Further analysis of the relationship between PDIA3 and tumor immune cell infiltration showed that PDIA3 expression was related to immune cell infiltration in most types of tumors, especially immune cells such as B cell memory, plasma cells, CD4 naive T cells, memory resting T cells CD4, Tregs, activated NK cell, M1 macrophages, macrophages, and mast cells. Here, PDIA3 is linked to neoplasm.
