Enriched LPS Staining within the Germinal Center of a Lymph Node from an HIV-Infected Long-Term Nonprogressor but Not from Progressors

Figure 2

Identification of collagen I staining in lymph nodes of two HIV-negative donors, three ART-naïve chronically HIV-infected progressors, and one chronically HIV-infected LTNP. Representative images of unselected LN sections stained for collagen I antigen (red, 200x and 400x). The HIV+ progressors showed increased collagen I staining in LNs; the LTNP and HIV-negative donors showed decreased collagen I staining in the LNs compared to HIV+ progressors.
