Chinese Herb may Harbour HIV Cure
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.
But the new study has shown that the chemical, TAT2, can prevent or slow this progressive telomere shortening.
"This has the potential to be either added to or possibly even replace the HAART (highly active antiretroviral therapy), which is not tolerated well by some patients and is also costly," said study co-author Rita Effros, a professor of pathology and laboratory medicine at the David Geffen School of Medicine at UCLA and member of the UCLA AIDS Institute.
The researchers tested TAT2 in several ways. First, they exposed the CD8 T-cells from HIV-infected persons to TAT2 to see if the chemical not only slowed the shortening of the telomeres but also improved the cells'' production of soluble factors called chemokines and cytokines, which had been previously shown to inhibit HIV replication. And they found that it did.
They then took blood samples from HIV-infected individuals and separated out the CD8 T-cells and the CD4 T-cells - those infected with HIV.
