Representative formalin-fixed paraffin embedded autopsy liver tissue from HIV- (a-d) and HIV+ (e-h) cases stained with hematoxylin and eosin (a-b, e-f) or Masson’s trichrome stain (c-d, g-h). A minority of HIV+ and HIV- cases were histologically unremarkable (a, c, e, g), while several HIV+ and HIV- cases exhibited moderate to severe micro- and macrovesicular steatosis (b, f) and/or severe fibrosis/cirrhosis (d, h). Original magnification 40× (c-d, g-h) or 400× (a-b, e-f). Brain and liver pathology, amyloid deposition, and interferon responses among older HIV-positive patients in the late HAART era: BMC Infectious Diseases. Not altered. CC.
