THE CYTOTOXICITY PATHWAY OF NATURAL KILLER CELLS IN CORD BLOOD COMPARED TO P ERIPHERAL BLOOD
The cytotoxic activity of natural killer cells is usually tested by radioactive assay CSI Cr release assay), which detects the release of cytoplasmic contents after plasma membrane disintegration of dying cells. In contrast to this indirect evaluation of cytotoxicity, the assessment of cell damage by flow cytometry aims to provide a more exact characterization of the death pathway via detec...
متن کاملThe State of Peripheral Blood Natural Killer Cells and Cytotoxicity in Women with Recurrent Pregnancy Loss and Unexplained Infertility
Objective : The prognostic value of peripheral natural killer (pNK) cells, as a screening test in women with recurrent pregnancy loss (RPL) and unexplained infertility is still a matter for discussion. The aim of this study was to compare the percentage of circulating CD56+NK cells, CD69 and perforin markers between women with unexplained infertility and RPL with healthy control group. Material...
متن کاملLysis of tumor cells by natural killer cells in mice is impeded by platelets.
Natural killer (NK) cells provide effective antitumoral activity in the blood stream of mice, leading to reduced metastasis. There are, however, tumor cells that metastasize despite the presence of an intact NK system. The capability of tumor cells to induce platelet aggregation, on the other hand, correlates with their enhanced metastatic potential. A counteractive role of platelets for the NK...
متن کاملModulation of natural killer cell anti-tumor reactivity by platelets.
Natural killer (NK) cells may prevent tumor progression and metastasis. Apart from the direct interaction with their targets, NK cell activity is influenced by the reciprocal interplay with other hematopoietic cells. While the interaction of NK cells e.g. with dendritic cells or monocytes/macrophages is well characterized, knowledge regarding their crosstalk with platelets, another central comp...
متن کاملIncreased Natural Killer Cells Activity in Schizophrenic Patients
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...
