Fig. 3From: Low Copy Number and Limited Variability of Proviral DNA in Alveolar Macrophages from HIV-1-Infected Patients: Evidence for Genetic Differences in HIV-1 between Lung and Blood Macrophage Populations Intrapatient nucleotide similarity histogram in HIV-1 envelope sequence (V3–V5, 597–654 bp) from five HIV + patients (A) Intrapatient similarity of sequences in monocytes (PBM, n = 94). (B) Intrapatient similarity of sequences in alveolar macrophages (AM, n = 107). (C) Intrapatient similarity of sequences between monocytes and alveolar macrophages (PBM-AM, n = 223). Each sequence within a set was compared with every other sequence in that set.Back to article page
