CD4 and lobular neoplasia: We performed a correlation analysis to further understand the relationship between FRGs and significantly infiltrated immune cells in LN patients and discovered that CD8+ T cells, resting memory CD4+ T cells, Regulatory T cells (Tregs), resting NK cells, monocytes, and resting mast cells were significantly correlated with these 10 differentially expressed FRGs (Fig. 3C), implying that feroptosis regulators may act as key factors in regulating immune infiltration levels.
