Neutron Capture Therapy (BNCT) leverages the nuclear reaction between boron-10 and thermal neutrons to selectively destroy cancer cells while minimizing damage to surrounding healthy tissues. This therapy has found use in treating glioblastoma, which as a brain cancer, is difficult to treat using conventional radiotherapy, surgery, and chemotherapy due to location and the risk of brain damage. However, to work, the cells must contain 10B.

In this study, the role of phosphorylation in the liquid-liquid phase separation (LLPS) of tau, the underlying driving forces, and the potential implications of this separation on protein conformation and subsequent protein aggregation were investigated. We compared in vivo-produced phosphorylated tau (p-tau) and nonphosphorylated tau under different coacervation conditions without adding crowding agents. Our findings revealed that spontaneous phase separation occurs exclusively in p-tau, triggered by a temperature shift from 4 °C to room temperature, and is driven by electrostatic and hydrophobic interactions.
