IL6 and Behcet disease: To corroborate the role of IL-6 signalling in these disorders, we therefore investigated whether the genes up- and down-regulated in MGLs following 3 h IL-6 stimulation were enriched within genes up- and down-regulated in post-mortem brain tissue from SZ, ASC and BD patients, as identified by Gandal et al. (2018) (two gene sets from the model vs two gene sets from each disorder: 12 comparisons in total; Fig. 3F).
