Innate lymphoid cells (ILCs), including NK cells, contribute to barrier immunity and tissue homeostasis. In addition to the role of uterine NK cells in placentation and fetal growth, other uterine ILCs (uILCs) are likely to play roles in uterine physiology and pathology. In this article, we report on the composition of uILCs in the endometrium during the luteal phase and in the decidua during e...
background: hla-g is a nonclassical hla class i molecule which, when elevated in tumor cells, is one of the main factors involved in tumor evasion of immune responses including nk and t cells. objective: to evaluate the effect of hla-g downregulation on nk cell cytotoxicity in tumor cell lines. methods: the expression level of hla-g was measured by real-time pcr and flowcytometry after transfec...
Introduction: Functional defect in immune cells is the prominent feature in hematological malignancies that lead to the expansion of tumor cells. Using immunostimulatory cytokines is one of the new therapeutic approaches. This study aimed to investigate the effect of IL-27 on the activity of bone marrow-NK cells of chronic lymphocytic leukemia (CLL) patients in vitro. Materials and Methods: 10 ...
ABSTRACT Natural Killer cells (NKs), are considered an important first line of defence and were originally defined by their ability to kill certain tumor cells and virally infected cells. Our aim is to study expression of HLA class-Ia on tumor cell lines and their susceptibility of NK cells. In this study MDA-MB-468 tumor cell line (NCB1, C208) That derived from human breast adenocarcino...
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...
Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...
peripheral t-cell lymphomas are a group of heterogeneous disorders and according to who classification, are categorized into nodal and extranodal forms. nk/t-cell lymphoma, nasal type, is a subtype of extranodal peripheral t-cell lymphoma and commonly presents as a midfacial destructive lesion. this disorder is more prevalent in asia and south america and has a strong association with epstein b...
results the ovarian hormones level showed a significant difference between the experimental and control groups (p < 0.05). furthermore, the unk cell population showed a significant difference between the two groups (p < 0.05). conclusions increased ovarian hormones due to low-dose aspirin administration resulted in decline in the unk cells number, which may be effective in successful pregnancy....
