Ravi Agrawal: Next step would be to get stem cells from a person. And then just do gene editing, he says. But we've got the tools now to genetically engineer the sort of changes into a person's cells and make it as though they were naturally a carrier of this CCR5 Delta 32 mutation that gives you resistance to HIV. So there's some way to go, but it's exciting all the same, isn't it? Absolutely very exciting for me. Thank you, Ravi.
