Outline of Annual Research Achievements |
Step 1, "establish anti-HIV-1 CRISPR/Cas9", has went very well. We have developed gRNAs targeting HIV-1 regulatory genes, which inhibit replication in infected T cells. Multiplexed attack on HIV-1 tat blocks viral escape for 40 days, keeping the cells immune in long-term. Step 2, "transduce iPSC with CRISPR/Cas9", is going well. We used lentiviral transductions to insert genes into iPSC before antibiotic selection, which was successful. However, off-target screening needs to be done to determine the safety. Step 3, "to differentiate iPSC into T cells immune to HIV-1", is ongoing. We are developing a feeder-free culture system to differentiate iPSC into HSC and T cells. But, cell differentiation takes a very long time, whether CRISPR is functional remains to be seen, and delay is expected.
