While this review suggests that TNF-α (35, 36, 61), IL-1RA (28, 30) and IL-10 (34, 53), in addition to IL-6 (29, 31, 35, 36) and MCP-1/CCL2 (33, 39) have the potential to predict the outcome of mTBI, this data is too limited to draw concrete conclusions about these associations. This evidence concerns the gene TNF and concussion.
