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 ...

Cord blood Vα24-Vβ11 natural killer T cells display a Th2-chemokine receptor profile and cytokine responses [PDF]

open access: yes, 2011
Background: The fetal immune system is characterized by a Th2 bias but it is unclear how the Th2 predominance is established. Natural killer T (NKT) cells are a rare subset of T cells with immune regulatory functions and are already activated in utero ...

Dynamic Natural Killer Cell and T Cell Responses to Influenza Infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Influenza viruses have perplexed scientists for over a hundred years. Yearly vaccines limit their spread, but they do not prevent all infections. Therapeutic treatments for those experiencing severe infection are limited; further advances are held back ...

Natural killer T cells and the regulation of asthma [PDF]

open access: yesMucosal Immunology, 2009
A crucial role has been suggested for invariant natural killer T cells (iNKT) in regulating the development of asthma, a complex and heterogeneous disease characterized by airway inflammation and airway hyperreactivity (AHR). iNKT cells constitute a unique subset of T cells responding to endogenous and exogenous lipid antigens, rapidly secreting a ...

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 ...

Frequent Mutations in Natural Killer/T Cell Lymphoma

open access: yesCellular Physiology and Biochemistry, 2018
Extranodal natural killer (NK)/T cell lymphoma (ENKTL-NT or NKTCL), with its aggressive nature and poor prognosis, has been widely studied to discover more effective treatment options.

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.

Natural killer T cells: Know thyself [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
There are two main reasons why natural killer T (NKT) cells fascinate immunologists. First, they exhibit a unique melange of properties found in innate immune cells as well as the properties of conventional T cells, part of adaptive immunity (1–4). Second, NKT cells exercise a determining influence on a variety of immune responses in mice, ranging from

Extranodal Natural-Killer/T-Cell Lymphoma, Nasal Type

open access: yesAdvances in Hematology, 2010
The World Health Organization (WHO) classification recognizes 2 main categories of natural killer (NK) cell-derived neoplasms, namely, extranodal NK/T-cell lymphoma, nasal type, and aggressive NK-cell leukaemia.

Updating targets for natural killer/T-cell lymphoma immunotherapy

open access: yesCancer Biology & Medicine, 2021
Natural killer/T-cell lymphoma (NKTCL) is a highly invasive subtype of non-Hodgkin lymphoma, typically positive for cytoplasmic CD3, CD56, cytotoxic markers, including granzyme B and TIA1, and Epstein-Barr virus (EBV).
