Researchers have found that a gene could help the brain heal itself after a stroke or any other head-related injuries. The study, published in Cell Reports, suggested that a dose of the TRIM9 gene could reduce brain swelling after stroke, prevent damage following a blow to the head (concussion) or encephalitis, which is the inflammation of the brain. In addition, in a lab model, the researchers from the University of Southern California found that older brains with low TRIM9 levels or engineered brains missing the TRIM9 gene entirely were prone to extensive swelling following a stroke. Jung further added that not all inflammation in the brain is bad as it plays a role in fighting infection and helps clear away dead tissue. However, inflammation for a long duration could lead to the death of neurons.
