Abstract
Transferrin is an iron carrier protein involved in iron uptake and the regulation of cell growth. Although highly proliferative cells express transferrin and its receptor, little is known about the role of transferrin in the cellular response to cytokine production. The non-iron-bound form of transferrin (apo-transferrin) was administered to human chronic myeloid leukemia cell line, K-562 cells to assess whether it could induce interleukin-18 (IL-18). Apo-transferrin enhanced IL-18 mRNA and protein and, moreover, IL-18 secretion was increased by treatment with apo-transferrin. In conclusion, apo-transferrin regulates IL-18 expression and we suggest that it is involved in cytokine production.
