Background Cervical cancer (CC) is a highly heterogeneous malignancy primarily driven by persistent infection with high-risk human papillomavirus (HPV). However, comprehensive analyses of heterogeneity in the immune microenvironment, particularly its spatial heterogeneity, between HPV-positive and HPV-negative CC remain limited, despite their critical clinical significance. Methods We performed single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) sequencing on collected cervical cancer samples, integrating scRNA-seq, ST, and bulk RNA-seq to analyze distinct cell subtypes and characterize their spatial distribution. Multiplex immunofluorescence analysis was further utilized to validate HPV status-specific expression patterns. Cox regression and LASSO regression analyses were used to identify the prognostic signature on the TCGA dataset. Results Through integrative analysis, we found that HPV-positive samples demonstrated elevated proportions of CD4 + T cells and cDC2s, whereas HPV-negative samples exhibited increased CD8 + T cell infiltration. In HPV-positive CC, epithelial cells acted as primary regulators of cDC2s via the ANXA1 - FPR1/3 pathway, with cDC2s subsequently modulating CD4 + T cells and interferon-related CD8 + T cell subtypes. In contrast, HPV-negative CC featured epithelial cells predominantly influencing monocytes and macrophages, which then interacted with CD8 + T cells. Notably, the MDK - LRP1 ligand-receptor interaction emerged as a potent...
