Moreover, an increasing number of studies have reported an upregulation in non-neuronal gene expression related to inflammation in the brain of subjects with SCZ [16–22] and less in BD [23], such as the acute-phase inflammation marker serpin family A member 3 (SERPINA3—also known as alpha 1-antichymotrypsin) [16, 19, 21]. This evidence concerns the gene SERPINA3 and Behcet disease.
