Reconstitution of natural killer cell receptors influences natural killer activity and relapse rate after haploidentical transplantation of T- and B-cell depleted grafts in children

open access: yesHaematologica, 2010
Background Natural killer cells have been demonstrated to exert remarkable graft-versus-leukemia effects after haploidentical transplantation. Acquisition of both, inhibiting and activating, receptors on developing natural killer cells is an important ...

Reduced NK cell IFN-γ secretion and psychological stress are independently associated with herpes zoster. [PDF]

open access: yesPLoS ONE, 2018
The pathogenesis of herpes zoster is closely linked to reduced varicella-zoster virus-specific cell-mediated immunity. However, little is known about the interplay between natural killer cells and psychological stress in the pathogenesis of herpes zoster.

Cytokines impact natural killer cell phenotype and functionality against glioblastoma in vitro

open access: yesFrontiers in Immunology, 2023
ObjectiveNatural killer (NK) cells are a part of the innate immune system and first-line defense against cancer. Since they possess natural mechanisms to recognize and kill tumor cells, NK cells are considered as a potential option for an off-the-shelf ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Natural killer cell neoplasms [PDF]

open access: yesCancer, 2008
AbstractNatural killer (NK) cell tumors are an uncommon and heterogeneous group of disorders. The World Health Organization (WHO) classified mature NK cell neoplasms into 2 types: 1) extranodal NK cell lymphoma, nasal type and 2) aggressive NK cell leukemia. The mature NK cell tumors are prevalent in Asia and Central and South America.

Natural killer cell evolution: cellular and molecular studies on Xenopus [PDF]

open access: yes, 1996
The presence of natural killer cells at lower evolutionary levels was investigated in the amphibian Xenopus laevis. Chromium release microcytotoxicity assays revealed that fresh splenocytes from early-thymectomised Xenopus displayed significant ...

Relative expression of receptors in uterine natural killer cells compared to peripheral blood natural killer cells

open access: yesFrontiers in Immunology, 2023
One would expect maternal immune cells to attack the invading trophoblast as the placenta is semi-allogenic. However, they appear to cooperate with the trophoblast in disrupting the arterial wall which has been determined in several studies.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Characterisation and ontogeny of natural killer cells in Xenopus laevis [PDF]

open access: yes, 2002
The initial aim of the work described in this Thesis was to investigate the lymphoid organ distribution, phenotype and function of the lymphocyte population identified by candidate anti-Xenopus natural killer (NK) cell monoclonal antibodies (mAb's ...

Killer cell immunoglobulin-like receptors and their ligands : assessment of potential diagnostic and immunotherapeutic value [PDF]

open access: yes, 2014
Human natural killer (NK) cells constitute an important arm of the innate immune system, which participates in protection against viral infections and elimination of malignant diseases.
