abstract = {The isocitrate dehydrogenase (IDH) gene is recurrently
mutated in adult diffuse gliomas. IDH-mutant gliomas are
categorized into oligodendrogliomas and astrocytomas, each
with unique pathological features. Here, we use
single-nucleus RNA and ATAC sequencing to compare the
molecular heterogeneity of these glioma subtypes. In
addition to astrocyte-like, oligodendrocyte progenitor-like,
and cycling tumor subpopulations, a tumor population
enriched for ribosomal genes and translation elongation
factors is primarily present in oligodendrogliomas.
Longitudinal analysis of astrocytomas indicates that the
proportion of tumor subpopulations remains stable in
recurrent tumors. Analysis of tumor-associated
microglia/macrophages (TAMs) reveals significant differences
between oligodendrogliomas, with astrocytomas harboring
inflammatory TAMs expressing phosphorylated STAT1, as
confirmed by immunohistochemistry. Furthermore, inferred
receptor-ligand interactions between tumor subpopulations
and TAMs may contribute to TAM state diversity. Overall, our
study sheds light on distinct tumor populations, TAM
heterogeneity, TAM-tumor interactions in IDH-mutant glioma
subtypes, and the relative stability of tumor subpopulations
in recurrent astrocytomas.},
