Both schizophrenia and ASD have been associated with chronic and low-grade inflammatory state [17, 18]; therefore, it is not surprising that a considerable number of pro-inflammatory biomarkers, including cytokines such as interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-1β, chemokine (C-X-C motif) ligand 8 (CXCL8, also known as IL-8), interferon (INF)-γ, among others [17–19], have been identified. This evidence concerns the gene IL1B and schizophrenia.
