EGCG and HIV
There has been some research investigating the benefit of EGCG from green tea in the treatment of HIV infection. One study examined the molecular binding of ECGC to the CD4 receptor molecule on human lymphocytes. The CD4 receptor is the site where the HIV virus attaches to a cell before infecting it. To bind to CD4, HIV uses its own receptor gp120. The study found "clear evidence of high-affinity binding of EGCG to the CD4 molecule" and "inhibition of gp120 binding to human CD4+ T cells."  The mechanism is very similar to a new class of anti-HIV medications, the entry inhibitors. For reasons not yet understood, EGCG seems to have an inhibitory effect on other steps of the HIV lifecycle, including suppression of reverse-transcriptase concentration and decreased protease kinetics. These effects have only been observed in laboratory studies, not in HIV+ individuals. The concentrations of EGCG used in the studies could not be reached by drinking green tea. More study into EGCG and HIV is currently underway.
