To further understand the correlation between COL11A1 and breast cancer immune status, we analyzed the correlation of COL11A1 expression with immune infiltration of various functional T cell subtypes, and the results showed that COL11A1 expression was correlated with 29 markers, which were expressed in Th1, Th1-like cells, Th2 cells, Treg cells, resting Tregs, effector Treg cells, naive T cells, effector memory T cells, resistant memory T cells and exhausted T cells (Supplementary Table S2). Here, COL11A1 is linked to breast cancer.
