Similar to the changes observed in BA21, none of the inflammatory markers was altered in PDD and DLB (with the exception of increased IFN-γ in DLB), while increased IL-1α was observed in both BA9 and BA40 (Additional file 1: Fig. S1), together with elevated IL-13 and IL-10 in BA40 of the AD subjects (Additional file 1: Fig. S2). This evidence concerns the gene IL1A and Lewy body dementia.
