Gene-based stem cell therapy specifically removes cell receptor that attracts HIV
Using a humanized mouse model, the researchers transplanted a small RNA molecule known as short hairpin RNA (shRNA), which induced RNA interference into human blood stem cells to inhibit the expression of CCR5 in human immune cells.
The findings provide evidence that this strategy can be an effective way to treat HIV-infected individuals, by prompting long-term and stable reduction of CCR5.
