Reversible Defects in Natural Killer and Memory Cd8 T Cell Lineages in Interleukin 15–Deficient Mice

TL;DR: Critical roles for IL-15 in the development of specific lymphoid lineages are revealed and the ability to rescue lymphoid defects inIL-15−/− mice by IL- 15 administration represents a powerful means by which to further elucidate the biological roles of this cytokine.
Journal ArticleDOI

Early lymphocyte expansion is severely impaired in interleukin 7 receptor-deficient mice.

TL;DR: In this paper, the role of IL-7 and its receptor during B and T cell development by generating mice genetically deficient in IL7R was examined and it was shown that the phase of thymocyte expansion occurring before the onset of T cell receptor gene rearrangement is critically dependent upon, and mediated by the high affinity receptor for IL7.
Journal ArticleDOI

RANK is essential for osteoclast and lymph node development.

TL;DR: Investigating the physiological role of the TNF receptor (TNFR) family member, RANK, revealed that RANK provides critical signals necessary for lymph node organogenesis and osteoclast differentiation.
Journal ArticleDOI

CD4+ T cells that express high levels of CD45RB induce wasting disease when transferred into congenic severe combined immunodeficient mice. Disease development is prevented by cotransfer of purified CD4+ T cells.

TL;DR: Interestingly, mice that received mixtures of whole lymph node or purified CD4+ cells with CD4-/CD45RBhi cells did not develop weight loss, indicating that the unseparatedCD4+ population contained cells that were capable of regulating the reactivity of the CD4+.
