Reciprocal Activating Interaction between Natural Killer Cells and Dendritic Cells
We analyzed the interaction between human peripheral blood natural killer (NK) cells and monocyte-derived immature dendritic cells (DC). Fresh NK cells were activated, as indicated by the induced expression of the CD69 antigen, and their cytolytic activity was strongly augmented by contact with lipopolysaccharide (LPS)-treated mature DC, or with immature DC in the presence of the maturation sti...
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 کاملActivating natural killer (NK) cytotoxicity of canine CD5−CD21− cells requires low surface CD5 density NK cells
Natural killer (NK) cells play a crucial role in regulating immune functions. Few studies have characterized canine NK cells. We previously demonstrated that canine peripheral blood lymphocytes (PBLs) with a low surface CD5 density (CD5lo) are considered a critical NK population. Natural killer cells in most mammals do not express T-cell markers, but canine CD5lo cells express surface molecules...
متن کاملNatural Killer Dendritic Cells Enhance Immune Responses Elicited by α-Galactosylceramide-Stimulated Natural Killer T Cells
Natural killer dendritic cells (NKDCs) possess potent anti-tumor activity, but the cellular effect of NKDC interactions with other innate immune cells is unclear. In this study, we demonstrate that the interaction of NKDCs and natural killer T (NKT) cells is required for the anti-tumor immune responses that are elicited by α -galactosylceramide ( α -GC) in mice. The rapid and strong expression ...
متن کاملAnti-EGFR antibody cetuximab enhances the cytolytic activity of natural killer cells toward osteosarcoma.
PURPOSE Osteosarcoma and Ewing's sarcoma are the most common bone tumors in children and adolescents. Despite intensive chemotherapy, patients with advanced disease have a poor prognosis, illustrating the need for alternative therapies. Sarcoma cells are susceptible to the cytolytic activity of resting natural killer (NK) cells which can be improved by interleukin (IL)-15 stimulation. In this s...
