Q2. What is the effect of anti-APO-1 on the cellular blebbing?
In addition, endonudease-mediated DNA fragmentation induced by anti-APO-1 was not inhibited by the Ca2" channel blockers Furamicin (50 FM) or Nifedipin (50 ;.M).
Q3. What is the effect of HIV-1 on the surface of the infected cells?
In vitro infection of cells with HIV-1 results in a decreased expression of the CD4 molecule on the surface of the infected cells (2).
Q4. How many days after fusion culture were the MAbs tested?
Twelve days after fusion culture supematants from wells positive for growth were tested for their ability to inhibit growth ofSKW6.4 cells.
Q5. How many cells were obtained from the CCRF-CEM subclone?
The CCRF-CEM.S2 subclone was obtained bydoning cells under limiting dilution conditions from the CCRF-CEM T cell line at one cell per well in 96- well microtiter plates.
Q6. What is the phenotypic analysis of CD3+ cells?
The phenotypic analysis of freshly sorted CD3+/CD4+ cells revealed a greater than 98 to 99% CD4+ purity in most experiments when stained with the monoclonal antibody to Leu 3a.
Q7. What is the effect of HIV-1 on the peripheral blood?
only a very small number of cells in the peripheral blood ofHIV-1-infected individuals are expressing virus at any given time.
Q8. What subpopulation of PBMCs was HIV-1 expressed in vivo?
Within PBMCs, HIV-1 was expressed in vivo predominantly in the T cell subpopulation which, in contrast to the in vitro observations, continued to express CD4.
Q9. How many CD4+ T cells were grown in the same conditions?
Phenotypic analysis of non-cocultured enriched CD4- T cells grown under the same conditions revealed that 30 to 55% of the cells were CD4+ by day 10 in culture.
Q10. What methods were used to examine the PBMCs?
They were examined with the methodologies of virus isolation by limiting dilution analysis, in situ hybridization, immunofluorescence, and gene amplification.
Q11. What is the frequency of the CD4+ T cells in AIDS patients?
T cell population contained HIV-1 DNA in all HIV1-infected individuals studied and the frequency in AIDS patients was at least 1/100 cells.
Q12. What was the frequency of the in situ hybridization for HIV-1 in the PBMCs?
Indirect immunofluorescence studies for HIV-1 viral antigens was also performed at time zero on highly enriched CD3+/CD4+and CD3+/CD4--sorted PBMCs.
Q13. Why was there a delay in the expression of HIV-1 in cells that were initially 99%?
Delayed expression of HIV-1 in cells that were initially 99% CD3- cells (Fig. 1B) was due to outgrowth of the few contaminating CD3+ cells.
Q14. How many MAbs were resuspended in 200 ml of culture?
Aliquots of 5 x 10' cells were resuspended in 200 ,ul of culture medium containing 0.1% NaN3 and different con-centrations of "LI-labeled MAbs.
Q15. What is the effect of the fluorescence-automated cell sorting?
In the present study, highly purified subpopulations of peripheral blood mononuclear cells (PBMCs) from AIDS patients were obtained and purified by fluorescence-automated cell sorting.
Q16. What is the cause of the decline of CD4+ T cells in AIDS patients?
Patients with AIDS have severe depression of the normal cell-mediated immune mechanisms that is partially attributed to the considerable depletion of CD4 lymphocytes (3).
Q17. What is the frequency of RNA synthesis in lymph nodes and peripheral blood?
Despite this, examination of cells from lymph nodes and peripheral blood from patients with AIDS and AIDS-related complex (ARC) has revealed a very low frequency of viral RNA synthesis, generally occurring in 1/100,000 to 1/10,000 of total mononuclear cells (4).
Q18. Why was the delayed expression of HIV-1 in cells that were initially 99% CD4+?
the delayed expression of HIV-1 in cells that were initially 99% CD4- (Fig. ID) was most likely due to outgrowth of a few contaminating CD4+
