We found that it can interact with CD38 on IgD+ CD24‐ cells, and then regulate the amount of CD38 on IgD+ CD24‐, thereby affecting the occurrence and development of the disease.[68] Some studies have found that CD38 on IgD+ CD24‐ cells are more associated with breast cancer, lung cancer and other diseases. This evidence concerns the gene CD24 and breast carcinoma.
