Fig. 2From: Cytomegalovirus cell tropism and clinicopathological characteristics in gastrointestinal tract of patients with HIV/AIDSExpression of PDGFRα and Nrp2 in different sites of the gastrointestinal tract in patients with HIV/AIDS and CMV. (A) Expression level of PDGFRα on mesenchymal cells was higher than epithelial cells in colon. IHC, original magnification 200×. (B) Expression of Nrp2 on hyperplastic mesenchymal cells in areas with ulcers in colon. IHC, original magnification 200×. (C) Expression level of Nrp2 on epithelial cells was higher than mesenchymal cells in duodenum. IHC, original magnification 200×. (D) Expression level of PDGFRα on epithelial cells and mesenchymal cells was similarly in the gastric antrum. IHC, original magnification 200 ×Back to article page
