Abstract
Regulation of immune cell function is an important in the field of hormone-related tissue engineering and regenerative medicine. In this sense, hormonal regulation of immune cell function is a critical issue to be solved. It has been known that ovarian sex hormone play an important roles in immune function, however, little has been known whether estrogen affects T-lymphocyte function. Human Jurkat T cells were treated with estradiol (E2) at concentrations of 0, 10, 100, 1000 ng/mL, and calcium response was evaluated. Intracellular calcium concentrations after Fura-2 acetoxymethyl ester treatment show an increasing trend at higher E2 concentrations although these alterations did not reach a statistical significance. The expression of calcium channel-related gene CACNA1C did not show any significant changes according to the concentration of E2. Taken together, estrogen has an implication as a possible hormonal regulator of intracellular calcium release in human Jurkat T cells via non-genomic pathway. Further studies are necessary to investigate the combined effects of sex hormones and cytokines in both T- and B-lymphocytes.
