Natural Killer Cells in Asthma [PDF]

Frontiers in Immunology, 2013
The worldwide prevalence, morbidity, and mortality of asthma have dramatically increased over the last few decades and there is a clear need to identify new, effective, therapeutic and prophylactic strategies. Despite high numbers of NK cells in the lung

Natural killer cells and natural killer T cells in Lyme arthritis [PDF]

Arthritis Research & Therapy, 2013
Abstract Introduction Natural killer (NK) and natural killer T (NKT) cells provide a first line of defense against infection. However, these cells have not yet been examined in patients with Lyme arthritis, a late disease manifestation. Lyme arthritis usually resolves with antibiotic treatment.

Activation of natural killer cells during microbial infections. [PDF]

, 2011
Natural killer (NK) cells are large granular lymphocytes that express a diverse array of germline encoded inhibitory and activating receptors for MHC Class I and Class I-like molecules, classical co-stimulatory ligands, and cytokines.

The activating receptors 2B4 and NTB-A, but not CRACC are subject to ligand-induced down-regulation on human natural killer cells [PDF]

, 2010
Activation of natural killer cells can be mediated by different receptors. Stimulation of the receptors 2B4, NTB-A and CRACC, members of the SLAM-related receptor family, induces cytotoxicity and cytokine production.

Activation of human natural killer cells by Plasmodium falciparum [PDF]

, 2003
The purpose of work described in this thesis was to (i) determine the contribution of innate immune responses to the early pro-inflammatory cytokine response to Plasmodium falciparum, (ii) describe the kinetics and ...

Short communication: NKG2C+ NK cells contribute to increases in CD16+CD56- cells in HIV type 1+ individuals with high plasma viral load. [PDF]

, 2013
Chronic HIV-1 infection results in the expansion of both NKG2C+ and CD16+CD56- human natural killer cells. NKG2C+ cells proliferate in response to human cytomegalovirus (HCMV) and expansion of the dysfunctional CD56-CD16+ natural killer (NK) cells is ...

Natural killer cells [PDF]

Current Biology, 1999
Perhaps, but probably not a long or healthy life. There is only one documented human case of an absolute NK cell deficiency, which was associated with recurrent life-threatening bacterial and viral infections.

SnapShot: Natural Killer Cells

Cell, 2020
NK cells are broadly distributed innate lymphoid cells (ILCs) encompassing distinct populations based on CD11b and CD27 expression in mice or CD56 intensity in humans. Involved in anti-viral and anti-tumor immunity thanks to their cytokines and chemokines secretion as well as their cytotoxic capabilities, NK cells have emerged as a promising ...

Matched sizes of activating and inhibitory receptor/ligand pairs are required for optimal signal integration by human Natural Killer cells [PDF]

, 2010
It has been suggested that receptor-ligand complexes segregate or co-localise within immune synapses according to their size, and this is important for receptor signaling.

Natural Killer Cells in Psoriasis [PDF]

Journal of Innate Immunity, 2011
Psoriasis is one of the most common immune-mediated disorders. There is evidence that it is mediated by Th1 and, more recently, Th17 cells. The cytokine pattern, particularly the dominance of TNF-α, implicates the innate immune system in psoriasis pathogenesis. Of the many components of the innate immune system known to be involved in psoriatic lesions,
