Expanding upon this groundwork, our investigation delves into the nuanced association between GTSE1 expression levels and the infiltration dynamics of six immune cell subtypes (B cells, CD4 T cells, CD8 T cells, neutrophils, macrophages, and dendritic cells) in pan‐cancer settings, thereby underscoring the correlation between the infiltration levels of disparate immune cell subtypes and GTSE1 expression, thereby furnishing novel insights into immune evasion mechanisms and anti‐tumor modalities. The gene discussed is CD8A; the disease is neoplasm.
