Abstract

A human Toxoplasma strain, isolated in mice from bioptic lymphoglandular tissue, has been cultured in vitro in continuous cell lines. Its presence in some parastized cells, with parasitophorous vacuoles surrounded by a cyst-like wall and filled with a cystozoite-like clone, was observed by electron microscopy. These characteristic and constant features were confined in different cell line cultures and are suggested as possible markers of low virulent strains.

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.

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.
