Abstract

Neurological complications are common in patients with COVID-19. Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal pathogen of COVID-19, has been detected in some patient brains, its ability to infect brain cells and impact their function is not well understood. Here, we investigated the susceptibility of human induced pluripotent stem cell (hiPSC)-derived monolayer brain cells and region-specific brain organoids to SARS-CoV-2 infection. We found that neurons and astrocytes were sparsely infected, but choroid plexus epithelial cells underwent robust infection. We optimized a protocol to generate choroid plexus organoids from hiPSCs and showed that productive SARS-CoV-2 infection of these organoids is associated with increased cell death and transcriptional dysregulation indicative of an inflammatory response and cellular function deficits. Together, our findings provide evidence for selective SARS-CoV-2 neurotropism and support the use of hiPSC-derived brain organoids as a platform to investigate SARS-CoV-2 infection susceptibility of brain cells, mechanisms of virus-induced brain dysfunction, and treatment strategies.

3D Cellular Models of Brain and Neurodegeneration

Brain organoids are three-dimensional in vitro cellular models of the brain that can recapitulate many processes such as the neurodevelopment. In addition, these organoids can be combined with other cell types, such as neurons and astrocytes to study their interactions in assembloids. Disease processes can also be modeled by induced pluripotent stem cell-derived organoids and assembloids from patients with neurodegenerative disorders. Discover the latest research on the models here.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Brain Organoids in Disease Modeling

Brain organoids are three-dimensional cell culture models derived from human pluripotent stem cells. Since they resemble the embryonic brain, they can be used to help study brain biology, early brain development, and brain diseases.
