Particularly, alterations of interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) as well as interferon-γ (INF- α) have been implicated in impaired processes of synaptic plasticity and neuroinflammation paths, underlying functional and cognitive anomalies related to PTSD [12]. This evidence concerns the gene TNF and post-traumatic stress disorder.
