The findings revealed that GC patients demonstrated greater enrichment levels of naïve B cells, naïve CD4 T cells, activated memory CD4 T cells, follicular helper T cells, activated NK cells, M0 Macrophages, M1 Macrophages, and Neutrophils (Figure 1F), indicating that variations in the immunological status could serve a critical role in the progression of GC. Here, CD4 is linked to gastric cancer.
