Using the Cellchat algorithm, we quantified the interaction weight of Plac1+/− epithelial cells with other immune cells and found that the differences in interaction weights between groups were more obvious in the CD4+ T‐cell subclusters than in other subclusters, which suggested that tumor cell‐CD4+ T subcluster interactions are closely associated with Plac1 expression (Figure 6B, Figure S10A,B, Supporting Information). The gene discussed is CD4; the disease is neoplasm.
