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

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
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 ...

Efficient lysis of rhabdomyosarcoma cells by cytokine-induced killer cells : implications for adoptive immunotherapy after allogeneic stem cell transplantation [PDF]
Background: Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and has a poor prognosis. Here we assessed the capability of ex vivo expanded cytokine-induced killer cells to lyse both alveolar and embryonic rhabdomyosarcoma cell lines ...

Natural Killer Cells in Psoriasis [PDF]
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,

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

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

Natural killer cell deficiency [PDF]
Natural killer (NK) cells are part of the innate immune defense against infection and cancer and are especially useful in combating certain viral pathogens. The utility of NK cells in human health has been underscored by a growing number of persons who are deficient in NK cells and/or their functions. This can be in the context of a broader genetically
