Given that the tumor immune microenvironment (TIM) plays an important role in the progress and metastasis of cancers, we evaluated the correlations of CEMIP expression with several immune cell infiltration levels in various types of cancers, consisting of CD8+ T cells, CD4+ T cells, B cells, macrophages, neutrophils, DC, NK cells, and CAF using the TIMER2.0 web with all algorithms provided. The gene discussed is CD4; the disease is cancer.
