Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...
Among immune system components natural killer (NK) cells are the first line of defence against tumor cells. The decreasing activity of these cells can be associated with carcinogenesis, in situ tumor growth and metastasis of different cancers, viral infections, immunodeficiency syndroms and autoimmune diseases. In this study natural killer activity of peripheral blood mononuclear cells (Effecto...
to clarify the effect of γδ t cells and invariant natural killer t (inkt) cells in pathophysiology of dyspeptic disorders, number of these two cells in patients with non-ulcer dyspepsia (nud), peptic ulcer disease (pud), and gastric cancer (gc) were compared.patients with dyspepsia were divided into three groups of nud, pud, and gc according to their endoscopic and histopathological examination...
background: major depressive disorder is a mental disorder characterized by a pervasive and persistent low mood that is accompanied by low self-esteem and loss of interest or pleasure in normally enjoyable activities. depression is associated with multiple immunological disorders. aim of the present study was to determine correlation between percentage of circulating nk cells and major depressi...
Objectives: the purpose of the present study was to examine the relationship between natural killer cells and the clinical trend of depression before and after treatment. Methods: the subjects were 15 patients diagnosed with primary major depression, and 15 non-patients selected from among medical students and laboratory staff, matched in terms of age and sex. In the patient group, 6 out of 15 ...
Objective Inflammation plays an important role in endometriosis and adenomyosis. Progestin has been used for symptomatic treatment of adenomyosis, although its effect on inflammation has not been studied. We conducted a randomized controlled study to investigate the changes of immune cell expression, i.e. macrophages and natural killer cells, in the tissue obtained from women with adenomyosis w...
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...
