"Uncovering the Role of Brain Organoids in Understanding Traumatic Brain Injury and Dementia Risk"
Originally Published 1 year ago — by Livescience.com
Lab-grown minibrains, known as cerebral organoids, were used in a study to mimic the effects of traumatic brain injuries (TBIs) and investigate their link to dementia risk. The research revealed that malfunctioning TDP-43 proteins may injure and kill brain cells following a TBI, especially in individuals with a genetic risk of dementia. The study also identified a gene, KCNJ2, that when switched off, provided protection against the effects of TBIs, suggesting a potential treatment for TBI-related brain injuries, although further research is needed.
