If Neil Armstrong were a scientist, we’re pretty sure he would’ve said that about this breakthrough study. For the first time ever, the spread of the HIV virus was stopped in its tracks in a living animal, including in a humanized model. Kudos to Dr. Wenhui Hu and his team at LKSOM. This was done by using the gene editing technology CRISPR/Cas9. After replicating the findings from their previous proof-of-concept study, the team tested mice infected with EcoHIV (mouse equivalent to human HIV-1) and mice that were engrafted with human immune and T cells (i.e., “humanized”) then HIV-1. In both tests they were able to successfully excise and block further infection. Take that, HIV.
