PLP1 and atherosclerosis: Neuron significantly expressed Plp1 and Egf18. In addition, pericytes were defined by the presence of Notch3. Epithelial cells were confirmed by the specific expression of Upk3b and Cadm4. Both pericytes (Juchem et al., 2010) and epithelial cells (Wilhelmson et al., 2018) had been reported in the pathological process of atherosclerosis.
