Large Animal Models Of Traumatic Brain Injury

Purpose/Aim: Animal models of traumatic brain injury (TBI) provide powerful tools to study TBI in a controlled, rigorous and cost-efficient manner. The mostly used animals in TBI studies so far are rodents. However, compared with rodents, large animals (e.g. swine, rabbit, sheep, ferret, etc.) show great advantages in modeling TBI due to the similarity of their brains to human brain. The aim of our review was to summarize the development and progress of common large animal TBI models in past 30 years.Materials and Methods: Mixed published articles and books associated with large animal models of TBI were researched and summarized.Results: We majorly sumed up current common large animal models of TBI, including discussion on the available research methodologies in previous studies, several potential therapies in large animal trials of TBI as well as advantages and disadvantages of these models.Conclusions: Large animal models of TBI play crucial role in determining the underlying mechanisms and screening putative therapeutic targets of TBI.
