Natural killer cell-mediated immunopathology in recurrent pregnancy losses

Exploration 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 ...

Atividade lítica de células natural "killer" durante a infecção pelo HIV-1 em indivíduos brasileiros [PDF]

, 2001
Natural killer cells are increasingly being considered an important component of innate resistance to viruses, but their role in HIV infection is controversial.

Unraveling Natural Killer T-Cells Development

Frontiers in Immunology, 2018
Natural killer T-cells are a subset of innate-like T-cells with the ability to bridge innate and adaptive immunity. There is great interest in harnessing these cells to improve tumor therapy; however, greater understanding of invariant NKT (iNKT) cell ...

Candida albicans evades NK cell elimination via binding of Agglutinin-Like Sequence proteins to the checkpoint receptor TIGIT

Nature Communications, 2022
Natural killer cells have emerged as critical immune cells in the response to fungal infection. Here the authors identify how Candida albicans evades the natural killer cell response via expression of ligands that directly modify the natural killer cell ...

Unbinding and unfolding of adhesion protein complexes through stretching: Interplay between shear and tensile mechanical clamps [PDF]

Proteins: Structure, Function, and Bioinformatics 82 (2014) 3144-3153, 2015
Using coarse-grained molecular dynamics simulations, we analyze mechanically induced dissociation and unfolding of the protein complex CD48-2B4. This heterodimer is an indispensable component of the immunological system: 2B4 is a receptor on natural killer cells whereas CD48 is expressed on surfaces of various immune cells. So far, its mechanostability

Impaired natural killer cell phenotype and function in idiopathic and heritable pulmonary arterial hypertension [PDF]

, 2012
BACKGROUND: Beyond their role as innate immune effectors, natural killer (NK) cells are emerging as important regulators of angiogenesis and vascular remodeling.

Highly activated and expanded natural killer cells for multiple myeloma immunotherapy

Haematologica, 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 ...

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

Haematologica, 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 ...

A biophysical model of cell adhesion mediated by immunoadhesin drugs and antibodies [PDF]

, 2010
A promising direction in drug development is to exploit the ability of natural killer cells to kill antibody-labeled target cells. Monoclonal antibodies and drugs designed to elicit this effect typically bind cell-surface epitopes that are overexpressed on target cells but also present on other cells.

Deprenyl, an old drug with new anticancer potential: Mini review [PDF]

arXiv, 2021
The anticancer potential of monoamine oxidase (MAO) was observed in pre-clinical assays conducted with cell cultures and animals. L-Deprenyl (DEP) causes apoptosis in melanoma, leukemia and mammary cells. High-dose DEP has shown toxicity in mammary and pituitary cancers, as well as in monoblastic leukemia, in rats.
