BACKGROUND: Meningioma is a common central nervous system tumor that poses
serious health hazards and increases with age. However, the role of immune cells
in meningioma remains incompletely understood. METHODS: Data from genome-wide
association studies on meningioma, cyclic cytokines, and immune cells were
comprehensively analyzed. We conducted a two-step, two-sample mendelian
randomization study to investigate the causal relationship between immune cell
characteristics and meningioma. Furthermore, we examined the mediation effect of
cyclic cytokines in connecting the association of immune cells with the risk of
meningioma. RESULTS: Eighteen immune phenotypes showed significant correlations
with meningioma risk. Notably, Naive CD4-CD8- T cell %T Cell (OR: 1.380, 95% CI:
1.013-1.880, P?=?0.041) and FSC-A on Myeloid Dendritic Cell (OR: 1.177, 95% CI:
1.045-1.325, P?=?0.007) were implicated in promoting meningioma via MMP-1. The
mediation effects of MMP-1 in these two immune cells were 0.023 and 0.015, with
corresponding proportions of 7.110% and 8.981% in the mediation effect ratio.
CONCLUSION: Our study elucidated the causal relationship between immune cell
phenotypes and meningioma, pinpointing the potential role of MMP-1. These
findings provide clues for potential therapeutic targets.
