Investigates the effects of targeted therapies on CD8+ T cell response in male medulloblastoma, suggesting a new path for treatment.

Explore sex-specific roles of Yap1 in SHH medulloblastoma and its implications for CD8+ T cell responses.
Conducted single-cell RNA sequencing and flow cytometry to analyze immune microenvironment.
Utilized CD276-targeting chemically self-assembled nanorings in treatment.
Performed T-cell proliferation assays to evaluate activation levels.
Yap1 deletion increased CD8+ T cells in males, enhancing anti-tumor response.
Males showed improved survival, while females had exhausted CD8+ T and more regulatory T cells.
CD276 blockade mimicked survival benefits seen with Yap1 deletion in males.

Abdelfattah et al. (2026) studied this question.
