  • In Vivo CRISPR Gene Editing in Patients with Herpes Stromal Keratitis. Molecular therapy : the journal of the American Society of Gene Therapy Wei, A., Yin, D., Zhai, Z., Ling, S., Le, H., Tian, L., Xu, J., Paludan, S. R., Cai, Y., Hong, J. 2023


    In vivo CRISPR gene therapy holds large clinical potential, but the safety and efficacy remain largely unknown. Here, we injected a single dose of HSV-1-targeting CRISPR formulation in the cornea of three patients with severe refractory herpes stromal keratitis (HSK) during corneal transplantation. Our study is an investigated initiated, open-label, single-arm, non-randomized interventional trial at a single center (NCT04560790). We found neither detectable CRISPR-induced off-target cleavages by GUIDE-seq nor systemic adverse events for 18 months on average in all three patients. The HSV-1 remained undetectable during the study. Our preliminary clinical results suggest that in vivo gene editing targeting the HSV-1 genome holds acceptable safety as a potential therapy for HSK.

  • Targeting herpes simplex virus with CRISPR-Cas9 cures herpetic stromal keratitis in mice NATURE BIOTECHNOLOGY Yin, D., Ling, S., Wang, D., Dai, Y., Jiang, H., Zhou, X., Paludan, S. R., Hong, J., Cai, Y. 2021; 39 (5): 567-577


    Herpes simplex virus type 1 (HSV-1) is a leading cause of infectious blindness. Current treatments for HSV-1 do not eliminate the virus from the site of infection or latent reservoirs in the trigeminal ganglia. Here, we target HSV-1 genomes directly using mRNA-carrying lentiviral particles that simultaneously deliver SpCas9 mRNA and viral-gene-targeting guide RNAs (designated HSV-1-erasing lentiviral particles, termed HELP). We show that HELP efficiently blocks HSV-1 replication and the occurrence of herpetic stromal keratitis (HSK) in three different infection models. HELP was capable of eliminating the viral reservoir via retrograde transport from corneas to trigeminal ganglia. Additionally, HELP inhibited viral replication in human-derived corneas without causing off-target effects, as determined by whole-genome sequencing. These results support the potential clinical utility of HELP for treating refractory HSK.

  • The Inactivated gE/TK Gene-Deleted Vaccine Against Pseudorabies Virus Type II Confers Effective Protection in Mice and Pigs FRONTIERS IN MICROBIOLOGY Jin, Y., Yin, D., Xing, G., Huang, Y., Fan, C., Fan, C., Qiu, X., Dong, W., Yan, Y., Gu, J., Zhou, J. 2022; 13: 943707


    The highly virulent and antigenic variant of Pseudorabies virus (PRV) that emerged from classical Bartha-K61-vaccinated pig herds has caused substantial economic losses to the swine industry in China since 2011. A safe and more effective vaccine is most desirable. In this study, a gE/TK gene-deficient PRV, namely, HD/c, was constructed based on a PRV type II DX strain isolated from a commercial vaccine-immunized farm and the HD/c-based inactivated vaccine was formulated and evaluated for its safety, immunogenicity, and protective efficacy in mice and piglets. The resulting PRV HD/c strain has a similar growth curve to the parental DX strain. After vaccination, the inactivated HD/c vaccine did not cause any visible gross pathological or histopathological changes in the tissues of mice and piglets and provided rapid and potent protection against the challenge of the classical and variant PRVs at day 21 post-vaccination in mice. A single immunization of 108.5TCID50 inactivated PRV HD/c strain-elicited robust immunity with high titer of neutralizing antibody and provided complete protection from the lethal challenge of PRV DX strain in piglets. These results indicated that the inactivated PRV HD/c vaccine with the deletion of gE/TK genes was a safe and effective PRV vaccine candidate for the control of PRV.

  • Lentiviral delivery of co-packaged Cas9 mRNA and a Vegfa-targeting guide RNA prevents wet age-related macular degeneration in mice NATURE BIOMEDICAL ENGINEERING Ling, S., Yang, S., Hu, X., Yin, D., Dai, Y., Qian, X., Wang, D., Pan, X., Hong, J., Sun, X., Yang, H., Paludan, S., Cai, Y. 2021; 5 (2): 144-156


    Therapeutic genome editing requires effective and targeted delivery methods. The delivery of Cas9 mRNA using adeno-associated viruses has led to potent in vivo therapeutic efficacy, but can cause sustained Cas9 expression, anti-Cas9 immune responses and off-target edits. Lentiviral vectors have been engineered to deliver nucleases that are expressed transiently, but in vivo evidence of their biomedical efficacy is lacking. Here, we show that the lentiviral codelivery of Streptococcus pyogenes Cas9 mRNA and expression cassettes that encode a guide RNA that targets vascular endothelial growth factor A (Vegfa) is efficacious in a mouse model of wet age-related macular degeneration induced by Vegfa. A single subretinal injection of engineered lentiviruses knocked out 44% of Vegfa in retinal pigment epithelium and reduced the area of choroidal neovascularization by 63% without inducing off-target edits or anti-Cas9 immune responses. Engineered lentiviruses for the transient expression of nucleases may form the basis of new treatments for retinal neovascular diseases.
