Quantitation of HIV-1p24-expressing cells in NP-IDV-BMM-treated HIV-1-infected hu-PBL-NOD/SCID mice. (A) Numbers of human PBLs in cervical lymph nodes (C-LN), M-LN, spleen, liver, and lung were determined from Vim⁺ immunostained sections. (B) Numbers of HIV-1p24⁺ cells were normalized to total Vim⁺ cells and expressed as the mean percent (± SEM). ^*P < .05 and ^**P < .01 compared with untreated controls.
