Neutrophil depletion impairs natural killer cell maturation, function, and homeostasis
Natural killer (NK) cells are bone marrow (BM)-derived granular lymphocytes involved in immune defense against microbial infections and tumors. In an N-ethyl N-nitrosourea (ENU) mutagenesis strategy, we identified a mouse mutant with impaired NK cell reactivity both in vitro and in vivo. Dissection of this phenotype showed that mature neutrophils were required both in the BM and in the peripher...
متن کاملDeciphering the killer‐cell immunoglobulin‐like receptor system at super‐resolution for natural killer and T‐cell biology
Killer-cell immunoglobulin-like receptors (KIRs) are components of two fundamental biological systems essential for human health and survival. First, they contribute to host immune responses, both innate and adaptive, through their expression by natural killer cells and T cells. Second, KIR play a key role in regulating placentation, and hence reproductive success. Analogous to the diversity of...
متن کاملDeciphering the biology of NKG2C+ natural killer cells
The classic division of the immune system into an innate and an adaptive branch has been one of the dominant paradigms for immunologists shaping both questions and interpretations in the field for many years. This traditional concept has been challenged recently and the once clear boundaries are beginning to blur. Exciting new findings demonstrate that during the course of an immune response, N...
متن کاملNatural killer cell deficiency.
Natural killer (NK) cells are part of the innate immune defense against infection and cancer and are especially useful in combating certain viral pathogens. The utility of NK cells in human health has been underscored by a growing number of persons who are deficient in NK cells and/or their functions. This can be in the context of a broader genetically defined congenital immunodeficiency, of wh...
متن کاملNatural killer cell neoplasms.
Lymphoid neoplasms that are derived from natural killer (NK) cells are uncommon but distinct clinicopathologic disease entities. Three types have been recognized and categorized in the latest World Health Organization classification: extranodal NK cell lymphoma, nasal-type; aggressive NK cell leukemia; and blastic NK cell lymphoma. All NK tumor cells express the NK cell marker CD56, but they la...
