FIG. 6.

Immunohistochemical localization and phenotypes of coreceptor-positive cells in the cervix of rhesus macaque 1360 (AEC with hematoxylin counterstain; magnification, ×400). Some of the representative positive cells are indicated by arrowheads. The majority of the CXCR4- and CCR3-positive cells are believed to be macrophages or dendritic cells and are located primarily in either the lamina propria or the epithelial lining. The CCR5-positive cells are located adjacent to the epithelium. A few HLA-DR-positive cells are also located below the epithelium.
