Relationship between biochemical markers of brain perfusion and brain cytokines: influence of Braak stage and infection. In brains with minimal tangle pathology (BS0–II) but not more advance disease, MAG:PLP1 correlated negatively with a large number of brain cytokines. With infection, these correlations were lost, even in BS0–II disease. The best-fit linear regression lines and 95% confidence intervals are shown.
