Due to a technical problem, the journal volumes in many of the references to the manuscript Bennett et al. (November 1996, 184:1845–1856) were incorrect. A complete and correct reference list follows. Trinchieri. 1983. Human natural killer cells analyzed by B73.1, a monoclonal antibody blocking Fc receptor functions. I. Characterization of the lymphocyte subset reactive with B73.1. Natural kill...
Background: Natural Killer (NK) cells, through mechanisms such as cytotoxicity and cytokine production, are among the first line of defence against infections. The ability of NK cytotoxicity is related to Killer cell immunoglobulin-like receptors (KIR) found on the cell surface. Interaction between KIRs and human leukocyte antigen (HLA) class I molecules regulate NK cells responses to eliminate...
Introduction: Immunological processes are most important in recurrent spontaneous abortion(RSA). According to studies T lymphocytes and natural killer cells(NK cells) are two effective cell groups in RSA. The aim of this study was to investigate the percentage and absolute number of natural killer(NK) cells in women with RSA with unknown etiology. Methods: 24 Women with a history of recurrent ...
The base of this study has been demonstrated the use of different drugs and dosages on different tumour cell lines and finally the effect of these drugs on natural killerllimphokine activated killer (NK/LAK) Killing. Tumour cells as target , mononeuclear cell activated with inter leukin-2(LAK) as effector, anti cancer drugs like tamoxifen , pentoxifylline , cycloheximide and cisplatin as stimul...
background: mature t/ nk-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. most of the previous studies have focused on mature b-cell lineage leukemias and there is a paucity of data on mature t/nk-cell lineage leukemias. we, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features. methods: all cas...
During the natural killer (NK) cell immune response, cytoskeletal components, adhesion and signaling molecules and ligand-specific receptors are involved in the formation of the natural killer cell immune synapse (NK-IS), a highly organized supramolecular structure assembled at the interface of the interacting cells that regulates the NK cell activation and decides the target cell fate. In this...
Background: Natural killer (NK) cells originate from the differentiation of hematopoietic stem (HSCs) in common lymphoid progenitor pathway, and HSCs can be obtained umbilical cord blood (UCB). Comparative studies NK cell between cultured freshly isolated are important development therapy for cancer. This study aimed to compare maturation stages newly HSC samples using interleukin-2 absence fee...

background: schizophrenia has been associated with altered immunity. different studies regarding natural killer cell activity (nka) in schizophrenic patients have shown inconsistent results. objectives: to evaluate nk cell activity in schizophrenic patients in comparison with healthy control individuals. methods: 30 medication-free schizophrenic patients and 41 healthy sex, age and smoking st...
