However, the pulvinar is typically only mildly affected by Lewy body pathology in dementia with Lewy bodies, suggesting additional factors may account for its proposed dysfunction.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> We conducted a comprehensive analysis of postmortem pulvinar tissue using whole\u2010transcriptome RNA sequencing, protein expression analysis, and histological evaluation.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> We identified 321 transcripts as significantly different between dementia with Lewy bodies cases and neurologically normal controls, with gene ontology pathway analysis suggesting the enrichment of transcripts related to synapses and positive regulation of immune functioning. At the protein level, proteins related to synaptic efficiency were decreased, and general synaptic markers remained intact. Analysis of glial subpopulations revealed astrogliosis without activated microglia, which was associated with synaptic changes but not neurodegenerative pathology.<\/jats:p><jats:p><jats:bold>Discussion:<\/jats:bold> These results indicate that the pulvinar, a region with relatively low Lewy body pathological burden, manifests changes at the molecular level that differ from previous reports in a more severely affected region. We speculate that these alterations result from neurodegenerative changes in regions connected to the pulvinar and likely contribute to a variety of cognitive changes resulting from decreased cortical synchrony in dementia with Lewy bodies. \u00a9 2018 International Parkinson and Movement Disorder
