Differential expression of HIV-related genes. A: Parallel plot showing gene expression intensity for B-cell markers (CD19, CD79), antibody-related genes (Ig J polypeptide), and T-cell marker (CD3) in gingival (n = 7) and tonsil (n = 5) samples. B: Parallel plot showing expression levels/intensity for genes associated with HIV entrapment/transmission in the tonsil (n = 5) and gingival (n = 7) epithelium. C: Parallel plot showing gene expression intensity for the HIV receptor CD4 and co-receptors (GalCer, CXCR4, and CCR5) in the tonsil and gingival epithelium, *FDR < 10% and P < 0.05 of differential gene expression between sample groups. Immunohistochemical staining for CD19 in the tonsil (D) and CD3 (E). Immunohistochemical staining for ICAM-3 (F), for CD4 (H), and GalCer (I) in the tonsil epithelium. Immunofluorescence FcR-CD32 (red), pan-cytokeratin (green) and 4,6-diamidino-2-phenylindole (G). Arrows indicate positive staining. Original magnifications: ×20 (D–F, H, and I); ×63 (G).
