Abstract:
Objective This study aims to explore the causal relationships between 731 immune cell phenotypes and cervical cancer using a two-sample Mendelian randomization(MR)analysis.Methods Utilizing results from genome-wide association study(GWAS),inverse variance weighted(IVW),MR-Egger regression,weighted median,simple mode and weighted mode were used for MR analysis,and sensitivity analysis was used for quality control of heterogeneity and horizontal pleiotropy.Results Using IVW as the primary analytical method and ensuring consistency in the direction of results across all five MR methods,we identified five immune cell phenotypes potentially causally associated with cervical cancer.Among these,relative count of central memory CD4+T cells in all CD4+T cells(CM CD4+％CD4+)(ORIVW=0.804,95％CI:0.685-0.943,PIVW=0.0074),absolute count of naive CD8 bright T cell(Naive CD8br AC)(ORIVW=0.493,95％CI:0.359-0.676,PIVW=0.000 01)and median fluorescence intensities of CD45 on immature myeloid-derived suppressor cells(CD45 on Im MDSC)(RIVW=0.746,95％CI:0.609-0.914,PIVW=0.0048)were positively associated with cervical cancer risk,while median fluorescence intensities of IgD on IgD+CD38-unswitched memory B cell(IgD on IgD+CD38-unsw mem)(RIVW=1.393,95％CI:1.148-1.690,PIVW=0.000 78)and median fluorescence intensities of CD3 on terminally differentiated CD8 bright T cell(CD3 on TD CD8br)(ORIVW=1.267,95％CI:1.082-1.483,PIVW=0.0033)were negatively associated with cervical cancer risk.Conclusion This study identifies five immune cell phenotypes closely related to cervical cancer risk through genetic analysis,providing new insights for early prevention and the development of novel immunotherapies for cervical cancer.
