The Critical Role of the Tumor Microenvironment in Shaping Natural Killer Cell-Mediated Anti-Tumor Immunity
Considerable evidence has been gathered over the last 10 years showing that the tumor microenvironment (TME) is not simply a passive recipient of immune cells, but an active participant in the establishment of immunosuppressive conditions. It is now well documented that hypoxia, within the TME, affects the functions of immune effectors including natural killer (NK) cells by multiple overlapping...
متن کاملNatural killer cells: role in local tumor growth and metastasis
Historically, the name of natural killer (NK) cells came from their natural ability to kill tumor cells in vitro. From the 1970s to date, accumulating data highlighted the importance of NK cells in host immune response against cancer and in therapy-induced antitumor response. The recognition and the lysis of tumor cells by NK cells are regulated by a complex balance of inhibitory and activating...
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...
متن کاملNatural killer cells and solid tumors.
Natural killer (NK) cells play an important role in the innate immune response against cancer, in particular in the elimination of tumor metastases and small tumors. NK cell-mediated control of large solid tumors is usually not efficient, although tumors often express high amounts of activating ligands and low levels of inhibitory ligands, such as MHC class I. Thus, we assume that these tumors ...
متن کاملThe Effects of Dienogest on Macrophage and Natural Killer Cells in Adenomyosis: A Randomized Controlled Study
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...
