Overall, high LHPP expression was significantly associated with altered tumor immune infiltration characteristics, showing a positive correlation with the infiltration abundance of CD3+ (Fig. S17C–E), CD4+ (Fig. S17F–H), CD45+ T cells (Fig. S17I–K), and CD8+ (Fig. S17R–T), in both the center of the tumor and the invasive margin. The gene discussed is CD4; the disease is neoplasm.
