A small case-control study determined that aging HIV-infected people (median 56 years) with a good CD4 count (median 724 cells/mm (3)) and long-term viral suppression with antiretroviral therapy have CD4 and CD8 cells similar to those of a substantially older HIV-negative comparison group (median 88 years) and utterly unlike those of a younger HIV-negative group (median 27 years).
Both groups had similar concentrations of CD8 cells.
The proportion of CD4 cells normally exceeds that of CD8 cells.
But in the US study, the CD8 cells suppressed the virus without killing the healthy CD4T cells.
Overall, they found that the telomere length of CD8 cells was significantly shorter than CD4 telomere length in a group of 14 HIV-infected men, suggesting the new CD8 cells were being produced much faster than CD4 cells.
According to our results patients with more severe form of disease had the lowest number of both CD4 and CD8 cells which can be a sign of suppressed cellular immunity in these patients.
The researchers also used a new test for HIV-specific immune function--counting the proportion of virus-specific CD8 cells by using flow cytometry to measure which of the cells produce gamma interferon in response to killed virus.
Cloyd says that this finding could explain why the number of CD8 cells does not dramatically decline during HIV infection.
The new study concluded that the human immunodeficiency virus prompts CD8 cells to replicate at such a fast rate that eventually they grow too old to replicate themselves, the study found.
The results of these recent assessments, presented for the first time at the International AIDS Conference in Mexico, show that this novel product induces greater proliferation, maturation and differentiation of HIV-specific CD8 cells in vitro.
They found that the original portions of the virus degrade 400 times faster in response to CD8 cells than they would have if those cells weren't a factor - what scientists call significant "selective pressure" on the virus.
