• infection
  • This is an open-label (all people know the identity of the intervention), multi-center (study conducted at multiple sites), uncontrolled (all the patients receiving darunavir) clinical and observational study (study in which the investigators/physicians observe the patients and measure their outcomes) to evaluate the safety and effectiveness of darunavir for the treatment human immunodeficiency virus-type 1 (HIV-1) infection among adult Filipino patients. (clinicaltrials.gov)
  • Conceivably, comparative studies on immune responsiveness of the HIV-1 and HIV-2 infected hosts may help to explain differences in pathogenesis and transmission between the two types of infection. (lu.se)
  • Previous studies have shown that the neutralizing antibody response is more potent and broader in HIV-2 than HIV-1 infection. (lu.se)
  • Using the area-under-curve (AUC)-based readout, multivariate statistical analysis confirmed that type of HIV infection was independently associated with the magnitude of the C' effect. (lu.se)
  • In summary, these findings suggest that antibody binding to HIV-2 structures facilitates efficient use of C', and may thereby be one factor contributing to a strong antiviral activity present in HIV-2 infection. (lu.se)
  • Viral
  • To evaluate, in HIV-infected patients whose baseline CD4 count is 300 to 750 cells/mm3, whether an antiretroviral treatment regimen based upon clinical evaluation and CD4 counts plus HIV RNA viral load is more effective than a treatment regimen based upon clinical evaluation and CD4 counts without the use of HIV RNA viral load information. (clinicaltrials.gov)
  • It is hypothesized that among HIV-infected patients whose baseline CD4 count is in the range of 300 to 750 cells/mm3, those patients who incorporate initial and periodic viral RNA measurements in their therapeutic decisions will have higher CD4 counts after 48 weeks than patients whose therapeutic decisions do not incorporate initial and periodic viral RNA measurements. (clinicaltrials.gov)
  • study
  • In the present study we have further examined the function of the humoral immune response and studied the potentiating effect of complement (C') on antiviral activity of plasma from singly HIV-1 or HIV-2 infected, as well as HIV-1/HIV-2. (lu.se)
  • cells
  • We investigated the distribution of GM1-rich lipid rafts in HIV-1-infected (effector) T cells and observed Env colocalization with polarized raft markers GM1 and CD59 but not with the transferrin receptor that is excluded from lipid rafts. (ox.ac.uk)
  • Neutralization and antibody-dependent complement-mediated inactivation of HIV-1 and HIV-2 isolates were tested in a plaque reduction assay using U87.CD4-CCR5 cells. (lu.se)
