Resistance of naturally occurring regulatory T cells toward oxidative stress: possible link with intracellular catecholamine content and implications for cancer therapy

To the editor: We read with interest the paper by Mougiakakos and colleagues documenting the reduced sensitivity of naturally occurring regulatory T lymphocytes (Tregs) toward oxidative stress-induced cell death.[1][1] The authors show in in vitro experiments that Tregs, compared with CD4+ T cells
