The invention discloses application of hydroxychloroquine to improvement of gene editing efficiency. The invention provides novel application of hydroxychloroquine, namely application of hydroxychloroquine in improving gene editing efficiency of a gene editing reagent on a receptor biological material. In the prior art, a research of combining hydroxychloroquine and gene editing efficiency is not seen. The inventor of the invention finds that the gene editing efficiency can be remarkably improved by treating a receptor biological material with hydroxychloroquine and then transfecting a gene editing reagent. The method is easy and convenient to operate and wide in applicability, and a new way for improving the editing efficiency is developed by introducing exogenous small molecules instead of directly modifying a gene editing tool. The invention provides a basis for exploring an editing efficiency improvement strategy by adding exogenous molecules instead of modifying an editor mutant.

The present application relates to the technical field of medicine, and particularly discloses application of chiral hydroxychloroquine or a pharmaceutically acceptable salt thereof in preparation of a drug for preventing and treating immune diseases. The chiral hydroxychloroquine or the pharmaceutically acceptable salt thereof has a better inhibition rate and a lower cell survival rate on pathological cell proliferation caused by immune diseases, including but not limited to fibroblast-like synoviocytes; the chiral hydroxychloroquine or the salt thereof combined with methotrexate / ilaris (including but not limited to) can reduce the toxic side effects on normal cells and the cell survival rate, and has a better treatment effect on immune diseases.

This invention provides methods for treating acute respiratory distress syndrome (ARDS), including ARDS associated with respiratory viral infections. [Solution] Administer plasma kallikrein (pKal) inhibitors such as anti-pKal antibodies as inhibitors of the contact activation pathway. Immunomodulators such as IL-6R inhibitors, antiviral agents such as lopinavir, ritonavir, interferon beta, umfenovir, and remdesivir, antimalarial agents such as chloroquine, and / or inhibitors of the contact activation pathway such as C1 inhibitors, pKal inhibitors, and bradykinin receptor antagonists may be administered to the patient as additional therapeutic agents.

AAV vectors are ideally suited for long-term delivery of a combination of broadly neutralizing antibodies to achieve sterilizing immunity to HIV. Unfortunately, host immune responses to the delivered antibody have severely limited the efficacy. The TLR9 pathway has been identified in initiating adaptive immune responses against AAV and delivered bNAbs. To enhance this strategy, we validated Hydroxychloroquine, a known drug inhibitor of the TLR9 pathway, as a pretreatment to AAV delivery to avoid anti-drug antibody responses. TLR9 signaling inhibition was validated using a HEK-Blue hTLR9 reporter cell line and CpG stimulation. Hydroxychloroquine was also validated in a 3-macaque trial where AAV9-3BNC117 and AAV9-10-1074 were administered along with 3 doses of hydroxychloroquine once a week starting 1 week before AAV inoculation. Together, these data suggest that the short-term treatment of hydroxychloroquine at the time of AAV inoculation has a meaningful impact on tolerance induction to our AAV-delivered bNAbs.
