Project: Delivery of CRISPR Ribonucleoproteins to Airway Epithelia Using Novel Amphiphilic Peptides
The proposed research is relevant to the public health because genetic and acquired diseases affecting the airways pose major disease and economic burdens. By advancing the delivery of gene editing tools, it may be possible to therapeutically modify the cells lining the airways. This novel strategy has implications for the treatment of both monogenetic and acquired lungs disease, and may have applications for other somatic cell therapies.

Gene editing in vitro by various peptide variants delivering Cas12a in NK cells. |
In Vitro | In Vitro shuttle peptide delivery of Cas12a RNP targeting human NKG2A gene in human NK cells. Gene editing was assessed after 48hr by T7E1 digestion. | ||||

Gene editing in vitro by various peptide variants delivering Cas RNPs to primary Human airway epithelia cells. |
In Vitro | In Vitro shuttle peptide delivery of Cas12a RNPs targeting human CFTR and HPRT genes in human primary airway epithelia. Editing efficiency was assessed after 72hrs by sanger sequencing. | ||||

Shuttle peptides enable in vivo gene editing with Cas9 and Cas12a RNP in mouse airway epithelia |
In Vivo | In vivo shuttle peptide delivery of Cas9 and Cas12a RNPs in mouse airway epithelia. Gene editing was quantified by the GFP+ cells in large and small airways following 1 delivery of GFP protein by GFP positive cells compared to DAPI stained cells. | ||||
