Murine MHC-Deficient Nonobese Diabetic Mice Carrying Human HLA-DQ8 Develop Severe Myocarditis and Myositis in Response to Anti-PD-1 Immune Checkpoint Inhibitor Cancer Therapy
Racine et al., Journal of Immunology. 2024.
Myocarditis has emerged as a relatively rare but often lethal autoimmune complication of checkpoint inhibitor (ICI) cancer therapy, and significant mortality is associated with this phenomenon. Investigators developed a new mouse model system that spontaneously develops myocarditis. These mice are highly susceptible to myocarditis and acute heart failure following anti-PD-1 ICI-induced treatment. Additionally, the treatment accelerates skeletal muscle myositis. The team performed characterization of cardiac and skeletal muscle T cells using histology, flow cytometry, adoptive transfers, and RNA sequencing analyses. This study sheds light on underlying immunological mechanisms in ICI myocarditis and provides the basis for further detailed analyses of diagnostic and therapeutic strategies.

Genome editing in the lung has the potential to provide long-term expression of therapeutic protein to treat lung genetic diseases. The authors illustrated that AAV5 can efficiently deliver CRISPR-Cas9 to mouse lung airways and was the first to achieve ∼20% editing efficiency in those airways. Results were confirmed through independent experiments at two different institutes. This highly efficient dual AAV platform will facilitate the study of genome editing in the lung and other tissue types. Supported by ORIP (U42OD026645).
