Heterogeneity of Intratumoral Microbiota Within the Tumor Microenvironment and Relationship to Tumor Development

open access: yesMed Research, EarlyView.
Mutual shaping of tumor microbiota and TME. Intratumoral microbiota—comprising diverse bacteria, fungi, viruses, and intracellular organisms—play critical and dynamic roles in shaping the tumor microenvironment (TME). Their spatial and compositional diversity contributes to both intratumoral and intertumoral heterogeneity, influencing immune modulation
