High‐risk microbial profiles (Nitriliruptor, Blautia, and Elizabethkingia) are linked to the presence of memory B cells, while low‐risk profiles (Nitrobacter, Flectobacillus, and Limnohabitans) show increased proportions of activated B cells, dendritic cells (DCs), macrophage cells (MQs) and CD8+ T cells, highlighting their potential prognostic value in endometrial cancer (Figure 4c).81, 82, 83. Here, CD8A is linked to endometrial cancer.
