Spatiotemporal Immune Landscape of Colorectal Cancer Liver Metastasis at Single-Cell Level

🤖 Plain-English Summary

Abstract Liver metastasis, the leading cause of colorectal cancer mortality, exhibits a highly heterogeneous and suppressive immune microenvironment. Efficient neoadjuvant chemotherapy can slow down such metabolic activation, raising the possibility to target metabolism pathways in metastasis.

🔑 Key Findings

• Here, we sequenced 97 matched samples by using single-cell RNA sequencing and spatial transcriptomics.
• Strikingly, the metastatic microenvironment underwent remarkable spatial reprogramming of immunosuppressive cells such as MRC1+ CCL18+ M2-like macrophages.
• We further developed scMetabolism, a computational pipeline for quantifying single-cell metabolism, and observed that those macrophages harbored enhanced metabolic activity.
