BACKGROUND Dual/mixed-tropic HIV-1 strains are predominant in a significant proportion of patients, though little information is available regarding their replication-capacity and susceptibility against CCR5-antagonists in-vitro. The aim of the study was to analyze the replication-capacity and susceptibility to maraviroc of HIV-1 clinical isolates with different tropism characteristics in prima...
We molecularly cloned and analyzed an N-tropic ecotropic retrovirus induced with iododeoxyuridine from RFM/Un mouse cell cultures. Based on the restriction map, the RFM/Un virus appears to be indistinguishable from other induced N-tropic retroviruses. A nucleotide sequence analysis of the long terminal repeat of an infectious clone revealed structural features characteristic of murine type C re...
We assessed the quantitative performances of a classical method for profiling urinary organic acids: ethyl acetate extraction/oxime-trimethylsilyl derivatization/GC-MS. Twenty-seven acids were quantified on the basis of specific ions in both scan and selected-ion monitoring modes. We found that the tuning of the mass detector severely affects the calibration factors, being critical to achieve q...
Innate responses during acute HIV infection correlate with disease progression and pathogenesis. However, limited information is available about the events occurring first hours of in mucosal sites transmission. With an ex vivo HIV-1 challenge model human colorectal tissue we assessed induced by R5- X4-tropic isolates 24 h exposure. Microscopy studies demonstrated virus penetration up to 39 μm ...
