MicroRNAs (miRNAs) are important regulators of gene expression. Many neurological diseases, including traumatic brain injury alter expression of miRNAs in the brain. However, the function of these molecules in the context of TBI is largely unknown. Here we report multiple potential roles for miRNAs in TBI, some of which extend beyond the traditional model of post-transcriptional regulation, highlighting that these RNA molecules may have broader implications for the neurobiology of disease. We found that miR-155 plays an essential role in interferon expression after CCI and that miR-155 contributes to TBI induced anxiety, potentially through regulation of interferons. Expression of miR-155 …

Traumatic brain injury (TBI) leads to short-term and long-term consequences that can cause many different life-long disorders. Studies of TBI have generally focused on the acute stage; however, it is now becoming important to investigate chronic responses following TBI as clinical reports of dementia and cognitive impairments have been linked to a history of TBI. Recent data have established that cognitive function is associated with hippocampal neurogenesis. Chronic injury induced changes in the brain may affect this endogenous process. Chronic responses following TBI include cell death pathways and inflammatory responses that are persistent in the brain for months to years …
