Journal ArticleDOI

Abnormal Development of Intestinal Intraepithelial Lymphocytes and Peripheral Natural Killer Cells in Mice Lacking the IL-2 Receptor β Chain

TL;DR: The dependence of NK cells and certain subclasses of IEL cells on IL-2Rβ expression points to an essential role for signaling through this receptor, presumably byIL-2 and/or IL-15, in the development of lymphocyte subsets of extrathymic origin.
Journal ArticleDOI

Essential roles of CD8+CD122+ regulatory T cells in the maintenance of T cell homeostasis.

TL;DR: It is shown that the transfer of CD8+CD122+ cells into CD122-deficient neonates totally prevented the development of abnormal T cells, and this results indicate that the CD8 + CD122+ population includes naturally occurringCD8+ regulatory T cells that control potentially dangerous T cells.
Journal ArticleDOI

Cutting Edge: CD8+CD122+ Regulatory T Cells Produce IL-10 to Suppress IFN-γ Production and Proliferation of CD8+ T Cells

TL;DR: Investigation of the effector mechanism of CD8+CD122+ regulatory T cells by using an in vitro regulation system indicates that IL-10 is produced by CD8- CD122+ cells and mediates the regulatory activity of these cells.
Journal ArticleDOI

4-hydroxynonenal induces a cellular redox status-related activation of the caspase cascade for apoptotic cell death.

TL;DR: It is demonstrated that HNE triggers oxidative stress-linked apoptotic cell death through activation of the caspase cascade, and a possible mechanism involving a direct scavenge of intracellular GSH by HNE is suggested.
