Current treatment of cervical cancer involves radical hysterectomy, radiotherapy, and chemotherapy or a combination.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>We investigated if hapten-enhanced intratumoral chemotherapy (HEIC) was effective in boosting immunity for effective treatment of precancerous cervical lesions and HPV infection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study design<\/jats:title><jats:p>We used single-cell RNA sequencing (scRNA-Seq) to obtain transcriptome profiles of 40,239 cells from biopsies of precancerous cervical lesions from the cervix directly from one patient before the start of HEIC and approximately 1 week after HEIC. The blood samples were taken at the same time as biopsies. We compared the expression characteristics of malignant epithelial cells and immune cells, including epithelial cells, endothelial cells (ECs), fibroblasts, mural cells, T cells, B cells, T and NK neutrophils, mast cells, microparticles (MPs), and platelets, as well as the dynamic changes in cell percentage and cell subtype
