Immune landscape of genetically-engineered murine models of glioma relative to human glioma by single-cell sequencing
Ontology highlight
ABSTRACT: This work lays the foundation for the intratumoral immune infiltrates of glioma patients analyzed at a single cell level with the dual purpose of establishing the relevance of a new mouse model of GBM with regard to the patient disease. The aim of this study was to determine the level of concordance between the spontaneous and implanted Qk/trp53/Pten (QPP) triple-knockout mouse GBM model and human glioma samples in regard to their immune infiltrates.We analyzed a cohort of fifteen spontaneous QPP mice, nine implanted QPP mice and 10 glioma patients histopathologically. Furthermore, we analyzed three spontaneous QPP mice, thee implanted QPP mice, and 10 glioma patients by single cell RNA sequencing. We found that the QPP model recapitulates human GBM regarding the major immune components including a predominantly myeloid cell population of monocytes, macrophages, and resting dendritic cells, with minor populations of T, B, and NK cells. In addition, the complexity of the myeloid cell populations is preserved between the QPP model and the human disease.
