Given that immune cells are involved in the composition of the tumor microenvironment, which is of great significance to the prognosis of the tumor, we studied the potential connection between 9 hub RBPs and immune infiltration (purity, B cell, CD8+T cell, CD4+T cell, macrophage, neutrophil, dendritic cell) in the STS. The gene discussed is CD8A; the disease is telomere syndrome.
