Not much is known about the role of EDI3 in different immune cell populations, but databases, such as the Human Protein Atlas web-based resource (https://www.proteinatlas.org/) indicate that EDI3 expression is elevated in several types of immune cells, in particular macrophages, as well as in T and B/plasma cells, which are known to be associated with better prognosis in breast cancer [65]. Here, GPCPD1 is linked to breast cancer.
