In recent years, it has been emphasized the role of the crosstalk between natural killer (NK) cells and monocyte-derived dendritic cells dendritic cells (moDCs) in the regulation of the early phases of innate immunity innate immunity and of the subsequent adaptive immune responses. NK cells and DCs coordinate their response communicating...

Natural killer cells are an essential component of the innate immune system and play a crucial role in immunity against malignancies, without, at difference with T cells, requiring antigen priming or inducing graft-versus-host-disease. Hence, Natural Killer cells can provide a valuable source of allogeneic "off-the-shelf" adoptive therapy and...

In the present study, we report the analysis of NK cells derived from patients suffering from a rare ovarian cancer histotype of clear cell carcinoma (OCCC) resistant to conventional chemotherapies. We analyzed the phenotype of NK cells derived from peripheral blood (PB) and peritoneal fluid (PF) and evaluated cytotoxic interactions between NK...

Human Natural Killer (NK) cells are innate lymphocytes, short-living and providing rapid responses against viral infections and tumors. Adaptive NK cells are an NK cell subpopulation arising upon cytomegalovirus (CMV) infection, characterized by the expression of the CD94/NKG2C heterodimer (a HLA-E-specific activating receptor), by a highly...

Human NK cells can control tumor growth and metastatic spread thanks to their powerful cytolytic activity which relies on the expression of an array of activating receptors. Natural cytotoxicity receptors (NCRs) NKG2D and DNAM-1 are those non-HLA-specific activating NK receptors that are mainly involved in sensing tumor transformation by the...

BackgroundNatural Killer cells (NKs) represent the innate counterpart of TCR & alpha;& beta; lymphocytes and are characterized by a high anti-tumor and an anti-viral cytotoxic activity. Recently, it has been demonstrated that NKs can express PD-1 as an additional inhibitory receptor. Specifically, PD-1 was identified on a subpopulation of...

Peritoneal carcinomatosis (PC) is a rare disease defined as diffused implantation of neoplastic cells in the peritoneal cavity. This clinical picture occurs during the evolution of peritoneal tumors, and it is the main cause of morbidity and mortality of patients affected by these pathologies, though cytoreductive surgery with heated...

The highly destructive mechanisms by which the immune system faces microbial infections is under the control of a series of inhibitory receptors. While most of these receptors prevent unwanted/excessive responses of individual effector cells, others play a more general role in immunity, acting as true inhibitory checkpoints controlling both...

Surgical resection, chemotherapy and radiotherapy were, for many years, the only available cancer treatments. Recently, the use of immune checkpoint inhibitors and adoptive cell therapies has emerged as promising alternative. These cancer immunotherapies are aimed to support or harness the patient's immune system to recognize and destroy cancer...

Natural killer (NK) cells were originally defined as effector lymphocytes of innate immunity characterized by the unique ability of killing tumor and virally infected cells without any prior priming and expansion of specific clones. The "missing-self" theory, proposed by Klas Karre, the seminal discovery of the first prototypic HLA class...
