Analysis of tumor-immune infiltrations in PAC by TIMER showed that infiltration levels of macrophages, monocytes, myeloid dendritic cells (mDC), CD4 + T cells, CD8 + T cells, natural killer cells and memory B cells were positively correlated with LGI3 expression significantly (Fig. 8A, B, C, E, F, G, and H). The gene discussed is CD8A; the disease is neoplasm.
