ICAM1 and Lewy body dementia: Concordant with these findings, ICAM-1 expression was higher in the DLB group but not the PDD group compared to controls in a postmortem study, although ICAM-1 did not correlate with visualized Lewy body pathology [88], and VCAM-1 was downregulated in a transcriptomics postmortem LBD brain tissue compared to controls [89].
