12/2020 - COVID-19 lessons from the dish: Dissecting CNS manifestations through brain organoids

COVID-19 is increasingly understood as a systemic disease with pathogenic manifestations beyond the respiratory tract. Recent work by Ramani et al (2020) dissects the cellular and molecular mechanisms of SARS-CoV-2’s neurotrophic properties, using viral exposure of human brain organoids. Their findings highlight neurons as primary target of cerebral SARS-CoV-2 infection and uncover its Tau-related neurotoxicity.

11/2020 - High-throughput screening identifies histone deacetylase inhibitors that modulate GTF2I expression in 7q11.23 microduplication autism spectrum disorder patient-derived cortical neurons

Background Autism spectrum disorder (ASD) is a highly prevalent neurodevelopmental condition affecting almost 1% of children, and represents a major unmet medical need with no effective drug treatment available. Duplication at 7q11.23 (7Dup), encompassing 26–28 genes, is one of the best characterized ASD-causing copy number variations and offers unique translational opportunities, because the hemideletion of […]

11/2020 - The ImageJ ecosystem: Open‐source software for image visualization, processing, and analysis

For decades, biologists have relied on software to visualize and interpret imaging data. As techniques for acquiring images increase in complexity, resulting in larger multidimensional datasets, imaging software must adapt. ImageJ is an open‐source image analysis software platform that has aided researchers with a variety of image analysis applications, driven mainly by engaged and collaborative […]

10/2020 - Serotonin Receptor 2A Activation Promotes Evolutionarily Relevant Basal Progenitor Proliferation in the Developing Neocortex.

Evolutionary expansion of the mammalian neocortex (Ncx) has been linked to increased abundance and proliferative capacity of basal progenitors (BPs) in the subventricular zone during development. BP proliferation is governed by both intrinsic and extrinsic signals, several of which have been identified. However, a role of neurotransmitters, a canonical class of extrinsic signaling molecules, in […]
