The Colibactin-Producing Escherichia coli alters the tumor microenvironment to immunosuppressive lipid overload facilitating colorectal cancer progression and chemoresistance.

This study shows that Colibactin-producing Escherichia coli creates an immunosuppressive lipid-rich tumor microenvironment that promotes colorectal cancer progression and chemoresistance.

Monocyte intrinsic NOD2 signalling inhibits pathogenic macrophage differentiation and its loss in inflammatory macrophages improves intestinal inflammation.

This study shows that NOD2 signaling in monocytes inhibits their conversion to pathogenic macrophages and its loss worsens intestinal inflammation.

Parvimonas micra, an oral pathobiont associated with colorectal cancer, epigenetically reprograms human primary intestinal epithelial cells

This study shows that Parvimonas micra phylotype A alters DNA methylation and gene expression in intestinal epithelial cells, potentially contributing to colorectal cancer.
