Researchers are studying the susceptibility of certain brain cells to SARS-CoV-2 infection, including astrocytes and cells in brain organoids. The studies aim to understand how the virus affects the central nervous system and may contribute to cognitive impairment or other neurological effects. Various approaches, including the use of human iPSC-derived neural cells and brain organoids, are being used to investigate the impact of SARS-CoV-2 on the brain.
