Skin TLR7 triggering promotes accumulation of respiratory dendritic cells and natural killer cells. [PDF]

open access: yes, 2012
The TLR7 agonist imiquimod has been used successfully as adjuvant for skin treatment of virus-associated warts and basal cell carcinoma. The effects of skin TLR7 triggering on respiratory leukocyte populations are unknown.

Fasting enhances TRAIL-mediated liver natural killer cell activity via HSP70 upregulation.

open access: yesPLoS ONE, 2014
Acute starvation, which is frequently observed in clinical practice, sometimes augments the cytolytic activity of natural killer cells against neoplastic cells. In this study, we investigated the molecular mechanisms underlying the enhancement of natural

Functional invariant natural killer T-cell and CD1d axis in chronic lymphocytic leukemia: implications for immunotherapy

open access: yesHaematologica, 2013
Invariant natural killer T cells recognize glycolipid antigens such as α-galactosylceramide presented by CD1d. In preclinical models of B-cell malignancies, α-galactosylceramide is an adjuvant to tumor vaccination, enhancing tumor-specific T-cell ...

Natural killer cell-mediated immunopathology in recurrent pregnancy losses

open access: yesExploration of Immunology, 2022
Natural killer (NK) cells have a dual role in human reproduction for maternal-fetal tolerance and protection from infection. During the ovarian cycle and pregnancy, peripheral NK (pNK) and uterine NK (uNK) cells dynamically change their proportions and ...

Highly activated and expanded natural killer cells for multiple myeloma immunotherapy

open access: yesHaematologica, 2012
Background Patients with gene expression profiling-defined high-risk myeloma in relapse have poor outcomes with current therapies. We tested whether natural killer cells expanded by co-culture with K562 cells transfected with 41BBL and membrane-bound ...

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.

The role of natural killer cells in adaptive immune responses [PDF]

open access: yes
Human natural killer (NK) cells have been shown to respond to numerous pathogenic stimuli, producing IFN-y as well as cytolytic effector molecules such as perforin and granzymes.

Tumor recognition by natural killer cells in acute myeloid leukemia and after hematopoietic stem cell transplantation [PDF]

open access: yes, 2005
Natural killer (NK) cell-mediated cytolytic activity against tumors requires the engagement of activating NK cell receptors by the tumor-associated ligands.

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.

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 ...
