Sample text

It is not clear whether the defects are a result of infection of monocytes, immunoregulatory T-cell imbalance, or supervening infections. For instance, the number of circulating monocytes is generally normal but may decline with advanced diseases. Similarly, defects in phagocytosis, intracellular killing, cytotoxicity, and class II MHC expression are most consistently found in patients with advanced disease. Antigen-specific proliferative responses are suppressed, and this is an early and relatively consistent feature of HIV infection.

For example, an infectious mononucleosis-like syndrome has been described in association with acute HIV-1 infection and seroconversion. CD4/CD8 ratios are generally low (because CD8 counts are elevated) whereas CD4 cell counts tend to be normal or low normal. 29 In studies comparing uninfected and infected risk group members who are asymptomatic, CD4/CD8 ratio is a much more sensitive indicator of HIV-1 infection than absolute CD4 T-cell count. Subjects with common but less severe clinical manifestations have abnormalities intermediate between those of AIDS patients and seropositive, asymptomatic risk group members.

6. Temporal serologic relationship between HIV-l antigen (p24) production and detection of HIV-specific antibodies. FIGURE host cell transcription (the process of conversion of DNA to RNA) factors stimulate a low level of early HIV-l gene expression. The first mRNA molecules that reach the cytoplasm from the nucleus are composed entirely of multiply spliced messages that code for the HIV-1 regulatory proteins. Once the tat protein is produced it elicits a strong positive effect on viral transcription.
