Abstract

Background: This study investigates the role of S100A11 as a potential biomarker for glioma-associated macrophages (GAMs) and its correlation with GAMs infiltration in glioblastoma multiforme, aiming to better understand the immune microenvironment of glioma.

Methods: We conducted a comprehensive study using various techniques and approaches. First, we examined the expression of S100A11 on GAMs through Western blot, immunohistochemistry, and immunofluorescence analyses. Additionally, we utilized single-cell sequencing data and immune infiltration analysis to establish the relationship between S100A11 and GAMs infiltration in glioma.

Results: Our findings revealed that S100A11 was highly expressed on GAMs, as validated by Western blot, immunohistochemistry, and immunofluorescence. Moreover, S100A11 exhibited a strong correlation with GAMs infiltration, as evidenced by single-cell data and immune infiltration analysis. These results highlight the significant association of S100A11 with the immune microenvironment surrounding glioma.

Conclusion: S100A11 emerges as a promising candidate for regulating glioma immunosuppression and may serve as a potential marker for GAMs. This study sheds light on the crucial role of S100A11 in the crosstalk between GAMs and glioma cells, contributing to our understanding of glioma progression within the tumor microenvironment.
