Single-cell and spatial transcriptomics reveal that the CXCL12-CXCR4 axis drives the immune-desert phenotype in small cell lung cancer by recruiting immunosuppressive CXCR4+ neutrophils and S100A8+ monocytes

Journal for ImmunoTherapy of Cancer | |

Background <p>Small cell lung cancer (SCLC) is a recalcitrant malignancy with limited responses to immunotherapy, largely due to its uniquely immunosuppressive tumor microenvironment (TME). However, the molecular mechanisms driving this phenotype remain incompletely understood.</p> Methods <p>We integrated single-cell RNA sequencing and Xenium in situ spatial transcriptomics to analyze the immune microenvironment of five SCLC and four non-small cell lung cancer…
