CEBPB and Alzheimer disease: To test whether inoculation of AD patients’ feces affects the enteric neurons that express C/EBPβ in the Thy-1-C/EBPβ mouse, we performed p-C/EBPβ/Aβ42 and p-C/EBPβ/AT8 co-IF on the enteric neurons in the gut sections and found that the enteric neurons were also influenced by the AD patients’ feces as CNS neurons in the brain (Supplementary Fig 14).
