Abstract

Hydrogen peroxide (H2O2) is well known as a cell damaging agent that is produced during normal cell metabolism of aerobic organisms. An excessive production of oxygen metabolites such as H 2O2 leads to oxidative stress and disease. On the other hand, it recently was discovered that H2O2 is not only a deleterious oxidant for cells but can also play an important role as a beneficial signaling molecule in certain cells such as T lymphocytes. T lymphocytes are major regulatory cells in the inflammatory cascade and can act by releasing either toxins or beneficial signaling molecules. Understanding how to regulate the actions of H2O2 in T cells will allow for the creation of novel ways to improve the treatment of inflammatory diseases. The current study presents baseline information on the effects of H 2O2 on Jurkat cells, a T cell line list we use as a T cell model for therapeutic research. We first determined the half-life of 0-80 μmolar H2O2 added to Jurkat cultures using a real-time H2O2 monitoring system. We then exposed Jurkat cells to such H2O2 concentrations and found that 50±10 μmolar H2O2 promoted interleukin-2 production in cells activated with anti-CD3 at the T cell receptor plus phorbol myristate acetate as a co-stimulatory signal. These effects were not seen in non-activated, normal Jurkat cells, where H2O2 inhibited cell proliferation and induced apoptosis in a dose-dependent way without affecting interleukin-2 production. Our data indicate that Jurkat cells can model both healthy and inflammatory T cells that respond differently to oxidative metabolites such as H2O2.
