Invariant NKT cells contribute to chronic lymphocytic leukemia surveillance and prognosis [PDF]

open access: yes, 2017
Chronic lymphocytic leukemia (CLL) is characterized by the expansion of malignant CD5(+) B lymphocytes in blood, bone marrow and lymphoid organs. CD1d-restricted invariant Natural Killer T (iNKT) cells are innate-like T lymphocytes strongly implicated in

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 ...

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.

Occurrence and a possible mechanism of penetration of natural killer cells into k562 target cells during the cytotoxic interaction [PDF]

open access: yes, 1995
The cytotoxic interaction between cloned human Natural Killer (NK) cells and K562 target cells was studied using confocal laser scanning microscopy (CLSM) and conventional fluorescence microscopy.

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 ...

Low-intensity Pulsed Ultrasound Enhances NK Cell Adoptive Therapy by Modulating the Wnt/β-catenin Signaling Pathway

open access: yesBIO Integration
Natural killer cell adoptive therapy is a novel immunotherapy strategy for the treatment of multiple refractory tumors, including ovarian cancer. However, natural killer cells’ anti-tumor effectiveness is limited by their viability and cytotoxicity.

Invariant Natural Killer T Cells

open access: yesAntibodies, 2013
Invariant Natural killer T cell (iNKT cells) are a subset of T cells, which are narrowly defined as a T cell lineage expressing a semi-invariant CD1d-restricted T cell Receptors (TCRs) composed by Vα24-Jα18/Vβ11 in human, and Vα14-Jα18/Vβ8,Vβ7, and Vβ2 ...

Natural killer cells in herpesvirus infections [PDF]

open access: yes, 2017
Natural killer (NK) cells are potent innate cytotoxic lymphocytes for the destruction of infected and transformed cells. Although they were originally considered to be ready-made assassins after their hematopoietic development, it has recently become ...

Natural killer-cell counts are associated with molecular relapse-free survival after imatinib discontinuation in chronic myeloid leukemia: the IMMUNOSTIM study

open access: yesHaematologica, 2017
Despite persistence of leukemic stem cells, patients with chronic myeloid leukemia who achieve and maintain deep molecular responses may successfully stop the tyrosine kinase inhibitor imatinib.

Crystallization and preliminary crystallographic data for the augmenter of liver regeneration [PDF]

open access: yes, 1997
A new cellular growth factor termed augmenter of liver regeneration (ALR) has been crystallized. ALR has been shown to have a proliferative effect on liver cells while at the same time producing an immunosuppressive effect on liver-resident natural ...
