Figure 5. Analysis of immune microenvironment of colorectal cancer. (A) The overall immune cell infiltration of CRC patients. (B) The high-SLC35A2-expression and low-SLC35A2-expression groups differed in the level of immune cell infiltration, and only one distinct immune cell was obtained: plasma cells. (C–F) Correlation analysis indicated that there was significant correlation between 4 types of immunity and SLC35A2: macrophages M1 and M2, T cell regulatory (Tregs) and plasma cells. (G) One of the most significant immune cell types was obtained: plasma cells.
