KLRG1+ Effector CD8+ T Cells Lose KLRG1, Differentiate into All Memory T Cell Lineages, and Convey Enhanced Protective Immunity

Immunity - 3 April 2018 - 12:00am
Herndler-Brandstetter et al. demonstrate that KLRG1+IL-7Rα+ effector CD8+ T cells downregulate KLRG1 in a Bach2-dependent manner and differentiate into long-lived circulating and tissue-resident “exKLRG1” memory cells. Developmental plasticity of KLRG1+ effector cells therefore drives functional diversity within memory T cell lineages and promotes enhanced anti-influenza and anti-tumor immunity.

Interleukin-15 Complex Treatment Protects Mice from Cerebral Malaria by Inducing Interleukin-10-Producing Natural Killer Cells

Immunity - 3 April 2018 - 12:00am
NK cells can display both pro-inflammatory and regulatory function, but their role in the pathogenesis of malaria is not fully understood. Burrack et al. demonstrate that IL-15 complex (IL-15C) therapy prevents mice from succumbing to experimental cerebral malaria (ECM). IL-15C treatment stimulates NK cells to produce IL-10, suppressing the pathogenic CD8+ T cell response during ECM.
