Contrasted with low LRRC59 expression BC, the infiltration abundance of resting memory CD4 T cells, memory activated CD4 T cells, resting NK cells, macrophages M0, M1, M2, and neutrophils increased in high LRRC59 expression BC, while the infiltration abundance of plasma cells, naïve CD4 T cells and regulatory T cells (Tregs) declined in high LRRC59 expression BC (Figure 6). The gene discussed is CD4; the disease is breast cancer.
