CD4 and colorectal cancer: We discovered that CD4 memory resting T Cells and resting dendritic cells were significantly associated with the low risk group, while in a related study on colorectal cancer, the low risk group had a higher percentage of CD4 memory resting T Cells, activated dendritic cells, and resting dendritic cell infiltration, as compared to the high-risk group (Li et al., 2020).
