- Researchers established a novel humanized mouse model using patient-derived xenografts (PDXs) to study glioblastoma (GBM), the deadliest adult brain tumor.
- The model uses immunodeficient mice reconstituted with human CD34+ hematopoietic stem cells, enabling human immune cell infiltration (e.g., T cells, NK cells, myeloid cells) into radiation-resistant PDX tumors.
- Analysis via spectral flow cytometry, immunohistochemistry, and single-cell RNA sequencing showed immune cell gene expression profiles similar to those in patients with recurrent GBM.
- The model demonstrates greater tumor diversity, including neural progenitor-like cells, and more accurately replicates the immunosuppressive tumor microenvironment compared to conventional models.
- This platform is valuable for analyzing the immune landscape of GBM and testing new treatments, particularly immunotherapies, potentially accelerating therapy development.
