To further verify the localization of p38α and γ in control and DLB brains, we performed immunofluorescence and confocal analysis of neocortical sections double labeled with antibodies against p38α or γ and pre-synaptic (synaptophysin), neuronal (NeuN), astroglial (GFAP), or Lewy body (α-syn, syn-1) markers (Supplementary Figure S1). This evidence concerns the gene SYN1 and Lewy body dementia.
