Reduced immunohistochemical expression of CD25 epithelial staining of cervical specimens (mean ± SD) in the absence of HPV16 infection (Kruskal-Wallis = 0.03). A = all HIV, HPV and SIL are negative; B = HPV16 total; C = HPV16-negative, LG-SIL-positive; D = both HPV16 and LG-SIL are positive; E = HPV16-negative, HG-SIL-positive; F = both HPV16 and HG-SIL are positive. HPV = Human papillomavirus; HIV = Human Immunodeficiency Virus; SIL = Squamous Intraepithelial Lesion; LG-SIL = Low-grade Squamous Intraepithelial Lesion; HG-SIL = High-grade Squamous Intraepithelial Lesion.
