Natural killer cells

open access: yesHematology/Oncology and Stem Cell Therapy, 2015
Natural killer (NK) cells constitute our bodies' frontline defense system, guarding against tumors and launching attacks against infections. The activities of NK cells are regulated by the interaction of various receptors expressed on their surfaces with cell surface ligands.

Interferon therapy shifts natural killer subsets among Egyptian patients with chronic hepatitis C

open access: yesBrazilian Journal of Infectious Diseases, 2010
Natural killer cells can be divided into five subpopulations based on the relative expression of CD16 and CD56 markers. The majority of natural killer cells are CD56dim, which are considered to be the main cytotoxic effectors.

Recognition of Human Histocompatibility Leukocyte Antigen (HLA)-E Complexed with HLA Class I Signal Sequence–derived Peptides by D94/NKG2 Confers Protection from Natural Killer Cell–mediated Lysis [PDF]

open access: yes, 1998
Human histocompatibility leukocyte antigen (HLA)-E is a nonclassical HLA class I molecule, the gene for which is transcribed in most tissues. It has recently been reported that this molecule binds peptides derived from the signal sequence of HLA class I ...

Natural killer cells in hepatitis B virus infection

open access: yesBrazilian Journal of Infectious Diseases, 2015
Natural killer cells are a unique type of lymphocytes with cytotoxic capacity, and play important roles against tumors and infections. Recently, natural killer cells have been increasingly valued in their effects in hepatitis B virus infection.

Killer instincts: natural killer cells as multifactorial cancer immunotherapy

open access: yesFrontiers in Immunology, 2023
Natural killer (NK) cells integrate heterogeneous signals for activation and inhibition using germline-encoded receptors. These receptors are stochastically co-expressed, and their concurrent engagement and signaling can adjust the sensitivity of ...

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.

Advances in augmenting infiltration of active natural killer cells into pediatric and adult solid tumors

open access: yesMolecular Therapy: Oncology
Although adoptive natural killer cell therapies have been safe and somewhat effective in hematological malignancies, their performance in solid tumors is hindered by the solid tumor microenvironment, which impairs natural killer cell trafficking and ...

Unraveling Natural Killer T-Cells Development

open access: yesFrontiers 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 ...

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 ...
