Objectives
Narrative objectives1
In this study, we clarify the function of Alpha-2-glycoprotein 1, zinc-binding (ZAG) as a tumor immunoregulatory mechanism via androgen receptor (AR) signal in breast cancer.
Basic objectives2
Others
Basic objectives -Others
Single cell suspension is prepared from the tumor tissue collected from the primary breast cancer excision sample, and the sample is evaluated by multicolor flow cytometry and flow bead array to perform phenotypic analysis of intratumoral immune cells and cytokine quantification. Subsequently, AR, ZAG, AR, PD-L1 expression and tumor infiltrating immune cells (TILs) are evaluated by immunostaining in the same specimen. The correlation between ZAG, intratumoral immune cell composition, cytokine composition, expression of various immune checkpoint-related molecules, and TILs are analyzed.
The action of recombinant ZAG on primary immune cells or model cell lines, corresponding to immune cells considered to be the primary target of ZAG will be clarified by in-vtro study.

Results
This study analyzed immunological characteristics of the breast cancer tumor microenvironment. Tumor-infiltrating lymphocytes (TILs) and PD-L1 expression were associated with immune status and distinct immune cell compositions. Hormone receptor expression (ER, PgR, AR) was linked to reduced immune cell infiltration. AZGP1/ZAG expression correlated with immune-related processes and macrophage infiltration and influenced macrophage differentiation and polarization.
