Figure 2. Immunohistochemistry experiments were used to compare symptomatic carotid plaques (SC) and asymptomatic carotid plaques (AsC).

Asymptomatic lesions presented higher OPG infltration, p<0.001 (A), higher CD146⁺ pericyte infiltration, p<0.001 (B), and higher CD31⁺ endothelial cell infiltration, p = 0.23 (C). Representative images are on the left with corresponding quantification on the right.
